Abstract: Two lines of rapeseed with high and low oil contents respectively which have the same genetic background were used to study the dynamic changes of oil-content, glucose 6-phosphate dehydrogenase (G6PDH) activity, and phosphatidate phosphatase (PPase) activity during seed formation, and the correlation between enzymes and oil content in Brassica napus was analysed. The results showed that Oil content, G6PDH activity, and PPase activity increased gradually and reached the peak at 24–31 d after flowering. Significant correlation between two lines in oil content, G6PDH activity and PPase activity were existed; G6PDH and PPase activities were significantly correlated with oil content. From the results above, we can come to the inference that G6PDH and PPase are the key factors affecting oil content.

Key words: Brassica napus, Oil content, Glucose 6-phosphate dehydrogenase, Phosphatidate phosphatase
