OSU Blue observations

Wow, very nice Lee!

[DKelly]

Cool Lee! does the currant posses any magical powers against diseases?

[dustyrivergarden]

This is just insane. You guys are awesome I love this. I have been on this forum just over a week and everyday I am floored. Very cool guys keep it coming....

Just found this Googling something that didn't have anything to do with blue tomatoes but thought some might think it's interesting: http://www.gmwatch.org/latest-listin...to-beat-cancer

The link title is a misleading, but the gist of the article is that some Brazilians have created a blue tomato. Doesn't really get into specifics, but if somebody knows any Brazilians that grow tomatoes maybe we could get some more blue tomato genes into the fold.

frogsleap -

Here are some seedlings of the speckled blue I started. They show the color on the leaves as well, but that is washed out on this photo. Good to get things going, though the wind is bitter cold today and it doesn't look anything like spring yet!

Goodwin, that particular blue on the stems is from the atv gene.

atv.....good to use for technicality, but poorly remembered even by myself. I just say blue vine or green vine.

My variety Blue Angel..out of seed...has blue tomatoes on a green vine, whereas Out of the Blue has red tomatoes and a blue vine.

Keeps it simple ....Dancing with Smurfs is blue/blue

Dar - yes, it is presumed to be homozygous AftAft atvatv. However it shows a variegated appearance so there is something else going on here.

[frogsleap farm]

Certainly anthocyanin in seedlings (especially in the hypocotyl of young seedlings) is not strongly correlated to anthocyanin in fruit. But I think strong anthocyanin in fruit requires homozygous Aft and atv. In segregating populations I always select first at the seedling stage for homozygous atv, because it is a clear phenotype and it's simple. In addition to Aft and atv there appears to be other genes with a secondary effect on anthocyanin fruit - but that's still a mystery .... at least to me.

Here are the first fruits on the Bosque Blue. I have them in 5 gallon buckets which I move in and out of the greenhouse now. There are other things setting like the Pearly Pink Orange, but this is still quite early. The P-20 ( Indigo Rose) plants are showing a lot of leaf roll for some reason, but I am reluctant to pull them because I would like to see what the fruit looks like. Meanwhile I spent the last week setting a lot of other varieties out in the garden with the unusually warm weather. Happy Easter everyone! Lee

Very nice photographs, Lee. I love how neatly you have your wall 'o waters set up. I had some leaf curl on my indigo rose seedlings, but I really think it was temperature related because when the temps became more stable in my classroom, they ended up fine... I could be wrong about the temp hypothesis, but it is my best guess right now.

[goodwin]

hi Jennifer -
You are probably right about the temperature and those plants are more susceptible. Not just the leaves are rolling, but the stems are twisted as well.
And the wall of waters do pretty well protecting the plants - now if they would just set themselves up! This bunch will have the larger varieties I save for seed. Anyway, it feels great to start another year.

[frogsleap farm]

I've noticed considerable leaf roll on a number of my P20 - derived Aft lines, and on a couple Aft lines I tried from Tom Wagner last summer. I think there is a genetic linkage of the two traits. Several of my Aft lines do not show the linked traits, so the linkage is not that tight - non-linked segregants are fairly easy to find.

[goodwin]

frogsleap - what you are saying agrees with what I've seen. Fortunately, the trait hasn't appeared in the lines I've been working on.
The plants from the seeds you sent me look fine. I'll post some photos of those when they get a little further along. Here is one of the Indigo Rose plants with the problem.

I have 3 OSU blue plants : 2 of them are green with bluish stem, and one has leaves getting blue hue in sunlight. Should I collect seeds from that "tanning" one?
