In order to evaluate 164 durum wheat landraces from wheat collection of Seed and Plant Improvement Institute, Karaj, Iran, this study was undertaken along with four wheat genotypes Veery/Nacozari, Soisson, Dena and Zardak as checks. The plant materials were sown on an observation nursery. The checks were repeated systematically after every 30 lines. All genotypes were evaluated for different agronomic and morphologic traits during 2010-11. The results indicated positive relationship between grain yield and spike weight, number of grains per spike, grain weight per spike and 1000 grain weight. Classification of the genotypes was performed using factor analysis. It classified fourteen traits in five new variables (five components) which explained 77.02% of the total variation. Based on the results, 120 lines were selected. The results of this study relived presence of high genetic variability among the landraces for different traits, therefore these materials are valuable genetic resources that can be added to the wheat gene pool for breeding proposes.
