Abstract

In order to evaluate some morphological traits of durum wheat genotypes, 18 elite lines selected from advanced regional durum wheat yield trials. These materials along, with two checks Dena (durum wheat) and Parsi (Bread wheat) were examined using RCB design with three replications at Isfahan research station in two consecutive cropping season. During the cropping season some trials such as the days to heading, days to maturity, plant height, and grain yield were measured and recorded. Analysis of variance showed that 1000 kernel weight, days to 50 percent heading and days to maturity in lines were significant. Effects of year and year × line were not significant for grain yield that indicated good yield stability for these lines. Cluster analysis indices the 20 genotypes separated into three groups, group III had the high grain yield. Number six line had the highest mean for the plant length and thousand kernel weight in comparison to the majority of the other lines. This line was separated from other lines in the dendrogram. Our factor analysis (FA) indicated that the first two factors account for more than 67% of the total variation. The most important traits that created this variation were seed weight and plant height.
