Abstract

This study was conducted at Research Farm of Isfahan University of Technology to evaluate drought tolerance potential of 23 F2:4 WHEAT lines derived from the cross of Virmarin (susceptible line) and Sardari (tolerant line). A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3 and 120±3 mm evaporation from class A pan for non-stress and stress conditions, respectively). Drought tolerance and susceptibility indices were calculated for yield, and PRINCIPAL COMPONENTS analysis was performed on the basis of indices. Rosielle and Hambline tolerance index and Fisher and Maurer stress susceptibility index had positive and significant CORRELATION, but their CORRELATIONs with drought yield and the first two PRINCIPAL COMPONENTS were negative. High value of these components indicates low sensitivity to drought. The first component had high and positive CORRELATIONs with geometric mean productivity, stress tolerance index and harmonic mean. Lines number 4, 17, 11 and 14 with high yields in drought condition, showed high values for these indices. Line number 2 with high yield in nonstress condition and in spite of high sensitivity to stress, was a superior genotype based on these indices.
