Genetic analysis on genotype x environment interaction for seed yield in greengram (Vigna radiata (L.) Wilczek)

Nineteen cultures of greengram including two check varieties viz. CO 8 and VBN (Gg) 3 were evaluated for four seasons at NPRC, Vamban. The data on seed yield were subjected to genotype x environment interaction analysis to identify high yielding stable greengram culture. Significant G x E interaction depicted differential performance of the cultures over environments. Based on stability analysis, it was concluded that the genotype VGG 15–030 was found to be a high yielder, stable performer with no response to environments. It can be recommended for both kharif and rabi seasons. The genotype, VGG 15–035 was found to be high yielder, stable performer with above average response to environments. Hence this culture can be recommended to favourable environments.
