Online published on 23 December, 2016. Abstract The present investigation was carried out at Department of Genetics and Plant Breeding, UAS, GKVK, Bengaluru during kharif 2014. The experiment was laid out in plant toprogeny row method in a single replication having 63 M3 mutant families treated with Ethyl Methane Sulphonate (EMS). The ‘t’ test revealed that significance difference between the mean of mutant families and parent (SB-42) for all the characters studied except hundred seed weight. Mean values of the M3 population were positively shifted for all the character except plant height and days to flowering. The higher magnitude of GCV and PCV was observed for number of branches plant−1 followed by moderate for observed for plant height, plant spread, number of pods per plant, pod yield per plant, seed yield per plant and plant dry weight indicating the genetic variability in the population and thus scope for improvement of these traits. In the present study, traits like number of branches plant−1, plant spread, number of pods plant−1, pod yield plant−1, seed yield plant−1 showedhigh heritability coupled with high genetic advance percent of mean indicating these traits are controlled by the additive gene action which is very useful in standard selection.
