Abstract :
The aim of this paper is to discuss the stability of grain yield varieties of rainfed wheat using the GGE (genotype main effect plus genotype by environment interaction). New varieties have to be determined by the plant breeders that are responsive for grain yield in the environmental change. In the current study, Nineteen wheat varieties in twelve different environments during 2009-10 with four replications in each environment using the RCBD (randomized completely block design) as the experimental layout. From the combined (ANOVA), the environment (E), Genotype (G) and genotype × environment interaction (GEI) effects were much significant (P<0.01). From the polygon view it is obvious that there were three winning genotypes which performed best in maximum environments for the rainfed wheat genotypes. G6 performed well in first megaenvironment that contained 6 environments, G4 in second megaenvironment and G7 performed best in the third mega-environments respectively among all environments. G10 was the most desirable genotype from the graph of genotype comparison and E9 was the desirable environment from the graph environments comparison.
