Abstract

In present study, FACTOR ANALYSIS and contribution of traits ingeneration of quantitative traits in BARLEY were studied. Fourteen genotypes of BARLEY were examined using a Split-Plot design based on Randomized Complete Block Design (RCBD) with three replications. Levels of water stress treatments were defined as main plot (perfect, ½ and no irrigation) and genotypes were considered as subplot. A positive significant correlation (P<0.99) was indicated between grain yield and DRY MATTER REMOBILIZATION of stem. FACTOR ANALYSIS determined five factors for perfect and of ½ irrigation and four factors for stopped irrigation that explained 83.9, 83.7 and 74.1% of the data’s changes. In general, contributions of DRY MATTER REMOBILIZATION from stem and peduncle to grain were highly important in all three stress levels. By increasing the stress level, DRY MATTER REMOBILIZATION from stem and peduncle to grain, seed weight, plant height, second intern ode length, peduncle length and spike length were more effective than traits like efficiency of remobilization from stem and peduncle to grain, number of seed per spike and grain yield in screening of genotypes. Overall, it can be concluded that traits related to remobilization can be considered as important indicators for evaluating and screening of BARLEY genotypes under drought stress conditions.
