Ten promising groundnut varieties were evaluated under farmer’s participatory varietal selection method to know the genotype × environment interaction at five different locations. Analysis of variance revealed that the mean squares due to genotype were highly significant for all the characters studied. Variance due to environments was significant for all the characters studied except shelling percentage, sound mature kernels and hundred kernel weight. Significance of variance due to genotypes × environment interaction was recorded for days to maturity, plant height, shelling percentage, sound mature kernels and hundred kernel weight. A perusal of data for dry pod yield revealed that six out of the 10 genotypes, (Kadiri-9, Dharani, TG-51, TMV-2, G2-52 and GPBD-5) exhibited non-significant deviation from regression. Genotype Kadiri-9 recorded higher mean (1514 kg/ha) than population mean (1405 kg/ha) with regression coefficient of 0.85 for dry pod yield, indicating this genotype performs well under different environments. Genotype Kadiri-9 found stable for major traits like dry pod yield, haulm yield and sound mature kernels indicating the potentiality of this line to exploit the hybrid vigour for pod and haulm yield.
