Abstract

In order to study response of the seed yield and yield components of CANOLA genotypes to delay in planting, an experiment was conducted as split-plot in randomized complete block design with three replications, during two cropping seasons in zahak Agricultural Research station. Study factors were consisted four sowing dates (Nov 1th, Nov 16th, Dec 1th and Dec 16th as main-plots, and four spring rapeseed genotypes (RGS003, Hyloa401, pp-308/8 and pp-401/15E) as the sub-plots. The Results of combined analysis indicated that planting date and genotype had significant effect on seed yield and traits other, but the effect of year only was significant on oil percent, oil yield and day to initial flowering. With delay in planting, showed decreasing significantly the number of silique in plant, number of seed in silique, weight of 1000 grain, plant height, oil yield and seed yield. The first planting date (Nov 1th) with mean 2989 kg/ha had the highest seed yield and the lowest seed yield obtained with 39 percent decreasing in fourth planting date (Dec 16th). Hybrid Hyola 401 with mean 2701 kg/ha and RGS003 with mean 2453 kg/ha produced maximum seed yield between genotypes. The results of simple correlation of measured traits showed that between yield components, number of silique in plant and number of seed in silique with coefficients (r=0.82** and r=0.62**) and between other traits, oil yield and day to initial flowering with coefficients (r=0.98** and r=0.59**) had most positive correlation with seed yield, respectively. Based on the results, it can be concluded that planting in early Nov and use of hybrid Hyloa401 and RGS003 cultivar was recommendable in Sistan region.
