Shortly after you posted this Andrew I reread the first post that started this thread. Darrel started this project with a full set of S. Lycopersicoides introgresion lines. Darrel, if you read this could you give us an update on your take as to the utility of S. lycopersicoides and in particular the introgression lines for cold hardy tomato breeding? How is your project coming along?
I think usually he is seen over on tomato ville in the breeding section. I got him to drop by here a few months ago briefly. I think i can only recall him mentioning his habrochiates lines. But i too am interested.
Darrel wrote the following over on tomatoville four weeks ago: "If you read some of the other threads here, I am also working on cold tolerant genetics. This is a work in progress that is taking a lot longer than I hoped."
So, sometimes something interesting comes from accidental crosses.
More often that 'sometimes' in my experience. I have several tomato selections that came out of accidents in my garden. It works out to about 1 in 3 of my bee made hybrids that turns out special. For example, I have Tastiheart which came from an accidental cross of Large Pink Bulgarian with an unknown heart. There is still a lot of work involved in stabilizing a selection out of a cross. As an interesting aside, I had Tastiheart plants that survived 22 degrees a couple of years ago. All other tomatoes were wiped out and most of the Tastihearts were killed except about a dozen plants that were totally unharmed.
Darrel, you mentioned Tastiheart in this other thread. Didn't realize it was one of your own creations.
Horticultural Recommendations: greenhouse culture; very slow stock Comments: S. lycopersicum - S. habrochaites (ex. LA1777) backcross recombinant inbred line in E6203; a high proportion of seedlings are blind. Categories: Introgression line (S. habrochaites) Accession year: 1999
They are all alive and bear green fruits by now. Like last year they flowered early but fruits take a long time to get ripe. Germination around 1st of may. First flower around 1st of June. I found another volunteer (probably a descendant of my greenhouse plants from my grandfathers variety) Germination was very late. It has green fruits by now. which should be ripe soon. It has more fruits than the other volunteers. I will reseed both types but all what matters is late blight resistance. Grandfathers variety isn`t LB tolerant.
