Abstract :Stability of green fodder yield and its component characters was assessed for thirty genotypes over six environments insert ignore into journalissuearticles values(two seasons 2019 and 2020 × three environments); to determine the quantitative response of cowpea genotypes. The investigation was undertaken at Pusa Farm of Dr. Rajendra Prasad Agricultural University, Pusa, Samastipur, Bihar under open field and rain-out shelter conditions in randomized block design with three replications. The results green fodder revealed that five genotypes insert ignore into journalissuearticles values(RL-5, PL-4, EC 97738, FD-2262and FD-2258); were found stable for favourable environment and four genotypes insert ignore into journalissuearticles values(RL-6, EC 390252, FD-2230, FD-2272); were found suitable for poor environment. The genotype, Kashigauri and Bundel Lobia-1 for green fodder yield were found suitable for average environment and encompasses fair stability and wider adaptation. Therefore, the genotype Kashigauri and Bundel Lobia-1 may be recommended for green fodder production after testing over time and space.
