Abstract :

To study of efficacy of drought stress on the growth stages of durum wheat, a research split plot experiment based on randomized complete design with 3 replications was conducted at Islamic Azad University Tabriz branch, Agriculture Research Station in 2007. Main factor was stress in growth stages with 5 levels: a0 (without drought stress), a1 (stress in tillering), a2(stress in steming), a3(stress in flowering), a4 (stress in grain filling period) and minor factors were 8 durum wheat lines. Result of variance analysis showed that drought stress had significant effect on all traits. Also significant interaction of genotypes × stage of drought stress for all traits except biomass showed different behavior of lines for stresses in different growth stages. The drought stress in each growth stage of durum wheat, reduced yield and most effects of them were in tillering and flowering stages. The estimation of correlation between traits showed that there was significant and positive correlation between seed yield with harvest index. In this research, from calculated of resistance indexes, the STI and GMP were determined most suitable indexes, and according to this resistance index, the line of numbers 1 and 2 were of highly yield and most tolerant toward drought stress.
