Abstract

To assess the genetic variability of grain yield, yield components and some morphological traits in 99 BREAD WHEAT lines deriven from local genotypes, an experiment was carried out based on randomized complete block design with three replications during the 2010-11 and 2011-12 cropping seasons at Saatlou Station of Agricultural and Natural Resources Research Center of Urmia and at Research Field of Urmia University. Analysis of variance for biological yield and grain yield showed significant differences among lines in both years. The highest biological and grain yield belonged to line No.18 and line No.87, respectively. Combined analysis of variance indicated significant differences among interactions between lines and years for all studied traits except awn length, number of spikelets/spike and number of grains/spike (P<0.01). CLUSTER ANALYSIS based on mean traits using Ward’s method assigned the lines into seven groups. Similarity between results of multivariate analysis of variance and CLUSTER ANALYSIS was observed for classification of lines. Discriminant function analysis revealed that 88.9% of the grouping was correct. Groups 1 and 6 had the maximum mean of grain yield and yield components. In addition, the first three canonical functions explained 80.3% of the total variance. Canonical discrimination coefficients for these three functions indicated that grain yield, biological yield, spike length, plant height, thousand grain weights, flag leaf weight, flag leaf width, spike density and days to flowering were the most important for discriminating among wheat lines.
