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