Hybrid is as Hybrid does
 

[FONT=Calibri][SIZE=3]I grow several hybrids. Hybrids like Sungold, Better Boy, Big Beef, Mountain Magic and Jetstar and others all have things worth paying for. That is what keeps me coming back year after year to buy the seeds. A lot of thought and work goes into creating a hybrid worthy for the tomato market. The parents in a commercial hybrid cross will consistently produce the desired results. The seed is predictable and always what the customer expects to get. However, I would not give you a nickel for a bucketful of the saved seed from any of them.[/SIZE][/FONT]

[FONT=Calibri][SIZE=3]As many of you know, when you try to re-grow hybrid seeds you mostly end up with something that is nothing like the parent and quite often is unfit for human consumption. I cannot imagine wanting to buy second or third generation seeds from one of these well-known hybrids. [/SIZE][/FONT]

[SIZE=3][FONT=Calibri]So, why would anyone pay for someone’s second or third generation of seeds from a hybrid that was unproven? If leftover seeds from Sungold are junk, isn’t it likely that seed from some amateurs crossing project is going to be a wasted spot in your garden? [/FONT][/SIZE]

[SIZE=3][FONT=Calibri]If you let a hybrid tomato self-pollinate, then every generation the number of mixed or non-pure (you could still call them hybrid) tomatoes will diminish by 50%. So if the first generation is 100% hybrid, the next generation, or F2 has 50% hybrids mixed in, the next generation will have 25% and the next 12.5% etc. These are not hybrids that are consistent and predictable. These are just random plants that will most likely be undesirable. F2 or even F5 seeds are still hybrid seeds. I am in a state of disbelief at the number of companies jumping into this game. There is even one company calling a tomato a “Blend”. That is how someone who has made a career bad mouthing hybrid seeds, sells hybrid seeds. [/FONT][/SIZE]

[SIZE=3][FONT=Calibri]Even seeds that are six generations away from the initial cross will have about 30 seeds out of every 1000 that are still hybrid. So if they are selling 30 seeds in a pack and 250 people purchase a pack of seeds what we are going to see is about 230 tomatoes that do not match the description. These 230 tomato plants are more than likely just junk. What will happen to these 230 tomatoes? They will be declared “new” or “mutations”. They will be named, passed around, and they too will be unstable and produce even more false assumptions and renaming. [/FONT][/SIZE]

[FONT=Calibri][SIZE=3]There is going to be a glut of crappy named varieties hit this hobby in the next five years like the world has never seen. Not only that, but there will be hundreds of growth habits, shapes, sizes, and colors of tomatoes all with the SAME name. Also, there will be hundreds of tomatoes that are nearly IDENTICAL that will have DIFFERENT names too. This can’t be good for this hobby. The world does not need 10,000 new mediocre tomatoes.[/SIZE][/FONT]

[SIZE=3][FONT=Calibri]What is the motivation for doing this? [/FONT][/SIZE]

[SIZE=3][FONT=Calibri]I find it hard to believe seed vendors are selling unstable hybrids, and billing them as open pollinated. [/FONT][/SIZE]

Well done Steve.

What also bothers me is that the most of the persons buying these unstable hybrids don't really know what you posted above, may just put out one plant and think they have what they should have, which in reality is wrong b'c a responsible hybridizer will put out maybe 20 or so plants in just one season for a particular cross, making selections, sometimes many selections, and treating each of those lines separately. And doing it all over again for each of those selections.

When he or she makes some final decisions as to which selections are close to what the hybridizer is looking for that looks good, or even what's not being looked for that looks good and tastes good, then they have to be grown out for the generations you noted above until stable.

Which is why in my list of experiemental ones in my current seed offer, now closed, I spoke to that issue directly, for the three that I listed.All are works in progress as I see it.

Carolyn

Well said. If they're going to sell unstable lines they should at least let people know what they are. I personally like the opportunity to get early access to some interesting lines, but I know what I am getting into with them.

Unfortunately without full disclosure, as you said a large number of gardeners may plant out one plant of a F3 or F4 line and all carry a different version forward if they are seed savers, resulting in mass confusion a few years from now.

I'm afraid this trend of marketing unfinished lines will undermine credibility of what I believe may become a robust and interesting collection of small seed companies focusing on the tomato home gardner niche. We can/should do as good a job on product/seed quality as the big boys.

Here's a perfect example where a recent cross is being sold as a stable OP variety - and to make matters worse,[B] one of the parents has mysteriously changed from Anna Russian to Prue. (!)[/B]
[I]
"throws hearts and pastes"[/I] Does this statement absolve the seller of selling something unstable to unsuspecting customers?

