Abstract

Seeds of cultivars Bragg and Type 49 were treated with various doses of γ rays and/or various concentrations of ethyl methanesulfonate (EMS). In the M3, the 15 krad γ ray treatment or treatment with 0.2, 0.4 or 0.6% EMS increased seed yield/plant significantly, while the 0.2% EMS treatment increased yield/plot significantly over untreated controls. Total variances within treated populations were significantly higher than the variances within control populations for most of the characters studied, indicating induced polygenic variability. The greatest difference between variances (a factor of about 14) was for seeds/pod between Bragg and its M3 from the 0.6% EMS treatment; the trait in this treatment also had the highest heritability estimate (up to 94%).
