Author(s):

Abstract:
Estimation of G × E interaction was carried out in thirty cowpea genotype of diverse origin. The study was conducted at Pusa farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar by adopting randomized block design with three replications and spacing 45×10 cm. During kharif season 2019 and 2020 across six environment for days to 50% flowering trait being an important trait for fodder cowpea. All the studied genotypes showed significant interaction with environment and all thirty cowpea genotypes responded differently to evaluated environments. The analysis of GGE biplot revealed G29 (FD-2258) genotype was an ideal genotype and E1 environment as ideal environment for days to 50% flowering trait. The cowpea genotype G23 (FD-2229) was equally winner in both E3 and E6 environment; and genotype G29 (FD-2258) was winner in E1, E2, E4 and E5 for selecting superior stable fodder cowpea genotype adapted for the region.
