Assessment of Quality Traits of some Advanced Lines of Durum Wheat at Isfahan

In order to assessment of quality traits of durum wheat lines, 18 elite lines selected from advanced regional durum wheat yield trial, ARDYT (2009-10) along with two check {including Dena(durum wheat) and Parsi (Bread wheat)} were studied in an experiment using RCBD with three replications at Isfahan research station in two consecutive crop season. Results showed a significant difference between the two years for all traits (except %protein). In first year lines 15 and 8 had the highest (%12.6) and lowest (%11.3) of protein percentage, respectively. While the highest (%13) and lowest (%11.7) of this character for second year were in control-1 and line 14, respectively. Cluster analysis classified lines in four main groups, that IV group had the highest protein percentage. The most of traits had a significant correlated. Factor analysis revealed that three factors confirmed more than 84% of total variance between the lines. The first factor confirmed 49% of the variation. In conclusion, the results of present study are suitable for crop and breeding programs.
