چکیده

yield stability of 17 genotypes including eight of tritipyrum lines, five promising triticale lines and four iranian bread wheat varieties were studied in a randomized completely block design with three replications in seven environment during growing seasons of 2001-2002, 2002-2003, 2005-2006 and 2010-2011 in three locations. analysis of additive main effects and multiplicative interaction effects (ammi) showed that environment main effects and genotype × environment interaction were highly significant, so 89.49 percent of its sum of squares explained by the first three principal components (ipci). biplot results of genotypic and environmental components of interaction in the first, second and third principal components and mean yield of genotypes and environments, stability parameters of sipc3 and ev3 in ammi3 model and pattern analysis showed bread wheat cultivars had the unstable reaction to weak stability, triticale lines {4115, 4108} and kavir wheat cultivar showed the specific adaptation to the sixth environment (kerman) but, tritipyrum lines had the most stable reaction in different environments and combined primary line {(ka/b)(cr/b)-6} showed the specific adaptation to the neyriz area. combined primary tritipyrum line (ka/b)(cr/b)-5 with the higher yield than the mean yield and good general adapatibility was known the best genotype that can be used as a pasture line for further study forage and grain production
