description To investigate association of some morphophysiological characteristics with seed yield and its components of oilseed rape varieties, a research was carried out at East Azerbaijan Agriculture and Natural Resources Research Center in 2005-2006. Experimental design was randomized complete block with four replications. Varieties under study showed significant differences in leaf area and leaf number per plant (typeI, II and total), leaf dry weight per plant, specific leaf weight, leaf temperature, seed oil percent, seed and oil yields. The results indicated that high yielding varieties possessed higher levels of leaf area (type II). SLMO46, Sunday, ARC-2, Opera and Ebonite had the higher seed yields than other varieties respectively. Sunday, Ebonit, SLM046, ARC-2 and Opera produced higher and Okapi, Sinatra, Regent×Cob, Geronima and Olpro lower oil yields. In this research, a positive and significant correlations were observed between seed yield with oil yield, leaf area type II, total leaf area, leaf dry weight, while a negative and significant correlation between seed oil and seed yield were seen. Correlations of oil yield with seed oil, seed yield, leaf dry weight and leaf area (typeI, II and total) were positive and significant. It seems that leaf area, especially larger leaves with longer petiole (type II), had important role in seed and oil yields. It can be concluded that replicating the experiment, would possibly result in recommending adaptable and high yielding oilseed rape varieties for cold climates of the country.
