There are a couple other breeding possibilities that intrigue me with favas...
1- selecting for more winter hardy strains. (I have had plants survive the winter in usda zone 5, but they then succumbed in early spring). I am able to plant favas in November, and they send out a tiny root in the fall, and sprout in the spring when they are ready. This fall, I planted favas every couple of weeks, so some went into winter as small plants, some went into winter as barely emerging, and some went into winter as seeds. My goal is to select for more cold tolerance.
2- I could put effort into selecting for strains that could thrive when transplanted in early March. That's give them a month headstart on the growing season.
3- I could select for strains that could be planted mid-summer, and that would produce pods/seeds for fall harvest.
4- Sometimes, after the spring planted favas have produced beans, they re-sprout vigorously from the base of the plant. I have often thought that selection for that trait might be worthwhile.
5- Selecting for productivity (pounds per square foot)
6- Every once in a while, I see a seed with eye-popping color. I haven't been selecting for those traits, but it could be done.
7- Like with every crop I grow, I am inadvertently selecting for ability to out-compete weeds, and to grow in a super low-humidity environment, in full desert high-altitude sunlight.
Anyone who wants to OSSI-pledge a derivative of my fava bean landrace wouldn't receive any objection from me, just give it a different name.
