Abstract

In order to evaluation of effective trait on grain weight cultivars of WHEAT under DROUGHT STRESS, an experiment, complete randomized block design factorial with 4 replication in two site: Karaj and Torbat - e- jam with 9 different regime irrigation on 3 WHEAT varieties was conducted. Results showed that grain yield, grain effective filing period, maximum weight of grain and thousand grain weight in Karaj site were greater than Torbat-e-jam site. The effect of DROUGHT STRESS treatment was highly significant (p£0.01). As T1, treatment had the greatest yield, GRAIN FILLING DURATION and the least GRAIN GROWTH RATE, and T8 had the least yield and GRAIN FILLING DURATION and the greatest GRAIN GROWTH RATE. DROUGHT STRESS conditions decreased grain-filling duration and increased GRAIN GROWTH RATE. Results of correlation showed that seed yield is positively and significantly correlated with GRAIN FILLING DURATION and, maximum weight of grain and negatively and significantly correlated with GRAIN GROWTH RATE. Results of stepwise correlation showed that grain-filling duration is the most important trait in justification of final weight grain changes and after that, GRAIN GROWTH RATE is another trait, which determines of final weight grain changes.
