ABSTRACT

Ten genotypes of groundnut were evaluated during kharif and rabi seasons of 1997 and 1998. The analysis of variance indicated significant differences among four environments. Genotype x Environment interaction was significant for number of mature pods and pod yield. The environment (linear) and G x E (linear) component were significant for number of mature pods and pod yield. But G x E (linear) was not significant for these two traits when tested against pooled deviation indicating the preponderance of nonlinearity. The genotype VGN 24 recorded high mean value, average responsiveness and stability based on Eberhart and Russell's and genotype grouping method for the both traits.
