(Opalka x My Brandywine) x Bianca Grande
I don't have a name for this line yet. Opalka is a really nice paste tomato - low moisture, low seed count, rich flavor. Brandywine is all about the flavor, and my selection has great production and good fruit size. Bianca Grande is a cool white with great sweetness. Originally I was envisioning a very low moisture, low seed count, large size, great tasting white. I was thinking white sauce with taste. And in the F2 I got a very big white beefsteak with great production.
Now at F3 I got no whites, but I don't care any more because I got some lovely, productive, tasty yellows and oranges! 7-1, 7-3, 7-4. 7-1 gets the nod going forward due to it's great taste and low seed count. It's a bit "oranger" then the pictures make it look. 7-2. Very subtly bicolor K 7-3. The white-ish one. Last edited by PaddyMc; October 11, 2014 at 12:19 AM. |

Which F2s did you use to parent the F3s? I was under the impression the white trait was driven by recessive alleles, such that whites would be expected to recur in the F3 if they were selected in the F2.

I've also been at this tomato breeding game long enough to think that the "hard and fast" rules about gene dominance in tomatoes ain't so hard and fast! For instance, I've had lots of lines with either stripes or antho at F1, in crosses where those (supposedly recessive) traits shouldn't have shown up until F2. |

What you've described sounds like it tells a different story. My impulse would be to grow out a lot more F2s and F3s (from the white) until I could understand what was going on… but I have a compulsive need to solve puzzles that you may not. Quote:

I wrote up a blog post about my thoughts and observations (http://the-biologist-is-in.blogspot....ue-tomato.html). I need to grow out more F2s to get a clearer idea of what is going on and for now I want to keep this my personal project.
