گروهبندی لاینهای اینبرد نوترکیب گندم نان در شرایط آبیاری مختلف بر اساس صفات مورفولوژیکی و زراعی

To evaluate response of bread wheat recombinant inbred lines to water deficit stress and their grouping, an experiment was conducted using split plot design based on completely randomized blocks design with three replications during 1391. The main and sub-factor consisted of two irrigation levels 38 recombination inbred lines along with their parents (Zagros and Norestar) respectively. Analysis of variance revealed significant difference between irrigated levels for all the studied traits except spike length. Differences among Lines and cultivars were significant for all the traits. But line × irrigation interaction was not significant for non of the traits. Cluster analysis using Ward algorithm and based on standardized data all the traits assigned the lines into three groups and analysis canonical confirmed the grouping. Based on group mean division from overall mean, group 1, consisted of lines number 26, 265, 45 and 300 was identified as superior cluster.
