Abstract:

Cluster and association analysis were studied for yield maximization and yield attributing traits in pigeonpea [Cajanus cajan (L.) Millsp]. There was significant variation observed for all the characters under study. Association studies revealed that seed yield per plant was positively associated with number of pods per plant, number of pod clusters per plant, number of primary branches per plant and pod length. Cluster analysis result showed existence of considerable diversity in pigeonpea germplasm accessions. The maximum inter cluster distance was observed in between cluster I and VI. Hence, genotypes belonging to cluster IV may be utilized as parent in future breeding programmes with the genotypes belonging to cluster I to obtain better/heterotic segregants.