No. Absolutely not.

I know that I would not want to waste an entire tomato growing season, just to find out the hard way that I'm growing a bunch of genetically unstable garbage.

I know my antenna went up when I saw threads being hijacked by new, super duper tomatoes I had never heard of. Most seem to have a common source of purchase. I have seen postings on other sites that are incredibly blatant commercials for these "unique" creations.

I don't actually grow a lot of hybrids, but like the OP, I appreciate knowing exactly what I will be getting.

I think there are a couple of different mentalities at work.

Some people just don't understand that for the average gardener who might put out 6 tomato plants an off type is going to be upsetting.

That's a risk we all take though as there is always a chance of a crossed seed, I know I have gotten them from large vendors as well as small. But it's different if someone is selling something they know is going to segregate into X different phenotypes.

Others are rushing things to market to be first or exclusive. The same mentality that causes some to rename varieties so they can be the only ones with the uber rare version. It takes years to stabilize a cross and if money is your end goal in breeding then those last 3-4 years to fine tune things appear to be tempting to skip.

It's unfortunate but I think it's going to get a bit worse before it gets any better.

It makes me angry because some few are merchandising others. I guess if you have your own seed selling site and you want to make hype there, it is your business." Let the buyer beware" will eventually define your business. But to come on community forums and direct others to your site because you have some fake "exclusive" is taking advantage of the gardening community and seems in especially poor taste.

Are they married?

doublehelix, I have grown out a few hybrid seed form tomatoes and find the results a mess; but with some hybrid bell pepper seed I have seen very little difference between the hybrid and the grow outs from the seed. When I first grew out a few hybrid pepper seed about 10 years ago I was expecting the kind of crazy variety that I got from tomatoes. What I got were similar plants with similar fruit and characteristics so I kept growing a few every year and still am getting the same kind of results. Every once in a while one will turn out to be a plant that produces markedly smaller fruit but that has been the rare exception. I have been quite surprised by these results. I am no scientist and don't understand the genetics behind hybridization but it would seem to me that the parents must be very similar to the resulting hybrid for this to be the case.

Well, I can't pretend to have seen all the promotional material being discussed here, but I don't think there is really any risk of undermining the extraordinary products which are coming from serious breeders like yourself.

I had a look at [URL="https://www.mariannasheads.com/create-heirlooms.html"]this page[/URL], and it seems to me that the 'unfinished lines' are being marketed to a different market segment, not the gourmet market which you serious breeders are catering to. This seed seller is clearly targeting a 'sentimentality' niche market ("my own tomato"), as well as selling the experience of selection in a very scaled down way, to home gardeners who are not breeders but want a small taste of that experience. If the results are 'genetically unstable crap' as is anticipated, well that is the kind of taste of the experience that they'll get. 8-) I would expect that experience to foster a deeper awareness and appreciation for the work that goes into the awesome, stable lines that are being produced by professionals like yourselves, and ultimately benefit your business. :wait:

For the smaller percentage of customers that actually continue the growout to stabilize and name their own variety, yes, it may result in circulation of some mediocre named varieties that only a mother could love:shock:, but I doubt that many will end up on the market. If so, I wouldn't expect them to last long in the face of competition with really excellent varieties that have been produced and stabilized with due care.

Yes, we could end up with some very similar (or the same) varieties which have unique names. As long as the parentage is acknowledged, their sibling status will be obvious enough. From a genetic diversity perspective, that is really not a bad thing for the ol tomato genome. Subtle traits, such as tolerance of the different pest/disease profile or climate/soil conditions in specific locations, may end up represented in the 'sibling seed' bank as a result, which would be excluded when the same cross is fully stabilized for optimal performance in one breeder's location. So there is a possible up side to the development of this 'amateur breeder' market.

Sorry to play devil's advocate, but I'm not convinced that this is a bad thing (in itself) but, like most things, it can certainly be negative if there is misrepresentation involved.:?!?:

I have two thoughts:

1. The cream rises to the top.

2. Different strokes for different folks.

I do also agree that the page linked by bower, and Tom Wagner's "unfinished" lines do have an appreciative audience, and when clearly labeled as segregating lines they may be useful for breeders and some passionate growers.

Points well taken. Market niches are a good thing, and to the extent the lines are adequately described - no harm done to the seed customer. I hope the naming confusion passes quickly - but I am less confident of that.

The ones in the link bower posted are clearly marked, and I don't think those are an issue.

