Each year I try to add one or two new species to my collection of
landrace plant breeding. Last year it was soy beans. Only one non-GMO variety was available last year so I didn't get much crossing, not to mention that from researching, it sounds like they do not easily cross on their own. Still, I suspect if you crop multiple types closely interplanted and let them all dry rather than eating them fresh some crosses will show up. At least that what has happened with other things in my garden such as beans.
This year I've found three more varieties but one is already sold out so I've ordered the other two. No matter the crop, folks might want to get their seed orders in ASAP.
There is bit of discussion about soy beans over on this
thread Milion Calories. I didn't want to muck up that thread so started this one.
Concerning the discussion there, I'm pretty sure that not all soy beans are of the GMO persuasion, nor corporation owned. I've sourced my seeds from reputable non-GMO, heirloom companies and am confident they are not GMO. Additionally, I know a young man who grows hundreds of acres of beans and corn for export to Japan. Both his crops are tested and have an allowable limit of GMO contamination. If they fail the test as especially the corn sometimes does, he has to
sell them to the domestic market and loses the higher premium he gets for the exports. I don't know where he gets his seeds, I suppose it is possible, maybe likely that while not GMO his are still corporate owned.
I just wanted to offer this because soy beans are a relatively easy crop to grow and I believe contain a good amount of both calories and protein. They are also great nitrogen fixers so good to alternate with something like corn.
I worried about the GMO thing myself before planting them last year because there are a LOT of soy beans grown in my general area and I'm sure they are mostly GMO and corporate owned but there are no bean fields anywhere near my house and with their low probability of crossing on top of that, I'm confident I'm safe.
Anyway, I think soy beans might be a good garden crop for lots of people, just be careful to source good seeds. Just don't be swiping a few from that big field up the road like we used to do in the old days.
