Stage of maturity at harvest is one of the most important factors that can influence the quality of seeds. This research was carried out in 2008- 2009 to evaluate the development of physiological seed quality in three winter oilseed rape (Brassica napus L.) cultivars (Modena, Opera and SLM046). Seeds were harvested serially in 9-10 stages during their development and maturation. Maximum seed weight (mass maturity) was achieved at 48-54 days after flowering, when seed moisture content was 41-50%. However, maximum seed quality as measured by seed viability, germination percentage, germination rate and seedling dry weight was obtained 10 to 22 days after mass maturity. Thereafter, seed quality of all cultivars was started to decrease, due to ageing. Maximum germination rate of SLM046 and maximum seedling dry weight of Opera were significantly higher than those of other two cultivars. These variations in seed quality parameters were attributed to differences in genetic constitution among oilseed rape cultivars. It was concluded that high quality seeds of winter oilseed rape cultivars could be produced with 14-16% moisture content, which is suitable for direct and mechanical harvesting, threshing and storage without further drying.
