Table 1 Correlation among the physiological traits and seed oil content in 2010 at seed developmental stages: the value in the upper triangle is the Person correlation coefficient in canola high oil content line (HOCL) while the lower triangle is that in canola low oil content line (LOCL)

From: Chlorophyll and carbohydrate metabolism in developing silique and seed are prerequisite to seed oil content of Brassica napus L.
