Abstract

Divergence analysis among fifty groundnut genotypes was carried out using Mahalanobis’s D2 statistic. The genotypes were grouped into twenty-seven clusters. The maximum inter-cluster distance was found between clusters XXVII and XVIII (D=22.53) followed by clusters XXVI and XVIII (D=20.79) and XXVII and XXIII (D=20.63) indicated that these groups of genotypes were highly divergent from each other. The genotypes in above clusters revealed substantial difference in the means for important yield contributing characters suggesting that the genotypes belonging to these clusters from ideal parents for improvement in groundnut.
