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.
