ABSTRACT
Twenty-three medium maturing genotypes of pigeonpea were evaluated at four environments during kharif 2019-20, to study genotype x environment interaction for yield and its contributing traits. The experiment was laid out in a Randomized block design with three replications. Analysis of variance in each environment and on a pooled basis expressed a significant difference among genotypes for yield and yield contributing characters, except for days to flowering and branches per plant. Environment (linear) interaction component was significant for all the traits. Non-significant genotype-environment interaction indicated a similar response of the genotypes to the varied environment. The variance due to pooled deviation (non-linear) was highly significant for all the characters, which reflect a considerable amount of genetic diversity in the material. The genotypes SKNP 1614, GJP 1820 and BP 16-273 were high yielding and stable across environments for seed yield.
