Abstract: An experiment was conducted with a set of seventy-one genotypes of Desi chickpea to estimate genetic variability parameters in Randomized Block Design with three replications under normal (5^th November) and late sown (3^th December) conditions during Rabi-2016-17. The analysis of variance for both the sowing conditions revealed highly significant differences among the mean square due to genotypes for all the characters. The range of variation was comparatively wider in late sown condition than in normal sown conditions. In both the sowing conditions, wide range of variation was observed for seed yield per plant and 100-seed weight, number of pods per plant, number of primary branches per plant, plant height and reproductive phase duration. Development of short duration genotypes could be helpful in attaining higher seed yield in late sown condition before onset of end season temperature stress. The differences between phenotypic and genotypic coefficient of variation (PCV and GCV) were not substantial. In both conditions, the high to moderate values of GCV and PCV were observed for 100-seed weight followed by seed yield per plant numbers of pods per plant, numbers of primary branches per plant, plant height and reproductive phase duration. High heritability coupled with high/moderate genetic advance expressed as percentage of mean were exhibited by 100-seed weight, seed yield per plant, number of pods per plant, plant height, reproductive phase duration, number of primary branches per plant and days to 50 per cent flowering. So, these traits can be used as selection indices to improve seed yield in late sown condition as well as timely sown condition.
