Strains HH103 and NGR234 Form Nitrogen Fixing Nodules With Diverse Wild Soybeans () From Central China but Are Ineffective on Northern China Accessions.

indigenous populations are prevalent in provinces of Central China whereas species (, , , and others) are more abundant in northern and southern provinces. The symbiotic properties of different soybean rhizobia have been investigated with 40 different wild soybean () accessions from China, Japan, Russia, and South Korea. Bradyrhizobial strains nodulated all the wild soybeans tested, albeit efficiency of nitrogen fixation varied considerably among accessions.
