Who's working on earliness?

[dice]

The symbol "F1" means it's resistant to fusarium wilt, race 1, according to their website.

Not a really useful abbreviation to expropriate, since it is almost
universally used to mean "first filial generation" by plant hybridizers,
but looking at other listings there, that seems to be the case at Territorial.

My question about the research would be whether the quantitative
loci for earliness and size found in Early Cherry are common in cherry
cultivars in general. Many of them are early, and they are by definition
small sized.

For size, I would think one would want to compare Early Cherry with
a number of small-fruited cultivars, early, mid-season, and late, and
see how many share those same genes. (Is there anything really that
special about Early Cherry in particular for hybridizing?)

Same thing with earliness. There are few large-fruited varieties with
DTMs in the 60-65 days from transplant range, but there are numerous
saladatte and "mid-sized oblate" varieties. How common are these same
genes?
