Abstract
An experiment was conducted to assess genetic variability in mutagenic population through induced chemical mutagen on three chickpea genotypes of different concentrations of sodium azide (0.01, 0.02, 0.04, 0.06, 0. 08) along with control were evaluated on 11 quantitative characters in M1 generation of chickpea. Among 18 mutant lines highest seed yield was recorded in 0.08 concentration of BRC-1055-155 coupled with early days to 50% flowering, plant height, number of secondary branches per plant, number of pods per plant, maximum number of effective pods, biological yield and harvest index. The high estimates of GCV and PCV was recorded in number of effective pods per plant coupled with high heritability, high genetic advance and high genetic advance as percent mean. Grain yield indicated significant positive correlation with biological yield in both phenotypic and genotypic correlation co-efficient. Path co-efficient analysis showed positive significant direct effects on grin yield was exhibited by biological yield, seed index, harvest index, number of effective pods per plant, number of pods per plant and number of secondary branches per plant at both genotypic and phenotypic level. Treatment with sodium azide seems to be more effective in seed yield, biological yield and number of effective pods per plant in M1 generation. This conclude that sodium azide was found to be effective in inducing genetic variability and it can be considered for further selection, improvement and development of yield characters in chickpea.
