Am wondering how difficult it is to make your own bi color? What are some of the first basic steps? Thanks.

Super easy. Any cross that invloves at least one bicolor parent will produce bicolor offspring.

Agreed. Use a bicolour as one of the parents and then grow out quit a few F2 plants. You should find a bicolour or two among them. The more F2 plants you grow, the higher the odds of finding something you like. Good luck

And an example
http://tatianastomatobase.com/wiki/Orange_Russian_117 The deliberate cross by Jeff Dawson was between Russian 117,which is a large red heart and Georgia Streak,which is a bicolor http://tatianastomatobase.com/wiki/Georgia_Streak ... and then grow out saved F2 seeds to start with and then make selections and keep doing that until you have something genetically stable. It can take several years to do that. Carolyn

Thanks for the replies everyone.what I really meant is to start from scratch with no bi color parent.do you just cross two colors and keep growing out the seeds in hopes of finding a mix color somewhere?that's what I'd really like to try.

Without the 'bicolor' gene, you'll never get bicolor offspring, just a segregation of solid colors (though you can get colors "in-between" the original two).

What (bi) color combo are you hoping for?

https://www.google.com/#q=genetics+o...tomatoes&hl=en Last I knew the genetics of bicoloredness was not known in it's entirety, but I could certainly be wrong. Paddy,you speak of a bi color gene,does it have a name,or are your comments based on observations of all the wonderful crosses that you have made? Carolyn

I just wanted to use what I have.yellow and red.I thought a bi color must have come from a mix of two colors.sounds more complicated than I thought.

Cherokee Bi-Color! (Cherokee Green was one parent, the other parent was NOT a bi-color!

Based on it's coloring, I think Cherokee Green may be a subtle bicolor, and that the bicolor trait is enhanced when a yellow parent is combined with Cherokee Green.

Cherokee Green certainly seems different from the other GWR varieties I have grown. I think of it more as a yellow tomato with zing. Maybe it's a green and yellow bicolor?

Another segregate from a Cherokee Green cross...
It ripened fully from the first pic to the 2nd if you waited long enough! Last edited by korney19; December 18, 2016 at 12:39 AM. |

You get things happening above when you save seeds from fruits like these...
