Sugar Magnolia
Here is a tomato that I am trying to stabilize from a cross made between two of Dr. Randy Gardner's originals.
One of Gardner's crosses was Brandywine x NC 1-CELBR and the other cross was Malachite Box x NC 1-CELBR. NC 1-CELBR is a red fruited, Early Blight/Late Blight resistant breeding line from North Carolina State Univ.'s breeding program. I crossed one line from each of the two crosses that I had been growing out from seeds I obtained from two Southern growers. The Malachite Box line I used was an F3 green when ripe, regular leaf, semi-determinate with a red blush and some red interior streaking. The Brandywine cross was a pink tomato, F4, potato leaf, with excellent flavor. I am still getting both potato leaf and regular leaf plants, and the fruit coloring is relatively stable at bicolor, although I still get some clear epidermis and yellow epidermis variations. There also are slight variations in flavor intensity, although those variations may be more associated with weather conditions during the ripening process. I had planned on letting these seeds out as Sugar Magnolia, but have now decided to grow the lines out a few more seasons before deciding on the RL vs the PL lines. I also would love to capture a semi-determinate out of these crosses, but all have been relatively compact but fully indeterminate at this point.

I'm not so sure I'd call what you have a bicolor, yes, the internal pink blush would be not atypical for a clear epi close to white but other than one side of the twin one showing some pink, and apparently not from the blossom end as it should be, for a typical bicolor, the ones in back shows nothing. Just been through this with someone else, not here at Tville, about Lillian's Yellow Heirloom. I'm so glad that now in retirement you have the time to do what you want to do, which is breeding tomatoes, but with all the lines you are working on, not just the two you mentioned above, where do you find the space to do those growouts, or do you farm them out for others to help out? Carolyn, outside temp 94, inside 79, high humidity, not used to that here, but better than the time the firs thard frost killed my plants on Sept 7 one year and the next year on Sept 9.

I do not know whether what I show is a true bicolor by genetics. I do know that one parent was a bicolor green when ripe from the Malachite Box x NC 1-CELBR cross. I've gotten several variations of green when ripe flesh (which simply is yellow flesh stained with retained chlorophyll) ... everything from what looks like Cherokee Green in exterior appearance, to rusty copper exterior colors, to dulled red exterior with gwr interior ... all with gwr interiors, some with red streaks some just with a red blush, etc.
The other parent was a pink line from what was sent to me as "red" from the Brandywine x NC 1-CELBR cross. I got reds and pinks from those seeds. I've gotten regular leaf and potato leaf from those seeds, etc. So, I am assuming the yellow flesh comes via the Malachite Box background, the potato leaf comes via the Brandywine background as most likely the clear epidermis does, and the red blushes and red streaks or whatever may appear as bicolor in the core or in the pericarp comes from either Malachite Box or some other genetics about which I have no clue. |

(some other genetics about which I have no clue.)
Having no clue has increasingly become my default answer when trying to answer some of the questions here at Tville. Carolyn

Carolyn, I'm hoping you are enjoying the US open! Maybe that is why no clue is your default answer

I started to watch Serena and her sister play last night but every time an ad showed ESPN3 went kinda bonkers. The women's final is on Saturday and I really hope that Serena wins and makes history and she should make to the Final b'c her next opponent is Roberta Vinci from Italy and as one unkind person posted Serena could beat her even if she was in a wheelchair. The men's final is Sunday and not for sure yet, but maybe Djokovic and Federer but also Wawrinka and Cilic to think about. And my to do list here at home is getting longer and longer, without me being specific. Carolyn, just happy to get her DSL line back since it was out until about noon yesterday, Alert, alert for Bill. I can no longer see your pictures and I don't know what that is all about.
