| Abstract: | Treatment of Pisum sativum (L.) cv. ‘Sparkle’ with ethylmethane sulfonic acid or γ or neutron radiation induced stable mutants which do not form nodules, or form few nodules. Six mutants were at the previously described sym 5 locus. Non-nodulating mutants of Melilotus alba annua (Desr.) cv. U389 were obtained by treatment with ethylmethane sulfonic acid (EMS) or neutron radiation, but not by γ radiation or azide. |
