I was under the impression that the flowering time for many more temperate inbreds (as well as the extreme northern varieties like Flints) were determined solely by total days or "growing degree days," so temperate lines should, in fact, successfully reproduce in the tropics (although they'd flower too soon and miss a good portion of the growing season). However, I haven't done the experiments myself and I can't seem to turn out any papers to back this idea up in a quick search tonight, so I am completely prepared to acknowledge I may have gotten this wrong.

Just to elaborate - modern cultivars haven't really lost it, just the big exhibition of leaves. Less-reactive modern cultivars are commensurately geographically limited in reproduction; now they can't reproduce in the tropics - no wider range for them but rather for the maize subspecies! “Mexican corn determines when to flower based on the length of night, a trait that modern cultivars have lost, allowing them to successful reproduce at a much wider range of latitudes.”

Keep it up! Here's a link to the interview they did on KVAL @ strawberry genome featuring some of the players from OSU and USDA in Corvallis. http://www.kval.com/news/business/112533799.html I am sending you an invite to a workshop we are hosting at PAG, hope you can attend.
