Genetic Diversity of Grain Yield and some Morphological Traits in Local Bread Wheat Lines

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
