摘要：
Seed of white bean (Phaseolus vulgaris L. cv. OAC Rico) was treated with 0.04 M ethyl-methane sulphonate. Screening of the M2 progeny from 175 M1 lines in the presence of 1 mM nitrate revealed two nodulation mutants. One line was essentially non-nodulating in several tests, but small white nodules were observed occasionally in other tests with 16 separate Rhizobium strains. The other line formed tiny, creamy white, non-functional (ineffective) and tumor-like pseudo-nodules. The M3 and M4 progenies were fertile and bred true.
