Abstract:

The investigation consisting of thirty five blackgram genotypes along with four check varieties viz., MBG-207, LBG-752, PU-31 and IPU-2-43 was carried out during rabi 2016 at Agricultural Research Station, Madhira. Three principal components viz PC I, PC II and PC III contributed about 86.61% of total variance for the genotypes studied. The genotypes were grouped into nine distinct clusters of which cluster 1 is the largest with a maximum number (22) of genotypes followed by cluster 5 with 7 genotypes, cluster 3 with 4 genotypes. Highest intra cluster distance of 32.38 was recorded for cluster 5. Data on cluster means for various traits showed that the highest mean value for number of clusters per plant and number of pods per plant was recorded by cluster VII. Cluster VIII recorded the highest mean for 100 seed weight followed by cluster III and cluster IV. Percent contribution revealed that days to maturity contributed the most (26.58%) followed by number of cluster per plant (18.08%), seed yield per plant (17.40%), 100 seed weight (14.84%) for total genetic divergence.
