Abstract

To evaluate the relationship among different agronomic characteristics and GRAIN YIELD in HULL-LESS BARLEY genotypes under rainfed conditions of Koohdasht, Lorestan, Iran, this experiment was conducted in 2003 to 2005 cropping seasons. Twenty spring HULL-LESS BARLEY genotypes were evaluated in Randomized Complete Block Design with four replications. Relationship between agronomic characteristics and GRAIN YIELD were investigated.Results showed that spike weight had the highest correlation coefficient with the number of grain.spike-1 (r=0.96**). Correlation coefficient between GRAIN YIELD and BIOLOGICAL YIELD was (r=0.81**). To determine the most effective characters on GRAIN YIELD, stepwise regression analysis was performed. Five traits including; spike weight, number of grain.spike-1, peduncle length, plant height and number of days to heading, were the most effective traits on GRAIN YIELD. The path analysis showed that spike weight (r=0.89**) and plant height (r=0.82**) had highest positive and direct effects on GRAIN YIELD in HULL-LESS BARLEY genotypes.
