GENOTYPE ENVIRONMENT INTERACTION FOR YIELD COMPONENTS IN PIGEONPEA (Cajanus cajan (L.) MILLSP)

Abstract

                                None of the six pigeonpea cultivars over three different seasons could be identified for yield stability. However SA 1 and PLS 361/1 were identified for the stability of number of branches, number of pods per plant, number of seeds per pod and 1000-grain weight. The genotype-environment interaction is highly significant for all the yield components except number of seeds per pod. This study also suggests that these two cultivars can be used for crop improvement studies in pigeonpea.

Key words : G x E Interaction, Pigeonpea, Yield Components
