Abstract

Black gram (Vigna mungo L. Hepper) is a self-pollinated crop belonging to the leguminous family having high protein content. The present investigation was conducted during kharif 2021 at Pulses Research Sub-Station, Samba and Advanced Centre for Rainfed Agriculture (ACRA), Dhiansar of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu as Environment-I (E1), Environment-II (E2) and Environment-III (E3), respectively. The present experiments were executed to investigate the extent of genetic diversity and to identify promising genotypes for further utilization in the breeding program of black gram. The experimental materials were composed of thirty black gram genotypes which were planted in Randomized Complete Block Design (RCBD). The agro-morphological data were recorded of eleven traits from each environmental condition for plant height, number of days to 50% flowering, number of branches per plant, number of days to maturity, number of pods per plant, number of seeds per pod, pod length, number of clusters per plant, number of pods per cluster, 1000 seed weight and seed yield per plant. Stability analysis was done and followed the Eberhart and Russell model,1966. Genotype PU40 was the most stable genotype across the environments for 1000 seed weight, days to maturity and seed yield/plant. However, genotype PU35 was most stable for days to 50% flowering, days to maturity and number of pods/plant. These genotypes could be utilized in future breeding programme for seed yield/plant improvement in urdbean and pyramiding of components traits such as number of pods/ plant, 1000 seed weight, days to 50% flowering, days to maturity and seed yield/plant.
