Genetic analysis of yield and yield attributing characters of blackgram (Vigna mungo (L.) Hepper) during summer season in gangetic alluvial soil of West Bengal

The experiment was laid out with twenty genotypes and three replications at Instructional Farm of Ramakrishna Mission Vivekananda Educational and Research Institute, Narendrapur, Kolkata, West Bengal. Among the genotypes RSU-03 showed significantly superior for number of branches per plant (9.07), number of pods per plant (26.27), 100 seed weight (5.15 g) and yield per plant (11.53 g). The phenotypic coefficients of variation (PCV) for all the traits were higher than the corresponding genotypic coefficient of variation (GCV). High heritability coupled with high genetic advance (% of mean) was recorded for no. of pods per plant, plant height, yield per plant which indicates the predominance of additive gene effects on the expression of these traits and these can be used for further breeding programmes for improvement of these traits. Some genotypes showed high percentage of protein and carbohydrate. Based on three ISSR primers, genetic diversity was analyzed. UBC-827 showed high polymorphism (88%) followed by UBC-856 (64%) and ISSR-33 (58%). Among the seven clusters, cluster VI stands out to be the largest.
