Isolation and properties of soybean [Glycine max (L.) Merr.] mutants that nodulate in the presence of high nitrate concentrations.

Soybean seeds [Glycine max (L.) Merr. ev. Bragg] were mutagenized with ethyl methanesulfonate. The M(2) progeny (i.e., the first generation after mutagenesis) of these seeds were screened for increased nodulation under high nitrate culture conditions. Fifteen independent nitrate-tolerant symbiotic (... View More
