Stability Analysis of Fodder Cowpea Genotypes under Different Environments

Abstract

Stability of green fodder yield and its component characters was assessed for thirty genotypes over six environments (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 (RL-5, PL-4, EC 97738, FD-2262and FD-2258) were found stable for favourable environment and four genotypes (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.
