- Abstract
In the present study, a total of twenty five blackgram genotypes were subjected to genetic diversity analysis based on nine different yield and yield contributing characters. The plant height (cm) contributed maximum 33.90 per cent towards total genetic divergence followed by seed yield per hectare (27.66%). All the 25 genotypes were grouped into nine clusters. The cluster I had highest number of genotypes (12) followed by clusters II, III, IV, V and VIII with two genotypes each. The intra cluster distance was highest in cluster VIII (6.94), followed by cluster I (6.92). Highest inter cluster distance was noticed between clusters IV and VI (54.35) followed by clusters VI and IX (38.06). From this study it can be concluded that sufficient amount of genetic variability was observed among the genotypes for yield contributing characters. Based on genetic diversity study hybridization programme can be effected between the genotypes of cluster IV (KU 96-3, LBG 752) and VI (KPU 128-105) in order to get transgressive segregants for yield and yield contributing characters, since these genotypes showed maximum diversity.
