Any guesses?

Alright,early this season when my plants started flowering I took some good pollen from my sbg cherry tomato and fertilized two flowers on a healthy chefs choice plant.the chefs choice is a golden tomato hybrid.large golden fruit.info says the ammana Orange is one of parents.any ideas what the seeds may produce?they both took and are growing normally.

I don't even know the colour of sbg cherry or Chef's Choice, but one thing for certain, if one parent is a hybrid then you will have genetically different plants in your F1 generation, so each seed that you obtain from the cross is potentially unique.

Also since small size traits in the cherry parent are dominant, your F1 generation will all be cherries or small fruit.

Both plants are hybrids.the sweet baby girl is a red cherry,the chefs choice is golden color fruits.

Red is dominant to yellow, so all of your F1 generation will be red fruited - assuming that both parents of the hybrid SweetBabyGirl are red, and assuming that "golden color" is yellow. If so, all offspring will have Rr genotype and the red colour will be expressed.

If the "golden color" is orange, it depends on the gene involved - there are several different genes that produce orange fruit. If the gene is 'tangerine', both parents must have the t allele for it to be expressed in the hybrid Chef's Choice, whether they are RR (red) or rr (yellow). The F1 generation will still all be red, since they're getting one R allele from sbg, which is dominant, and tT tangerine will not be expressed.

If the "golden color" is a Beta orange, then both parents of chef's choice must have BB and RR, because Beta is not expressed in rr fruit. The F1 will be orange-red.

So chances are good that your F1 fruit will be red cherries/ small red fruit. In the generation afterwards, you will find approximately 1 yellow fruited per four plants if a simple red/yellow cross or one orange fruited per four plants if the 'golden' is tt tangerine.

Awesome.thank you for the info.

You're welcome.. hope you have fun with your cross.

Bower, Chef's Choice appears to me to be tangerine gene hybrid (t/t) rather than yellow fleshed (r/r), if that would make a difference. I may be mistaken, but that's what it looks like to me (I grew one vine this summer as a trial).

Kongo, if your crosses took and produces true F1 seeds, and regardless of the F1 color, I estimate your F1 fruit will be round and approximately 1.5 inches or so in diameter, and weigh about 1.5 or 2 ounces max.

Did you emasculate the two flowers on which you transferred the pollen? And if so, at what stage of flower maturity did you remove the male parts from the receiving ova?

[Kongobongo]

Yes I emasculated them.the flowers were completely closed,still green.then I left them overnight and pollinated early next day and then the day after.I also clipped off the neighboring flowers.I'm no expert whatsoever just learning.

The second day I could actually see the pollen sticking to the end of the pistil.

Cool... afaik tt will express in either red or yellow background. I grew several tangerine OP's this year, identified by flower colour, and all of them ripened orange which I couldn't tell apart by the shade. The only difference, Bursztyn which is described as 'orange-yellow' ripened yellow first and then turned orange, so I think that one is a yellow-tangerine. If Chef's Choice is a red background tangerine, the ratio of orange in F2 would just be 1/4.

I'm not sure whether tt will express in a heterozygous Rr condition, although I think the information is in one of those papers on colour genetics. I vaguely remember that there were subtle differences of shade they couldn't tell apart in heterozygous red/yellow background fruit, so if Chef's Choice is a yellow tangerine, you'd get 1/4 F2's in some shade of orange.

If not though, the expected ratio for tt RR would be the same as for tt rr which I believe is 1/16, so putting both together you'd get 1/8 some shade of orange.

Up for work and checked on three fruits i am ripening in the cupboard,they are a dark yellow.I'm sure they are ripe.it's funny because it's advertised as Orange.cut in half bright yellow.they are off of one plant.I have 5 more,maybe some will be Orange from the other plants.

[bower]

I guess if they turn orange when they are completely ripe (or over ripe?) it would indicate a yellow tangerine - tt in a rr background.

If you still have flowers on your plants, you should be able to tell.. There's a thread on flower colour in the Crosstalk forum, with pictures from a scientific publication as well as my own pix of the anther colour of tangerine tt flowers. Deep orange as soon as they open - it's quite noticeable.

Today, I will check the stamen color on my single vine, and then report back later this afternoon.

The Chef's Choice fruit does ripen up very slowly, as if maybe the rin is present, so I picked them early when they appeared to be ripe yellow flesh; but when left to ripen fully indoors, they sliced tomatoes appeared tangerine fleshed. This observation is totally based on my 67-y/o optic nerves (with developing cataracts) :::smile:::

Edit: What I really wanted to say is that Chef's Choice looks to me like an indeterminate knock-off of the much superior, determinate F1 Carolina Gold, which I have grown many times in F1, F2, and F3 examples. More to the point, Chef's Choice enjoys great plant health, but the fruit is prone to radial cracking in wet weather (although it seems to resist cuticle cracking and concentric cracking), exhibits puffiness in dry hot weather, tends to be a bit "grainy" textured under stress, with uneven color development generally, and just not as flavorful or highly t-colored at the superior Carolina Gold, which most definitely is an unmistakable t/t cultivar.

Follow-up: Kongo, the cross to your sweet cherry tomato surely will improve the Brix content and hopefully the flavor of Chef's Choice, and you might get some dandy orange cocktail saladette size tomatoes in the F2s and F3s. Go for it.

[Kongobongo]

I agree.very,very nice to look at,bright yellow,no flaws at all but when I ate it,the inside was...well mushy.and for sure it wasn't over ripe.a little disappointed.mushy texture.I did the cross before I had even tasted the fruit.simply because I found it fascinating.but I've started and will try and see it through.I owe it that much now.