I like a lot of Tom's varieties, they've certainly perked my interest in breeding tomatoes, I figure I've gotten a little practice making selections and I've gotten some interesting genetics that would likely have taken me several years to develop on my own. But if you don't know how he works it's not evident from the variety descriptions; we had a few members here get surprised with their results last year.

I worry that as some of the work on 'boutique' breeding programs becomes more widely known it may get a black eye when unknowing gardeners buy unstable lines. When they get unexpected results those potential customers for this market may be lost forever.

Bower, you linked to Bill Jeffers crosses and I've know Bill for many many years. He's a talented not so amateur breeder and does it as a sideline and has an excellent full time job elsewhere.

Bill explains what do with his offerings, as in making selections, etc., as I recall, I didn't read the whole page b'c I've got to pack more tomato seeds and ge tthem out for my seed offer, and Bill also gives the full parentage so that if folks want to look those up and see what they are they can do so. Agreed that most probably won't have enough grasp of tomato genetics to predict what might ensue, but for those interested and have enough room to do the growouts, I think it's great.

I have three crosses in the Experimental Section of my seed offer and warn about having enough room to do growouts,etc. , but I know from past experiences that many do and some only put out one plant.

Bill was the one who did the NAR X Brandywine which ultimately becameDixiewine which I haven't grown yet but have the seeds and may do so this summer. Since I introduced NAR and at one time liked Brandywine I asked Bill for some F2 seeds and he sent them ASAP but I only did one growout and didn't pursue it since I was at my new place and didn't have the acreage that I used to have.

I admire what Bill has done, and what varieties he's working on now, and feel that he's being honest and straightout, no misrepresentation, with his offerings, as some aren't, as to parentage and unstable lines being offered.

Just my opinion having known Bill, for what, maybe 15 years at least.

Carolyn, who never has made a deliberate cross, but has dehybridized a few varieties to stability, and has had some amusing results appear, viz., three plants of Cherokee Green put out for seed stock and two had pure white lousy tasting fruits, and then the two somatic mutations that appeared,now those were fun.:)

Mark, I was typing my response while you were posting yours and I see we agree on who is "serious" and gives all the info for a cross as opposed to those who may not.

I can't really spaek to Tom's potato ones except I can note that for the new tomato ones when he first put up his tomato ones there was outrage on the part of many since he never said those tomato named ones were not stable. and the prices being asked were high as several noted.

But he then went back and did note that the new tomato ones were not stable, and he did answer questions here about what to expect and select for and what to discard.

Yes, I had a look at the offerings on that page, and they look like good parentage to work with in a cross. I haven't had my experience of growout yet, the pleasure awaits me. :D:twisted:

Many years ago Bill sent me F1 seed of his cross Indian Stripe x Sungold. It got me started on making my own crosses, and tomato breeding in general. I have no doubts his (and Tom's) current offerings will get others similarly excited and engaged.

Slight correction: I have not given out full pedigrees in each and every case, but I am willing to do that in every case where I know both parents for sure. In other words, a couple of the crosses were done by bees; but in cases where I personally made the cross by hand, I will either give out the pedigree with the public description, or privately to a recipient of the seeds.

Yes, I have made mistakes in my tomato life, just like in the other aspects of my 65 years of life. Water under the bridge, and no use looking back. Yes, I have named lines stuff like Brannar Line, Cherokee Tiger Line, etc. But I will not make the same mistake of prematurely assigning a name to an unstable tomato line ever again from this day forward. Apparently, some folks just don't get it. So, from now on the all my unstable lines will all carry letters and numbers instead. And I will strongly encourage others to do the same whether to good avail or not. Time will tell.

I could say a whole lot more about the issues discussed in this thread, in other related threads, and at other Web sites, but I think I'll bite my tongue and bind my fingers at this time and in this place.

May each and every tomato gardener have a most excellent 2013 season, and may the forces of Nature be kind to our gardens.

I too am not convinced this is entirely bad. There are lots of folks who love to tinker with genetics. With that said, what I foresee is a huge number of mediocre "varieties" being dumped onto the market over the next 5 years. The result will be cream rising to the top but this will take a number of years to sort out.

On a different note, using dna testing to stabilize desirable traits is close to being available to the average grower. This would enable anyone to stabilize a variety in short order while retaining desirable traits. In other words, super tomatoes are more and more feasible.

DarJones

I don't think this is any different than any other industry when it comes to the mix of the "type" of companies that are in it. There are a number that try to do they very best they can. There are others that do a much poorer job because they just down know any better or their standards are pretty low. Still others are there to make a quick buck and will go onto other things when the quick bucks disappear.

