Abstract
The presence of sufficient genetic variability, the knowledge of nature of association among different characters and relative contribution of different characters to yield is a prerequisite to any breeding programme. The aim of the present study was to estimate genetic parameters of 13 yield attributing traits in 36 Blackgram cultivars with a view to select better yield attributes in chickpea. P-1 (2.86g) was found to be superior for seed yield per plant among 36 genotypes followed by PLU-144 (2.80g), KU-96-4 (2.800g) and PUSA URD (2.6g). The higher value of phenotypic co-efficient of variation (PCV) compared to the corresponding genotypic coefficient of variation (GCV) for all the studied traits indicated that there was an influence of the environment. Among the 13 quantitative characters, high estimates of GCV and PCV were recorded for harvest index (32.66, 33.65), biological yield (27.28, 28.41), number of clusters per plant (23.99, 25.08) and number of primary branches per plant (22.19, 23.13). The present investigation high heritability coupled with high genetic advance was observed in harvest index (65.30, 94.20%), biological yield (53.98, 92.30%), number of clusters per plant (47.28, 91.50%), primary branches per plant (43.86, 92.00%), seed index (39.01, 90.00%), number of pods per plant (35.60, 84.30%) and seed yield per plant (34.18, 81.60%). Respectively suggesting that there was preponderance of additive gene action governing the inheritance of this character and offers the best possibility of improvement through simple selection. Hence selection of these characters can bring enhancement in chickpea production and productivity. Mahalanobis 
analysis revealed considerable amount of diversity in the material. The present investigation further revealed that genotypes belonging to cluster II have maximum intra cluster distance and can improve the yield potential. As maximum inter cluster distance was notice between cluster IV and V and cluster III and IV crosses involving genotypes from these clusters would give wider and desirable recombination’s. Therefore, genotypes present in these clusters are suggested to provide a broad spectrum of variability and may be used as parent for future hybridization programme to develop desirable genotypes.
