Common vetch ) Vicia sativa .L) is belong to Fabaceae family and due to adaptation and tolerance to environmental stresses are considered. In this research, morphological and agronomic characteristics of 89 genotypes of common vetch ) Vicia sativa .L) were evaluated in an augmented design under irrigated and drought stress conditions in research field of University of Tehran at Karaj in 2011. Relationships among different characteristics using multivariate statistical analysis methods were analyzed. The result of coefficient correlation analysis revealed significant positive correlation between yield and plant height, pod number, seed weight, dry forage yield, seed number per pod, plant height and internode number of flowers. Also there was a significant positive correlation between yield and plant height, pod number, seed weight, dry forage yield, seed number per pod under stress condition. Stepwise regression analysis in normal condition showed number of pods, number of seeds per pod, seed weight, internode distance and days from sowing to pod in normal condition and number of pods, number of seeds per pod, seed weight and internode distance in stress condition were the most effective in yield.
