Evaluation of drought tolerant cultivars and lines of sesame using stress tolerance indices
Journal Title: Scientific Journal of Crop Science - Year 2014, Vol 3, Issue 6
Abstract
Inorder to evaluation drought tolerant of cultivars and lines of sesame,using indicators of "stress tolerance" two separateexperiments, was carried out using randomized complete block designin three replications during crop year 2010-2011 at theagricultural research station of Zahak. In the no stress condition, irrigation was performed basedon plant growth stages. And in condition of season's end stress,water interruption from flowering stage until end maturity (post–anthesisdrought stress). The results showed that in the studied indices,three indices of MP, GMP and STI, with grain yieldin stress and no stress conditions had the highest positiveand significant correlations. Comparison of the values obtained fromindices for each genotype showed that,"Darab-14" and "Sistan local" withhaving higher sustainability and performance in stress and non-stress conditions hadthe highest values of indices of STI, GMP and MP, andwere determined as most tolerance genotypes with high yield, thusthey can be used in breeding programs.
