In order to estimate the effect of water stress on yield and yield components of spring Brassica Oilseed, an experiment was conducted at the center of Agricultural and Natural Resources Research of Khorassan Razavi- Iran, on 2009-2010. The experimental design was RCBD with three replications and 9 cultivars of spring canola in two conditions (water stress and without water stress). There was significant difference among cultivars for yield and yield components. Drought stress caused to significant redaction of seed yield, branches per plant, plant height, dry weight of plant and harvest index at 1% level, and pods per plant at 5% level. But there were no significant difference between two conditions for 1000 seeds weight and seed/pod. Cultivars of B. napus showed higher seed yield than B.rapa and B.Juncea species at both conditions.
