Evaluation of drought tolerance of bread wheat genotypes by use of stress tolerance indices
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 1
Abstract
In order to identify traits effective on the yield and determine the best and most efficient drought tolerance indices for bread wheat in cold region of Ardabil, an experiment was conducted on 8 bread-wheat genotypes (treatment) based on complete randomized block design with three replications at experimental farm of Islamic Azad University, Ardabil Branch, in 2010. Examination of drought tolerance indices revealed that indices such as STI, GMP and MP were highly correlated with Yp and Ys, which were designated as the most efficient indices. Moreover, genotypes such as Tous and 4041 by producing the highest yield were the most tolerant genotypes. Saratovskaya-29 was identified as the weakest genotype in the region both at stressed and normal conditions.
