As a rule, soybeans do not need very wide spacing for seed saving. I generally use 20-30' between varieties, but can space them as close as 10' apart if they are in different Maturity Groups & have other flowering crops between them. I try to separate group 0 or Group I varieties, with a Group 000 variety between, since they will usually begin flowering at different times. I also try not to grow two varieties of the same seed color, and/or flower color, in adjacent locations... so if a cross occurs, I can catch it quickly. Like common beans, soybean flowers are usually either white or purple - and very small. I've seen bees working the flowers, but with the measures mentioned above, crossing has been uncommon.

Sounds doable then. I have a lot of space, I can certainly accommodate that distancing. I’m already growing Midori Giant Edamame.

I believe that is the same as Sapporo Midori, which I grow... the "giant" probably refers to the large seed size. Sapporo Midori is Maturity Group 00, which would have no problem maturing in your area. If my hunch is correct, that helps me to decide which other varieties are best grown in its vicinity.

Not wanting to hijack Russ's thread...

Soybeans are not as glamorous as beans, and not as many gardeners have a use for them... but I try to offer a wide selection (68 accessions at present) to other gardeners who are interested. Some are edamame. Others are intended for processing into soy milk, tofu, or other products - and there are few commercial sources for non-GM processing soybeans. Most of my soybeans came from the collection of Robert Lobitz, who in turn had obtained them from the USDA; they hale from many different nations.

The problem is that my collection is getting perilously old. Several very wet years - two of which broke consecutive records for precipitation - caused crop failures, or prevented planting entirely. As a result, I have lost so much ground that I may not be able to replenish seed stocks before they die in storage. These are the varieties currently at risk:

I will try to post some photos soon.

The table didn't transfer well, which is the reason the columns wander a bit. The bizarre thing is that I spaced columns manually after the transfer - and they still show that way when I edit - but all extra spaces are eliminated when I save. Which undoes about 15 minutes of work... :he Any advice for fixing this jumbled mess is welcome. Is there a way to set tabs?

The protein & soy percentages are from USDA GRIN data for those accessions. The soybean Maturity Groups are relative maturity; 000 is the earliest (up into lower Canada) followed by 00, 0, then Roman numerals I, II, III, etc (up to X, which is tropical). Each successive Group is 10 days later than the one before. Because soybeans are photo-period sensitive, the actual maturity will vary depending upon latitude. As a rough frame of reference, here at 44 degrees North latitude, Group 000 will be about 90% dry for me in 90 days plus or minus. So Group 00 would be dry in about 100, Group 0 in 110, etc. My location is borderline for Group II (130+) which can be hit or miss, depending upon my frost date.

TEG has a vibrant seed-saving community, so I'm hoping that we can start a soybean preservation project. If anyone is able to grow a soybean or two, I would be grateful for the help. I would send the variety(s) of your choice, and ask that you return seed to me at season's end. If there is interest, I would be happy to post further info. Places that once offered heirloom soybeans retail (Victory Seeds, Synergy Seeds) are dropping or reducing their offerings, and I may be one of the only sources left; so I hope to get some of these into other hands.

i can try a few each year but i can't promise results with the creatures we have here. knowing that you usually have large amounts of seeds it may be worth a shot. :) sign me up for 2021. :) i'm all booked for this season. repost a new thread in the winter when we're all sitting around waiting for the winter to end. pictures. pictures... :) :) :)

i will be trying the one you shared with me at the seed swap so if those do ok i can have some fresh seeds from those in reserve.
