The present investigation was carried out for estimation of genetic variability in 242 BC3F4 chickpea (Cicer arietinum L.) lines derived from the cross Annigeri-1 × WR-315 through marker assisted backcrossing (MABC) studied under rainfed condition. The yield and yield attributing traits were studied in BC3F4 MABC lines to understand the existence of genetic variability parameters. The MABC lines exhibited significant amounts of variability for all the characters studied. The wide range of variation provides scope to select superior and suitable genotypes. It was found that low GCV and PCV with narrow differences were recorded for days to 50 per cent flowering (3.79 and 4.78%) and days to maturity (1.33 and 1.86%) indicating that there was less influence of environmental factors. In general high heritability accompanied by high genetic advance as expressed in percentage of mean (GAM) was recorded for seed yield per plant, number of pods per plant followed by 100 seed weight respectively. This research paper reports that high heritability is due to the additive gene effects and promoted use high estimates of heritability coupled with high genetic advance for genetic improvement of these traits through selection in BC3F4 MABC lines of chickpea for future breeding programme.
