The inability of aminoazotoluene to induce somatic crossing-over or mutation in Glycine max (L.) merrill

Seeds from varieties T219 and L65–1237 of Glycine max heterozygous for the gene combination Y₁₁y₁₁ controlling chlorophyll development were soaked in aqueous solutions of aminoazotoluene (AAT) for varying time periods. Analysis of the simple leaves and the first compound leaf for spots indicated that this drug did not increase the frequency of mutation or somatic crossing-over in this system.
