G X E Interaction and stability analysis in chickpea (Cicer arietinum L.)
Abstract:
G X E interaction and stability analysis were carried out in four environments comprised of two different dates of sowing with two different locations for 10 diverse genotypes. Analysis of variance for genotype x environment interaction and stability analysis suggested that the variance for G x E interaction was significant for number of pods per plant, seed yield per plant, 100-seed weight, harvest index and protein content. The genotypes IC-269273, IC-269295 and three cultivars i.e., GG-1, GJG-3 and Dahod Yellow were stable across environments. Out of these five genotypes, Dahod Yellow having the highest average seed yield per plant was found most stable over environments. Thus, any of the germplasm entry under study was not found superior with respect to seed yield per plant against the three cultivated varieties.
