Abstract

 In order to identify DROUGHT tolerance lines and screening indices of DROUGHT resistance, 10 advanced lines of DURUM WHEAT with control cultivar Dehdasht were studied in a randomized complete blocks design under two DROUGHT mild and sever stress conditions in Gachsaran region. Based on the yield trait on mild stress (YP) and severe stress (YS) conditions, quantities indices of DROUGHT resistance including: Mean productivity (MP), Tolerance index (TOL), Geometric mean productivity (GMP), Stress Susceptibility index (SSI) and Stress tolerance index (STI) were calculated. Genotypes no 1 and 6 with relatively high first principal component amount and low component amount in both enviroment, were selected as the best genotyps. Correlation yeild between two environment and DROUGHT TOLERANCE INDICES revealed that STI and GMP indices are the best indices for screening of DURUM WHEAT genotypes. Biplot multivariate graph showed that genotypes 1 and 6 are located in the vicinity of the vectors associated with DROUGHT resistance indices such as MP, GMP, STI and therfore were selected as the most resistant genotypes. In this research the plant canopy temperature difference with environment (CTD) in three growth stages was measuered that genotypes no 9, 10 and 6 had the coldest growing environment. Positive and significant correlation between SSI and CTD showed that canopy temperature index can have an important role in identification of DROUGHT tolerance genotypes.
