In order to evaluate the effect of sowing date on morphological characteristics and Chlorophyll content traits in rapeseed (Brassica napus L.) a study was initiated in 7931 in Omidieh with Factorial experimental based on Randomized Completely Block Design with 3 treatments such as three sowing date (7931.0202,7931.3202 and 7931.72202) , three cultivars of canola(Hyola 127,Hyola 920 and RGS 229) and four replications. The results showed that the effect of sowing date was significant at 7% level on Stem diameter, Plant height and Pod height but was not significant on chlorophyll. Cultivar had significant effect at 5% level on chlorophyll and did not showed significant difference on other traits. . Interaction effect between sowing date and cultivar did not showed significant difference on These traits.
