Assessing pigeonpea genotypes across various environments is an important activity for pigeonpea variety development programs. Generally stable and high-yielding genotypes that were identified are released for farmers’ cultivation. For this purpose, 10 genotypes of pigeonpea were examined for grain yield and yield components over the course of two consecutive years, 2020 and 2021, at three different locations-Khajura, Surkhet and Belachapi. A randomized complete block design (RCBD) was used in this study with three replications and plot size was 12 meters square per plot. Genotype and environment (G × E) interactions and stability analyses were performed for yield and yield components in a specific location. The results showed that genotype (G), environment (E) and their interaction (G × E) at a 0.05% probability level, significantly influenced the gra in yields of Pigeonpea genotypes. Genotypes ICP 7035 (bi = 1.05) and NPO2-1-1 (bi = 1.12) and Bageshwoti (bi = 1.14) with more than unity regression indicated the genotype’s suitability for favorable conditions. As shown by the GGE biplot, genotype ICP 7035 was stable in the tested environment.
