Characterization of Iranian bread wheat landraces for morpho-physiological traits associated with drought tolerance
Abstract
To evaluate the morpho-physiological traits related with drought tolerance in wheat landraces of Iran, 53 selected lines along with 10 cultivars were grown in randomized complete blocks in 2012. Agronomic characters, physiological traits such as relative water content (RWC), cell membrane stability (CMS), chlorophyll fluorescent (Fv/Fm), activity of ascorbate peroxidase (APX), catalase (CAT) and superoxide dismutase (SOD) enzymes were measured. Significant differences were observed among the genotypes in all of the traits. Among the genotypes, 7 lines had higher grain yield than the best yielding variety. Sixty percent of lines had higher seeds/spike than the best control cultivar. Eighteen lines had higher RWC than the best control variety. Thirteen lines had higher APX activity and Fv/Fm than the best control variety. Four lines had higher CAT and SOD activity and CMS than the best control variety. Yield had positive correlation with HI and all of physiological traits except for CMS. In regression analysis, RWC, HI, Fv/Fm along with CAT and SOD activities were entered in the model and 65% of variation of yield was explained.
