Genetic and physiological study of pea mutants

Sidorova, K. K.

Among 6 new mutants of the variety Torsdag obtained by treating the seeds with ethyleneimine, gamma rays or ethyl methanesulfonate, 4 had a compact stem (shortened and thickened to different extents), one lacked a waxy bloom on the leaves, and one had narrow leaflets. Hybrid analysis indicated that all involved monogenic recessive mutations with a pleiotropic effect. The mutants, together with forms heterozygous for the mutant genes, differed in response to gibberellin treatment.
