Abstract

In order to evaluate and classify MORPHOLOGICAL AND MORPHO-PHYSIOLOGICAL TRAITS of BREAD WHEAT genotypes in drought and non-drought stress conditions 567 BREAD WHEAT genotypes were sown in modify augmented design with four replications. Two replications were considered as drought condition and two as non-drought. FACTOR ANALYSIS based on principal component analysis method and VARIMAX ROTATION indicated that four important factors accounted for about 89.6 and 87.5 percent of the total variation among traits in drought and non-drought stress conditions, respectively. In drought stress condition, the first factor assigned 42.8 percent of total variation between traits and was significantly related with spike yield and it’s components. Therefore, this factor was regarded as spike seed yield factor. Other factors in drought stress condition accounted for 20, 17 and 10 percent of variation between traits and were entitled as plant seed yield, spike density and assimilate transmission factors, respectively. In non-drought stress condition, the first factor assigned 35 percent of total variation between traits and was significantly related with traits plant and spike seed yield, plant and spike harvest index, No. seed/spike and plant height. This factor was regarded as plant seed yield factor. Other factors in non-drought stress condition accounted for 25.5, 16.6 and 11 percent of variation between traits and were entitled as production, assimilate transmission and spike density factors, respectively. Overall, results revealed effect of different environments on extracted factors, percent of variation accounted for by factors and traits related with each factor.
