Eberhart and Russell approach genotype by environment interaction (GEI) for yield and yield component traits in Vigna radiata L. Wilczek genotypes

Present study was carried out to identify stable mungbean genotype across various environments as the performance of each genotype tends to vary when grown in different seasons. Forty homozygous genotypes were tester over three season viz., kharif 2019, spring summer 2020 and summer 2020. Eberhart and Russell model of stability analysis was carried out which revealed significant effect of each environment on the genotypes, for all the ten agro-morphological traits except for number of branches per plant. Genotypes KM2355, LG544, and RMG1087 was found promising with stable performance across the three season; while the genotype KM2328 was identified as stable genotype under less favourable conditions. Finally, the genotypes, IPM147-1, NM159 and KM2312 were recognized as stable genotype under favourable conditions.
