Notes:
Summary Mutagenesis ofVicia faba L. using ethyl methanesulfonate has yielded three mutants (f13, f73, f245) with ineffective nodulation (Nod+Fix−), one mutant (f48) unable to nodulate (Nod−) and one supernodulating mutant (f32) having 3 to 5 times more nodules than the control in the absence of combined nitrogen, and expressing nitrate tolerant nodulation (Nod++, Nts). All of the mutant phenotypes were controlled by single and distinct recessive genes designatedsyml tosym5, respectively. Grafting experiments showed that the (Nod+Fix−) and (Nod−) phenotypes were both under root genotype control and that the (Nod++, Nts) phenotype was under shoot genotype control.
