عنوان مقاله [English]
In order to evaluate the effect of growth habit on agronomic traits such as days to heading and physiological maturity, grain filling period, plant height, 1000 kernel weight and grain yield, an experiment was conducted as randomize complete block design with three replications with 259 barley genotypes at Maragheh dryland agricultural research station during 2004–2006. Based on the growth habit, genotypes were grouped as winter type (62.16%), facultative type (15.44%) and spring type (22.4%). Comparison of means for grain yield showed that there were high significant differences between winter with facultative and winter with spring types, but it was not significant between facultative and spring types. Spring-type genotypes had the highest grain yield mean with 2893 Kg ha-1. The existence of negative correlation between growth habit and grain yield and 1000 kernel weight showed that spring type genotypes had high yield and 1000 kernel weight. There were also negative correlation between growth habit and days to heading, maturity and plant height indicating that spring type genotypes had high height and late maturity. High positive correlation between grain yield and plant height showed that genotypes with high plant height had higher grain yield under drought condition.
