In order to study Evaluation of qualitive and quantitive traits of canola, an experiment was conducted during 2011. The results from variance analysis indicated that regions of cultivation had significant effect on all of studied traits, except the content of proteins. Also Torbatjam region had better seed yield rather than Taybad. However, there were identical trends about seed yield changes in two regions, but there were significant differences between genotypes regard to seed production. As Hyola-401 and Mudena genotypes had the most and the least seed yield in both regions, respectively. Although, it is revealed that delay in cultivation lead to reduce most of agronomical traits such as seed yield. Also, the results from correlation coefficients indicated positive and significant relations between seed yield vs traits: number of subbranches, number of seed in pod, 1000 seed weight and oil contents, whereas negative and significant relation vs number of seed in pod, pod length, and protein contents. Altogether, according to the results, Hyola 401 genotype can be recommended to cultivate in two regions; in this way, the best sowing date is September in Torbat-jam region, whereas it can be delayed until October in Taybab region
