بررسی ژنوتیپ‌های مختلف گندم دوروم در رابطه با تحمل به تنش خشکی با استفاده از روش‌های آماری چند متغیره

To investigate the genotype of durum wheat in drought tolerance ,a pilot in the summer of 1392 in a greenhouse at the Faculty of Agriculture, University of Mohaghegh Ardabil using 20 genotypes of durum wheat at two levels of drought stress(0.4 and 0.7 stress, when the 40 % and 70 % of available to plants Is fully discharged) and a control surface (complete irrigation),the experimental split plot in a completely randomized design with three replications .The results obtained from the analysis multivariate different tests (Pilli′s trace, Wilk′s lambda, Hotelling′s Trace and Roy′s largest Root) showed that in all the test statistic is significant at the 1% level and significant differences between the control and stress levels exist. The results of the factor analysis indicate that the level of control 44.119 % of the variation by the first factor and 27.306 % of the variation was explained by the second factor. The surface stress0.4 to34.098% of the variation by the first factor and 30.130 % of the variation was explained by the second factor. The surface stress 0.7 to 36.600% of the variation by the first factor and 36.157% of the variation was explained by the second factor.
