Abstract

To evaluate drought to lorance in promising dryland DURUM WHEAT genotypes, this study was carried out during two cropping seasons (2001-2003) in Maragheh Agricultural Research Station. Experimental materials included: seven promising DURUM WHEAT genotypes, one check (Zardak) and three bread wheat genotypes (one landrace, Azar-2 and Sardari). The experiment was conducted using RCBD with four replications under dryland and irrigated conditions. Quantitative criteria for stress resistance As: stress susceptibility index (SSI), tolerance index (TOL), mean productivity (MP), stress tolerance index (STI), and geometric mean productivity (GMP) were used for evaluation genotypes response to stresse. Results showed that in dryland condition effects of year and year genotype were highly significant (P≤0.01) on grain yield. In irrigated condition the main effects of year and genotypes were highly significant on grain yield. In comparison of the DURUM WHEAT genotypes with bread wheats the former had good tolerance under stresse condition and genotype no.4 (61-130/414-44//377-2/4/Df 21- 72//61-130/Uvy/3/128-13ya05509-1A-9A-2A-3A-OA-OAp) had the highest tolerance among the DURUM WHEATs.Among the criteria MP, GMP and STI had positively and highly significant correlation with grain yield under stress and non-stress conditions. Those criteriare recommended for screening of susceptible and resistant DURUM WHEAT genotypes for drought stren.
