Abstract: 
To investigate the effect of planting date on canola (Brassica napus L.) growth period, yield, and yield components and to study the possibility of a correlation between these characters in three canola cultivars (Hyola 401, RGS003, and Pf 704), an experiment was conducted in an experimental field at Agricultural College of Shahid Chamran University of Ahwaz during 2003-4 cropping season. The experiment was designed as split plot planned as complete randomized blocks with three replications. Plots and sub-plots respectively consisted of four planting dates (November 16, December 6, December 26, January 15) and three cultivars.
Results indicated that with different planting dates, there were significant differences in seed yield and pods per plant at the probability level of %99. Significant differences were also found in seed per pod, oil contents, and protein percentages at the probability level of %95, but not in 1000 seed weight. Three cultivars exhibited considerable differences in the characters yield, pods per plant, and seed per pod at the probability level of %99 but not in 1000 seed weight, oil and protein percentages. Moreover, phenological traits like lengths of growth period, periods of planting date till the apperance of flower buds, lengths of flowering period, lengths of podding period, and grain filling differed significantly at the probability levels of %99 as the result of different planting dates and canola cultivars. Among the yield components, pod per plants was the trait with the highest correlation with yield (r=0.7), however, no significant correlation was found between 1000 seed weight and yield production which was highly correlated with all phenological characteristics mentioned above.
