A set of 75 pigeonpea genotypes were evaluated during kharif 2017-18, to determine the genetic divergence among these genotypes for 17 seed yield and quality characters and to identify divergent parents. UPGMA method of Hierarchical Cluster analysis used with City Block distances grouped these genotypes into ten distinct clusters comprising of one to twenty genotypes. Maximum inter cluster distance was observed between cluster II and VIII followed by cluster II and VI and cluster II and IX. Genotype of cluster II showed highest mean values for plant height, methionine content and tryptophan content whereas, genotypes in cluster VIII showed highest mean values for number of pods, number of seeds and biological yield. Hybridization between the genotypes belonging to these distinct clusters is expected to produce desirable transgressive segregants. Genotypes AL 1404, AL 1356-04, ICPL 89011-1, AL 668 and AH 09-38 were found promising for both yield and quality traits and also belonged to distant clusters hence can be utilized for future pigeonpea improvement programmes.
