Abstract:
Experiment carried out for the studied of “Variability in M₃ generation of green gram” by inducing quantitative variability through mutagen to know the status of genetic variability parameters like GCV, PCV, Heritability and Genetic advance percent of mean. The genotypes differed significantly for all characters. The analysis of variance in M₃ generation for progeny within family indicated highly significant difference for plant height and chlorophyll content for majority of progenies. For all characters, phenotypic coefficient of variation was higher than genotypic coefficient of variation indicating that there was environmental influence on these traits. The combined results for heritability showed that the high estimates of heritability and genetic advance were scored for seeds per plant indicating that these characters were under the control of additive genetic effects. Environmental influence was high for all the observed characters. Individual plant analysis revealed significant variation among plants for all the characters, except number of pods per cluster.
