Cluster Analysis and Correlation in Blackgram Germplasm

Abdul Ghafoor , Zahoor Ahmad and Afsari Sharif

Abstract:
Blackgram germplasm comprising of 484 genotypes was catagorized in 5 clusters based on average linkage. Ten per cent members from each cluster plotted for first 2 PCs revealed that clusters I, II, III and IV were grouped together, whereas cluster V was scattered in upper half of the graph. Two members of cluster V could be grouped together but third member was away which is a late maturing with lanceolate leaf shape. Correlation in total germplasm and selected accessions were similar in most cases. High correlation of grain yield with branches, pods/plant, pods/branch, seeds/pod, seed weight and biological yield for both the populations indicated the importance of these characters in determining yield potential for blackgram. In selected population, grain yield showed significantly positive correlation with days to flowering and maturity also, indicating the importance of selection pressure for these traits.
