You’re spot on and have those color genetics down Bower! Both F1 are on the right, pollen donor on the left. And after posting this picture I see a couple leaves that needed removal!

Your plants look great and the Beta/- fruit color is yummy! :cute:
(What I hate is finding pics of aphids on my fruit, three days after I took the photos! :shock: :panic::?)

Excited to pick the first fruits! Both plants yielded fruit today—98 days from seed, 53 from transplant.

You know,it was posted before by me,that I was lucky enough to first offer both of your tomato parents re seeds in seed offers, so I really am looking forward to what comes out of this cross,which ones you will select to go forward with genetic stabilization, etc.

And of course which selections have the best fruit tastes as well, in your opinion.

Thanks Carolyn, those two are incredible varieties and they have yielded one heck of hybrid tomato! Plants are great and full of fruit, but tonight we did a side by side with the F1 and JF. The F1 has the bright delicious tangy tomato flavor of JF, with some added sweetness from CY. Similar texture, plenty juicy, which I prefer. I’d put the F1 right at the flavor level of JF, maybe ever so slightly just below. I’ll need to taste more fruit at various ripening points. I’ll have no shortage of fruit to taste and F2 seed. F1 are the larger, more red-orange fruit.

Another shot showing differences between F1 (front) and JF (back). Had these at my desk for lunch and noticed the lighting showcased the subtle differences well.

Fun to see the color differences side by side. Can't wait for reports on next year's grow out. I find my JF plants get pretty tall 8-11 ft. Were your crosses tall as well?

The F1 is quite tall, longest vines are probably ~8ft. August was rainest month here, both in amount and frequency. When the rains finally let up most of my tomatoes were pulled due to extreme defoliation from fungal disease. a good month earlier than usual. The F1s are a couple that remain and will continue to at least ripen up a few more fruits. I grew the F1s next to JF this year. In my garden, The F1 had longer vines than JF, more like the CY mother.

I'm very excited for the F2!

A cross with exciting potential. Well done. A good number of years ago I too was so taken with JF (still am) that I thought pretty much as you did and crossed it with Paragon, the only good-sized tomato in the garden at that time. As is often the case, life had other plans and I found myself gardenless for a good few years so the project evaporated.
I look forward to tagging along as your journey progresses.

These were planted out today. 3 F2 from plant A last year and 2 F2 from plant B last year. Also growing a F1 for comparisons. I don’t expect differences from plant A and B since they were F1, but grew some of both anyway. Just expecting regular F2 segregation.

Jm those fruit look so juicy and amazing....
Looking forward to see your F2s. If you are hoping to get the CY size back you may need to grow a few more as the size distribution tends to skew towards smaller fruit. I'm sure they'll be interesting, regardless!
Oh the juiciness... :love: I could just taste those.

Thanks bower! I view my F2 grow out as a multi year venture due to lack of numbers. Size would be great but flavor is number one goal. I’ll follow anything with outstanding flavor into the F3. Ideally a Jaune Flammee in the size of a baseball would be a jackpot hit in my view.

Dr. Carolyn "who I call Miss Carolyn" will be so proud of you, Amen!!!

Healthy plants, flowers have opened on 3/5 of the F2 (2 yesterday, 1 today) and the F1 (today). Plants all have very similar habit, shape and size in the F2 thus far. Flowering is late this year due to a cool May.

One of the F2s has a flower cluster bordering on multiflora. Obviously no MF in the genetics and likely not every flower will set fruit. First flower clusters on the F2 have a variety in the number of flowers.
