Twenty one pigeonpea genotypes were evaluated at four environments during kharif 2018-19, to study genotype × environment interaction for yield and its contributing traits. The experiment was laid out in randomized block design with three replication. 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 branches per plant and seeds per pod. Environment (linear) interaction component was significant for all the traits. Highly significant genotype-environment interaction indicated differential response of the genotypes to the environmental changes. The variance due to pooled deviation (non- linear) was highly significant for all the characters except for pods per plant and seeds per pod which reflect considerable amount of genetic diversity in the material. The genotypes GJP 1606 and GJP 1601 were high yielding and stable across environments for seed yield per plant.
