The genotypes were also assessed for change in the nature of inter-relationships and path effects of different characters towards pod yield. Mean performance of genotypes indicated that Nippani was the most favourable environment for better expression of most of the characters. Analysis of variance revealed significant differences among most of the characters suggesting a high degree of variability among the genotypes tested. Genetic variability analysis revealed pod yield per plant and hundred kernel weight had higher variability, heritability and expected GAM as compared to other traits. The pooled analysis of variance revealed significant differences among the genotypes and environments for most of the characters indicating the genotypes and environments tested are diverse in nature. Genotype x environment interaction was significant for all the traits suggesting genotypes interacted significantly with the environments. While, genotype x environment (linear) interaction was significant for plant height, pod yield per plant and shellirg per cent indicating genotypes responded linearly to the changing environment. The non-linear component (pooled deviation) was highly significant for all the traits indicating this part of the variation in terms of performance of the genotypes is unpredictable. On the basis of stability parameters, Dh-104 and Mutant III were promising genotypes for majority of characters with higher mean performance across the six environments. The association analysis revealed that pod yield per plant exhibited significant positive association with number of pods, shelling per cent and SMK per cent at five locations and path analysis indicated that number of pods, shelling per cent and SMK per cent exerted high direct effect each in three locations.ennullThesis
