Abstract:Drought stress is the most common adverse environmental condition that can seriously reduce crop productivity. Increasing crops resistance to drought stress would be the most economical approach to improve agricultural productivity and to reduce agricultural use of fresh water resources. As a result, understanding of the mechanisms of drought tolerance and breeding for drought-resistant crop plants has been the major goal of plant biologists and crop breeders. We evaluated ten oat cultivars under stressed and non-stressed conditions using a randomized complete block design in 2004 and 2005. The drought tolerance indices, GMP, MP and STI were determined as best indices, which can be used in breeding programs. The cultivar Paisley was found to be good for cultivation under stressed conditions, but other cultivars (Derby and Donald) had low yield and were not suitable for cultivation in Shahrekord region.
