Dry seeds of variety PS16 of P. aureus [Vigna radiata] were exposed to 20 kR gamma rays while presoaked seeds (moisture content 12.6%) were treated with 0.3% ethyl methanesulphonate and 0.04% hydrazine hydrate for 6 h. Seeds per pod, 100-seed weight and total plant yield were evaluated in the M1, M2 and M3. Changes in variability were dependent on character, treatment and generation. Analysis of the data revealed that the values for the genotypic coefficient of variation, heritability and genetic advance of the characters were higher in the M3 than in the M2, indicating that gains could be achieved by selection in the M3.
