Gai Lan and deteriorating Brassicas
The Vegetable Gardening forum has a current Gai Lan thread. I am reprinting my last post here, since I want to know about specific Gai Lan cultivars and whether other people agree (or not) about my comments about the deterioration of some other Asian Brassica cultivars.

I don't think that my most recent sowing of "Blue Star"has germinated yet. My recollection of my late fall sowing was that some seedlings were vigorous while many others were stunted. I would plant each pot with about 6-10 seeds and thin to about 3 of the most vigorous seedlings (later down to 1).
Cultivars of Brassica, need to be under yearly reselection, culling out the weak, and growing enough individuals to maintain genetic diversity via cross pollination. My impression of "Blue Star" is that the cultivar is deteriorating. But then again, maybe my memory is faulty and I'm remembering some other Brassica.
Now that I just tasted Gai Lan a few months ago, I now have the "Gai Lan Bug" and want to try some other cultivars. I want to know what variety is giving you germination troubles. Evergreen has 6 Gai Lan cultivars, Agro HaiTai has 3, and Johnny has 3.
A couple of other Asian Brassica cultivars that show variable seedling vigor (at least in my hands) and could be deteriorating genetically are "Misome" and "Hiroshimana".
