يادداشتهاي مربوط به خلاصه يا چکيده : ‭.AbstractIn this study, water stress tolerance in wheat genotypes using GGE biplot and other forms of multivariate statistics were examined. The research in the agricultural research station, located in the city of Khorramabad, Lorestan University was conducted at 2014 crop season. Two separate experiments with 36 different genotypes in a randomized complete block design with three replications for each of the two irrigation treatments in stress and without stress was done. Analysis of variance of the data obtained from the experiments showed significant different among wheat lines for all the traits in without stress condition except for spike weight and height without spike and for all the traits in stress condition except for spike weight and kernel per spike at 1 and 5 probability percent, respectively. The results of comparison of the mean showed that Roshan genotypes with the highest yield had the best performance is stress and without stress conditions. According to drought index selection based on GMP, MP and STI similar results and in all other cases, Roshan, Hamoon and Parsi genotypes were identified astolerant genotypes and on this basis and given the high and significant correlation of drought tolerance indices with grain yield in stress and without stress conditions, indices MP, STI and GMP were selected as the best indicator. The principal component analysis in both conditions was done, and the first of five components with eigenvalues greater than one was 78.44 of the total variation in stress condition and the first of five components with eigenvalues greater than one was 84.40 of the total variation in without stress condition. Displayed biplot in without stress conditions confirmed 48.5 percentage and biplot in stress conditions 53.1 percentages justified of the total variation. Polygon schema GGE biplot is applicable for identification of the genotypes with the highest values for one or more attribute. Based on the polygon schema in both stress and without stress conditions, Roshan genotype showed the highest value‬