Fortunately the bar that most people start with when it comes to eating tomatoes is low. If you start with a store bought tomato as a standard then I don't think a mouse could crawl under that bar. They decide to grow their own tomato because it looks like fun, to save money or because their Grand Parents did and buy some plants from where the shop otherwise.

As they become more interested in tomato they will go looking for other sources. Some will buy seed from places that are selling unstablized seed and will either learn or be happy with what they get. If they become more sophisticated growers they will find the better small seed sellers.

A good parallel is micro breweries. Their product isn't aimed at the person that just wants to know how cheap they can get drunk this weekend. There are also small breweries that turn out a very poor product but give it a fancy name and get fancy prices for it.

I think it all helps to drive the niche seed business.

I don't think anyone here could find fault with a seed vendor selling seeds clearly described as an unstable hybrid. You know what you're purchasing upfront. If you grow something that looks and/or tastes terrible, you haven't wasted your money and, more importantly, your entire growing season. You wanted to spin the roulette wheel and experiment from the get-go, right?

No harm, no foul. Experiments can be fun. We all took chemistry class in high school.

What isn't fun is when someone else is "experimenting" with your money and your time, without your knowledge. Or worse, intentionally deceiving you into making a purchase, based on their false advertising and lies.

Case in point. Below are two screenshots. One is from a forum, announcing the discovery of the tomato variety "Jim Dandy". The other is from a website now selling the seeds for "Jim Dandy".

Notice the date in the forum post: April 5th 2012. Based solely on what's written in the post, an unknown tomato variety cross-pollinated with a known orange variety and the resulting F1 hybrid seedling showed up in 2011. Seeds were saved from the one plant of this hybrid and were grown out in 2012.

The seeds saved from 2012 would produce the next generation hybrid, F2. F2 is an unstable generation, with different genetic traits of the parents expressing themselves in an unpredictable fashion.

In simple terms. It would be very unreasonable to expect any conformity from one plant to the next and to harvest fruits that look or taste like those from the previous F1 plant. This is why most folks don't bother saving seeds from F1 hybrid varieties. (and why you don't look identical to your siblings :P)
Reading the seed ad in the second screenshot, you'll notice the date of the F1 plants' appearance has been pushed back[B] two full years. [/B]

Why?

Because if the truth were widely known about the date of the F1 origin for "Jim Dandy", most of us here wouldn't waste our money buying unstable F2 seed. Even with pushing the date back two years, the math still doesn't add up.

The saddest part of this story is that some folks are still going to purchase these seeds and waste their entire growing season before they discover they've been duped into buying something entirely different than advertised. The innocuous-sounding "appears to be stable" statement doesn't exculpate this vendor, either.

This is not an isolated incident with Marianna's Heirloom Seeds this season. Many of their 2013 "heirloom" offerings are a hodge-podge of genetically unstable crap. [SIZE=3][B][I]

Wow, Mischka, thank you for the clarification. I visited Mariseed for the first time after seeing your original post, and followed the link to Bill's Created Heirlooms page which seemed like the right place but I couldn't find anything wrong with it. It's no wonder I didn't see the offending tomatoes, as I now see "Jim Dandy" is hidden among the regular offerings. :no:
It's even more confusing to see this done 'right' and 'wrong' on the same site.:dizzy:

My apologies to Bill Jeffers BTW if my original post sounded like a criticism of the quality of his work - I was only reasoning about the general case and did not mean any specific criticism by posting the link. I just couldn't find anything wrong with it, and judging from the other responses here, we agree on that.
The 'Jim Dandy' is something else altogether.:( You are right to post a warning for people who may be taken in.

I never claimed the pepper grow outs from hybrids to be totally stable; but compared to the grow outs from hybrid tomatoes they do seem to be much more stable even after several years. My conclusion is that they must be using parents that are not as far from the hybrid in characteristics as is seemingly the case with tomatoes. If you can't discern the difference without genetic testing then what difference does it make. I continue to plant the bulk of my peppers by purchasing hybrid seed of one or two red bell peppers that I really like. For my yellow bells and one other I will keep planting out the seed that have produced well for me from the hybrid grow out. I am not as big a fan of yellow bells or marconi types to worry if my experiment fails. One of the yellow bells has actually produced a few plants that were better tasting than the original hybrid with thicker walls so that was a plus.

