Ten groundnut genotypes were evaluated to know the role of G x E interaction and also to study stability performance over three environments. Analysis of variance revealed highly significant differences among the genotypes for all the characters studied. Genotypes x environment interactions were significant for all the characters under study indicating influence of environmental conditions.Stability analysis showed that both linear and non-linear components of G x E interactions were highly significant for all the characters. Environment (E 1 ) was observed to be most suitable for better expression of yield and its contributing characters. None of the genotype was found to be average stable for all the characters. Of all the genotypes, JL-24 and Phule Unnati for fresh pod yield/plant and TPG-41 and JL-24 for dry pod yield/plant exhibited average stabilityacross the environments.

The significant differences between 32 genotypes of wheat for all the characters were observed. Genotypes were grouped into six clusters with cluster I having maximum genotypes (18) followed by cluster III and clusters II, clusters IV and VI were monogenotypic. Maximum inter-cluster distance was recorded between cluster V and VI (860.24) and maximum intra-cluster distance was recorded in cluster III (130.18). Cluster III registered maximum cluster mean values for grain yield and important yield contributing characters like ear head length, spikelets per spike, tillers per running meter, grains per spike, 1000 grain weight, hectolitre weight and protein content. The highest contribution towards genetic diversity was contributed by plant height followed by protein content and 1000 grain weight. Therefore, for hybridization genotypes from cluster V and VI should be selected for obtaining desired recombinants in the segregating generations.
