Abstract

Drought stress as the most important abiotic stress plays an important role in the yield reduction of crops in arid and semi-arid worldwide. Therefore, considering physiological traits correlated drought tolerance criteria is of major importance. As ICARDA origin, 19 genotypes were studied for selection of drought tolerant in the field and laboratory at agricultural college, Razi University, Kermanshah, Iran. The genotypes under investigation showed significant differences for yield under stress (Rainfed condition) and non-stress (Irrigated at three stages: shooting, flowering and maturity) environments, indicating the presence of genetic variation and possibility of selection for drought tolerance. Based on the physiological traits, leaf water content (LWC%) and chlorophyll fluorescence (CHF), the genotypes BW/5, BW/48, BW/104, BW/34 and BW173 were superior. STRESS TOLERANCE INDEX (STI) was high for the genotypes BW/5, BW/64 and BW/104. Screening under laboratory conditions, based on GERMINATION STRESS INDEX (GSI), the genotypes BW/5, BW/67, BW/48, BW173 and BW/104 with check variety were selected as tolerant. Evaluation of genotypes under investigation based on MULTIPLE SELECTION INDEX (MSI) revealed that genotypes BW/5, BW/64 and BW/104 had the most drought tolerance. Consequently, study of overall physiological and agronomic characters showed that genotypes BW/5, BW/64 and BW/104 have high drought tolerance.
