GOB15 crosses

frogsleap farm · August 7, 2011

GOB15 is a late blight/early blight resistant hybrid developed by Randy Gardner. It is similar to Plum Regal in plant/fruit phenotype, but with better disease resistance. GOB15 was crazy prolific but typical of most paste types, not very flavorful. I made several crosses to this last year and was able to get F2 seed produced over winter in Hawaii (thanks Dan). Here's the first ripe F2 fruit from the cross GOB15 x my (SunSugar derived) best striped cherry breeding line. The flavor on this was 9.0, with a definite tie to it's grandparent - SunSugar. From this series of crosses I'm hoping to develop some tasty lines with better disease resistance.

A good shape with flavor - that's what we need here.

Here are two more. The beautiful fluted fruit is from a F2 plant from the cross GOB15 x (Dora x PBTD). It appears to be heterozygous for gs. The second photo is a F2 fruit from GOB15 x BTD heart, also probably heterozygous for gs.

Looks nice. just gotten around to growing a few. Have a plant of the gob15xss that is absolutely monstrous, exceptional vigor.
were having a good weather spell here now so no blight to test against can't say I am complaining about its absence.

This monster is from GOB15 x BTD heart.

Nice looking fruit....

But, how do you confirm that you got the disease tolerance in the crosses? I'm guessing that's the hard part!

I grew Plum Regal this
year and was absolutely floored by it's disease tolerance and productivity. This plant produced 33 pounds of fruit! (My typical is 5~6 with 10 being a great plant). The only reason it went down was due to spider mites, not disease.
However, the flavor is just not there at all for this one. Even cooked
down, it is not great unless combined with a couple other varieties.

I'd love to have this disease tolerance with better taste, but I'm guessing that's a way's off....

Keep us posted and thanks for sharing!

After my last post I observed LB. I had some resistant lines. The gob15 crosses went up in smoke in a matter of 3 days unfortunately along with golden sweet which is advertised as being resistant to LB...its not. again what a nasty pathogen its vigor always surprises me.

Bummer Dan. What looked good? I think GOB15 is an improved Plum Regal. I had them both in 2010 and they were pretty darn similar. Based on what I learned from Randy Gardner, GOB15 had LB resistance on both sides of the pedigree, vs one side on Plum Regal. GOB15 was also a productive son of a gun, but not much flavor. These F2 selections have much improved flavor.

I think the resistance should show up in the f3? I have devised maybe a slightly better way to mass test than last time. I did not grow out much of the f2 at all.
If the plants were a little larger I think they would stand a better chance of showing any resistance they may have.

A couple of more F2s from crosses with GOB15. A very meaty bicolor and a nice striped purple plum.

Wow!!!! What a beauty!! Do they all look that stunning. How about the flavor so far. Hope you get it sabilized to look like that with great flavor, I would be first in line to buy seed for a variety like that. Awesome. Not grown many stripes, but planning on several varieties for 2012.

Those are some really beautiful looking tomatoes! Looking forward to hearing more about the next generations.
