Abstract

An experiment was conducted focussing on creation of variability in soybean crop. Three soybean genotypes were evaluated for variability induced by gamma rays and EMS mutagens for yield and yield attributing traits. Population generated from treatments with four doses of gamma rays and three concentrations of EMS along with control laid into randomized complete block design with three replications for evaluation. The experimental findings revealed that EMS had more pronounced effect in inducing the variability as compared to gamma rays. The higher estimates of GCV, PCV, heritability and GA as per cent mean was recorded by 0.2 per cent EMS treatment for most of the characters like plant height, number of pods per plant, 100 seed weight and seed yield per plant particularly in Soybean genotype TAMS 38 and RSC 10-46, whereas days to 50 % flowering, number of branches per plant, days to maturity, number of seeds per pod, oil content and protein content showed low to moderate magnitude of variability parameters in all soybean genotypes.

Keywords

EMS, Gamma rays, GCV, PCV, Soybean, Variability

Conclusion

Ethyl methane sulphonate mutagen found effective in inducing variability and in characters showing high estimates of variability simple selection may be rewarding.
