![]() Cluster analysis, based on the traits studied, divided the landraces into three groups. Correlation coefficients revealed that, number of seeds per plant and harvest index had significant and positive effect on seed yield under drought stress. Drought stress also reduced of plant height, number of pods per plant, number of seeds per plant, 100- seeds weight, hectoliter weight, biological yield, grain yield and harvest index of the lentil landraces under study. Mean comparisons also showed significant variations among the landraces for number of pods per plant, number of grains per plant, 100- grain weight, hecto liter weight, biological yield, grain yield and harvest index. Grain yield and number of grains per plant were highly influenced by drought stress. Analysis of variance indicated remarkable diversities among the landraces under study and significant differences for interaction of genotype by drought stress levels were obtained for most of the traits measured. The primary factor consisted of drought stress treatments at 2 levels (non stress and stress after flowering) and secondary factor of 15 lentil landraces. It was performed at the Agricultural Research Station of Islamic Azad University, Tabriz Branch, during the cropping year of 2011. In order to compare and classify of 15Iranian lentil landraces under drought stress conditions after flowering, an experiment was carried out in split plot lay out based on randomized complete block design with four replications.