I no longer try any grow outs of hybrid tomatoes because I have rarely gotten a tomato plant from them that was as good as the original hybrid. I now keep my tomato experimenting to growing out flukes from known OP varieties. One result was Indian Stripe Potato Leaf which I sent to Carolyn. It has been a very stable and unique tomato as far as I can tell and from all the gardeners I have sent the seed to. I am working on growing out another fluke from Indian Stripe that has a different color and size. I don't know if it is at all stable yet but it has shown remarkable fusarium resistance for two years now. I am going to really put it to the test this year by using it as the rootstock for several dozen different varieties. I have hopes that it will be successful but will in no way be surprised if it isn't. I have only found a few heirlooms that have consistently shown fusarium resistance but I am constantly looking for more.

Regarding 'Jim Dandy': If it is a potato-leaf variety, even if unstable for many other traits, it shouldn't be able to throw regular-leaved progeny without them being the result of a new cross... (ignoring the lower incidence of reversion mutations) since the potato-leaf trait is the recessive form.

So, a site claiming that their potato leaf variety may occasionally throw regular leaf offspring not only suggests instability, it also suggests they don't have good controls to prevent hybridization in their seed source.

Yes, your Indian Stripe PL has remained stable for me and the folks who got it from my seed offer as noted in the Fall performance thread I put up as well as well as for you. But I called it Indian Stripe PL and did not change the name, which I don't approve of since when an original RL goes to PL, there's more than one way that that can happen.

If it's a single spontaneous mutation then yes, RL to PL is usually stable, but the mutation of the DNA can also involve repeats, inversions, and looping out in which case MORE than one gene can be involved, and when that happens other traits of the PL can also change.

I think a good example of that is with at least two of the three Cherokee Purple PL's, the original being RL. I was up late, got up late andI think there's a third one I'm forgetting right now.

There's Cherokee Purple Potato Leaf, found by Jere Gettle and Spudakee, found by Bill Malin.

When folks grow out those two and the RL version in the same season, some will say they're identical and some will say that they detect differences.

IMO one should not change the name of an original RL version that turns out to be PL until and unless time shows that the two are identical and probably due to a single spontaneous mutation.

Martha, gardenmama here at Tville, found the PL version of Kellogs Breakfast many years ago now, 2002, see the link below and she called it KBX and from the link below it says aka Kellogg's Breakfast Potato Leaf but speaking just for myself I don't think I've seen anyone who uses anything other than KBX.

[URL]http://tatianastomatobase.com/wiki/KBX[/URL]

I suppose others of you can give other examples of some RL varieties that went to PL but I still feel that one should not assume that a PL version of a variety is the same as the original RL version b/c of the ways that the RL to PL can occur.

Bill, your description of your new IS sounds interesting and sounds like a cross if it's THAT different from IS, and do share what it looks like to you now, but heaven's not in this thread please.;)

I was typing my answer when you posted the above.

There could be a reversion of the original mutation from RL to PL, but only if the original mutation was a single spontaneous one, and I agree that reverse mutations of that kind are rare indeed b'c of the statistics involved in getting just ONE gene in the genome to revert.

Carolyn, who worked with mutational events with both bacteria and viruses and knew of the various DNA mutations with them, as to subsequent changes, but for some stupid reason never thought of it with tomatoes until Keith M shared that with her, so thanks to Keith for that.

As long as things are sold as unstable varieties, I don't see a terrible problem - unless you consider a crazy glut of names and crosses for the sake of crosses an issue. I buy from Tom Wagner - I like his crosses and will continue to do so - but I don't share that seed because it is unstable.

My problem with growers who cross is what I perceive as outright lying.

For example, I was given seeds by a certain someone for Sweet Beverly in winter of 2011, I planted out 30-40 plants of that and lo and behold got 4 different segregates.

I posted this on the tomato dep0t with pics in fall of 2011 as requested because no one there believed me. I have since grown it out and gotten the same segregates.

Which means to me, it's unstable.

Not only was I basically called a liar, and the whole thing forgotten, but then this certain someone came out with a "mutation" of Sweet Beverly a mere 3-4 months after I called this unstable variety to their attention, now called Sweet Sharon. Kinda funny how that happened.

Why does this matter? It matters because for those of us that really care about the craft, also care about the ethics and integrity and basically the truth about the history about what we're doing.

It's easy to re-name tomatoes, it's easy to have crosses - it happens all by itself if you grow enough. I am really, really disappointed in a few folks. It was heartbreaking to leave that community, but I did so out my conscience. I vote with my wallet now. The varieties I find to be interesting by ethical breeders, I'll buy and pay a premium for. Not so with others.

I will be posting a photo that I posted at the depot in fall of 2011 to show the segregation that included what is now known as Sweet Sharon, if necessary.

No one's perfect and everyone makes mistakes; I used to think tomato folks were kind and decent - until I found out a few weren't and then I got smart. People are people.

Don't drink anyone's Kool-Aid kids.
