Link to Alan Kapuler's article on ocassionally out breeding tomatoes. I remember back when seeds of change was cool and independant Alan was their plant breeder.

I grew Alan's Golden Tressette for the first time this year. Of course their was some variation with and without a blue blush. It was exserted of course.

Joseph Lofthouse developed his Big Hill tomato in this vein. Looking for open flowers. It is reliably so.

Exserted flowers is now a trait I really look for in my garden. Joseph wrote about it and got me started looking. I'm finding it to be a handy tool, just look for the hybrids, then save seed and look for the segregates that have exsertion. Nice to have a few packets of the F2's marked as exserted. I'm sure they'll lead to future discoveries.

Joseph has a even bigger plan with self incompatible tomatoes. I think it will work too, but the exserted trait is handy on its own now.

Thank you for that article.  Last year I grew lots of dwarfs and all the late blight resistant types I could buy with the intention of crossing them.  I didn't make any crosses.  If I still had the eyesight I had when I first hybridized 70 years ago, I could do it easily.  So next year, I'll grow hypertresses  snuggled up close to LB resistant ones and dwarfs and  let the tomatoes cross themselves.

I worked on a farm this year that grew lots of Johnnys tomato varieties and I noticed that a lot of them had exserted stigmas. I don't know if the varieties were specifically from the Johnnys breeders but, whatever the source, it seems they used the exserted trait.

The varieties that certainly had exserted stigmas:

- Prudens Purple
- Pink Berkeley Tiedye
- Striped German

These are all rather large, long season varieties but figured I'd list them for later reference.

I was fairly impressed with my one Lizzano F2 plant for shortness of season. Would like to cross it with Big Hill perhaps.
