Abstract

Limitation of water resources and expansion of harvested area in order to increasing crop production appear the importance of accessing tolerant genotypes to severe conditions with high water use productivity. In order to evaluate grain and GRAIN YIELD components and some agronomical traits of spring WHEAT genotypes in DROUGHT STRESS condition, three seperate experiments were carried out, based on 100%, 75% and 50% crop water requirement in optimum I condition, moderate and severe stress, respectively on six spring WHEAT genotypes (including Fung, Chamran, Star, Stork, Showa and Green) in Ahwaz climatic conditions in 1999- 2000 . Randomized Compelete Block Designs (RCBD) with three replications were applied for comparing the genotypes. Based on combined analysis of variance, There were significant differences among genotypes in 5% level for a number of spikes / unit, a number of grains / spike let and biological yield, and in 1% level for thousand grain weight, grain harvest index and a number of spikelets/ spike and a number of seed / square meter. There was positive correlation COEFFICIENT at 1% level between GRAIN YIELD and biological yield, while the correlation COEFFICIENT between GRAIN YIELD and thousand grain weight and grain harvest index was non significant. Based on all data Fung and Chamran cultivars produced the higher GRAIN YIELD under optimum condition, while Stork and Chamran showed higher GRAIN YIELD under moderate stress condition. Stork and Green cultivar produced high GRAIN YIELD under severe stress.
