The experiment was conducted during Rabi-2016-17 season at RKMVERI, Farm, Narendrapur, Kolkata, West Bengal. The mean values showed significant variation among the genotypes. UTKARSHA has recorded highest no. of seeds per pod (14.00), pod length (10.87 cm) &100 seed weight (5.74g) whereas lowest plant yield was recorded by KM-12-15(5.78g). The phenotypic coefficients of variation (PCV) for all the traits were higher than the corresponding genotypic coefficients of variation (GCV). High heritability along with high genetic advance (% of mean) was recorded for 100 seed weight, number of pods per plant & plant yield indicating that the heritability is due to additive gene effects for controlling the trails & used for further breeding programmes for improvement of these traits. Most of the yield attributing characters showed positive phenotypic & genotypic correlation with plant yield. As per Analysis of Euclidean distance it is clearly seen that the PUSA-0932 and SONALI (2.87) was closely related to each other. Some genotypes showed high percentage of protein. Protein content & total carbohydrate were positively correlated with the yield per plant and the coefficient was high. Based on three RAPD primers genetic diversity was analyzed for all eighteen genotypes. OPA 06 showed high polymorphism (80%) followed by OPA 08 (72.72%) and OPA 03 (50%). Among the eleven clusters, cluster II observed as large one comprising 4 genotypes namely KM-12-46, KM-15-74, KM-15-90 and SM-12-13.
