Study of stability in promising lines of winter and facultative wheat (Tritium aestivum L.) emphasis with AMMI analysis

Fourteen genotypes were studied for grain yield and its stability in experimental stations of Ardebil،Eqlid، Arak، Zanjan، Tabriz،Mashhad،Jolgerokh،Miandoab،Hamedan and Karadj using randomized complete block design with three replications in tow years، Results of combined analysis of variance showed that the interaction effects of year×location and genotype×year×location were significant at 1% probability level، For determination of genotypes with high yield and stable، parametric and non-parametric statistics were used، Among the methods which were used. AMMI model was found more effective than the others. Based on AMMI (AMMI1،AMMI2andAMMI3) results،genotypes no; 2،5،6،7،8 and 9 were determined as stable in most of the locations، genotypes no; 9،10 and 13 for Karadj، no; 2 for Zanjan، no; 4 for Jolgerokh and Ardebil، and no; 7 for Mashhad showed specific adaptability.
