CORRELATIONS AMONG DIFFERENT STABILITY PARAMETERS FOR GRAIN YIELD IN CHICKPEA

Abstract

The presence of Genotype x Environment (G x E) interaction in plant breeding experiments led to the development of several stabiUty parameten in the put few decades. The interrelationships among different .tability parameten available,in the literature showed highly significant correlation between sf and bi, and among ~ ON, of, wf, 53.. i, 511, and 514. None of the parameten except CVI wu consistently correlated with mean yield. Ranking of genotypes based on these stabiUty parameten wu different over different subsets of environments within each trial indicating their poor repeatability.
