I am in the process of crossing colors that I have not done in the past and want to know if anyone has information on what the F1 hybrids will be color wise. The crosses I am interested in involve the following colors crossed in all possible combinations: yellow(r gene) tangerine(t gene) Chocolate Stripes (I am assuming this is considered a black tomato) Green-ripe (Malachite Box variety) Beta Blue fruit bi-color (yellow/red streaks from Mr. Stripey) Some of you have probably done at least some of these crosses and can tell me what the F1 hybrid colors are. Thanks, GOBmaters

One I know for sure is Green x yellow. A cross of Green Giant(green ripe) x Yellow Submarine(yellow flesh) by papavic grown last year resulted in the F1 fruit being yellow.

Thanks, mulio. I thought that you would probably respond to this based on your experiences. I have noticed the same faint striping in the F1 of a red tomato x Chocolate Stripes. This expression in the heterozygote will be a good marker for selecting plants that will segregate for stripe in the next generation, which I have an interest in. Crossing colors will be very interesting because of the potential for developing tomatoes with unique combinations of the different colors combined with clear skin effects and will give some interesting combinations related to texture and flavor based on the differing flavor components in the different colored varieties. I did not mention but also have clear skinned red(pink) and crimson in this crossing project. GOBmaters

Mulio - have you seen any negative phenotypes associated with the hp mutants? I've seen some reports about poor seedling vigor.

I did not mention but also have clear skinned red(pink) and crimson in this crossing project. GOBmaters JayTee already mentioned the Green Giant (gwr/clear ep.) x Yellow Pear (yellow flesh/yellow ep) cross I did. He, I and a few others grew the F1 this summer and of course got the expected golfball size, yellow flesh with gold appearance due to yellow epidermis: Would anyone care to comment on the F1 fruit size generally running in the neigborhood of the square root of A + B? One grower in Texas grew out a couple of F2 plants during her second crop this summer at luckily got a clear epidermis example, but still generally of the golfball shape and size. Her other F2 also was the same shape and size generally, but had the yellow epidermis. Since both parents are potato leaf, all vines have been PL in all cases, of course. I'm hoping for someone to find 1) a green grape PL and 2) a green pear PL. Those were my goals. DarJones and Mule tell me the odds are long for both. I posted this message in this topic due to the green when ripe and epidermis color comments. Hope it's relevant. Bill

Probably more relevant to Gobmater's original post might be two of the other crosses I made two years ago: Cherokee Purple x Bradley and Indian Stripe x Sun Gold. Cherokee Purple and Bradley are both clear epidermis, "pink" tomatoes with Cherokee Purple being one that retains chlorophyll for that maroon or brick reddish pink that I suppose relates to its designation as "purple." DarJones and Mule both told me what to expect and that's exactly what I got ... a slightly flattened, deep pink globe with clear epidermis but no chlorophyll retention in the F1: Frogsleap grew the F2, as I think JayTee may have too, and reported a "purple" recombination. I plan on growing the "purple" F3 this summer for a looksee. The other cross, Indian Stripe x Sun Gold yielded a large, crimson red cherry on an extremely aggressive vine with foliage that smelled like the Sun Gold parent. As a side note, the aroma of the vine or something about it was a whitefly magnet. I did not spray insecticide of any kind and the only resulting damage was little pinholes in the foliage with no apparent side effects. Again, both Frogsleap and JayTee have grown the F2s from the Indian Stripe x Sun Gold cross and Gobmater might find those more interesting color recombinations than the ordinary F1 crimson I got. In the F2, I got a bronze, a red, a pink and a grassy green ... all cherries. I'm asking Jaytee and Frogsleap to post pictures of their recombinations because I failed to take any photos of this one. Thanks, guys. I do have photos of the F1 because I took them to show the tendency to burst carried over from Sun Gold. If you pick the fruit slightly earlier than full ripe, this is not a problem: So, that's the F1s. Some of the F2s show a more "mini-beefsteak" shape. Jaytee, show Gobmater your F2 color recombinations. You too, Frogs. On this one, my goal is a saladette (2 - 3 ounce) or larger (hopefully like a 6 - 8 ounce salad tomato) with some unusual color recombinations. A variety. Bill

Jaytee, show Gobmater your F2 color recombinations. Bill I had two plants giving above average tasting fruit. Both similar colors with yellow epidermis and whatever color flesh that is...but the flavor of the cherry-sized fruit in the second picture was tremendous. As good or better than sungold.

Thanks Mulio. Bill, I'll post photos of IS x Sun F2 tomorrow.
