Abstract

In order to determine the most important phenological traits influencing the increase in seed yield and their relationship with yield and yield components in Spring cultivars of canola, a factorial Split plot experiment was conducted based on randomized complete block design with four replications in 2013-2014 growing season in the Research Field of Gonbad Kavous University. Treatments included four canola cultivars (C1= Hyolla401, C2= Zarfam, C3= Hyolla308 and C4= RGS003), two Planting dates (D1= 20 November and D2= 30 December) and three levels of nitrogen fertilizer (N1= zero, N2= 50% and N3=100%). The results showed significant differences in seed yield and other traits. The highest yield in the RGS003 (4. 4ton ha-1) planted on 20 November and the lowest in Hyolla308 (1. 1ton ha-1), were observed using nitrogen fertilizer and in this respect they were divided into three groups: high yielding (RGS003), medium (Hyolla401 and Zarfam) and low (Hyolla308). The maximum Seed filling rate (6. 1g/day) for the treatment RGS003 and 100% of the recommended nitrogen fertilizer and lowest (3. 7g/day) the date of 30 November was Hyo1la 308. In addition, on the date of 30 December, Hyolla308 lowest seed weight (3. 52g) with 100% nitrogen fertilizers, and RGS003 had the highest seed weight (4. 04g), respectively. Seed yield except in the days to flowering (r=0. 70**) and 1000 seed weight (0. 19g) had a significant positive correlation with the other traits.
