Restriction fragment length polymorphism (RFLP) of wild perennial relatives of soybean
Total DNA from callus tissue of 28 accessions representing seven wild perennial Glycine species was compared using recombinant genomic probes derived from G. max, the soybean. Using two probes, we show that this ...

Where are the diploid (2n=2x=20) genome donors ofGlycine Willd. (Leguminosae, Papilionoideae)?
There are about 16 genera in the subtribe Glycininae, tribe Phaseoleae, family Leguminosae. The overwhelming reason for the economic importance of the subtribe Glycininae is due to the cultivated soybean,Glycine ...

Adventitious roots inGlycine subg.Glycine (Leguminosae): Morphological and taxonomic indicators of the B genome
Adventitious roots were observed on 3 wild perennialGlycine species, in short-poddedG. clandestina, G. latifolia and mostG. tabacina (2x, 4x, 6x), while other species lacked adventitious roots. This suggests that...

The inheritance of a urease-null trait in soybeans
Four soybean seed urease nulls (lacking both the activity and antigen of the embryo-specific urease) were intermated and the F1 and F2 seed examined for urease activity. Both generations were without urease activ...
