- 摘要:
- 为促进甘蓝型油菜品种培育及品质改良，以9份甘蓝型油菜为材料，分别研究了在冬油菜区和春油菜区，套袋自交、自由授粉两种授粉方式对油菜品质性状的影响。结果表明，自由授粉的含油量较套袋自交高4.31百分点，春油菜区含油量较冬油菜区高3.81百分点；套袋自交的蛋白质含量较自由授粉高3.31百分点，冬油菜区蛋白质含量较春油菜区高2.59百分点；冬油菜区不饱和脂肪酸含量高于春油菜区，套袋自交不饱和脂肪酸含量高于自由授粉；冬油菜区芥酸、硫苷含量分别较春油菜区低1.08百分点和1.92 μmol·g-1。因此通过测定不同生态区油菜品质性状并进行比较，可以在春油菜区选育高含油量油菜种质资源，在冬油菜区选育高蛋白、高不饱和脂肪酸油菜种质资源。穿梭育种可实现春、冬油菜区优势互补，培育出品质性状优良的油菜品种。
- Abstract:
- In order to promote the breeding and quality improvement of Brassica napus varieties, the quality traits of rapeseed was studied under pollination methods, bagging self-pollination and free pollination, in the winter rape area and the spring rape area with 9 samples of Brassica napus. The results showed that the oil content of free pollination was 4.31 percentage points higher than that of bagging self-pollination, and the oil content of spring rapeseed area was 3.81 percentage points higher than that of winter rapeseed area. And the protein content of the bagging selfing was 3.31 percentage points higher than that of free pollination, and the protein content of winter rapeseed area was 2.59 percentage points higher than that of spring rapeseed area. The content of unsaturated fatty acids in winter rapeseed area was higher than that in spring rapeseed area, and the content of unsaturated fatty acids in free pollination was lower than that in bagging self-pollination. The erucic acid & glucosinolate content in winter rapeseed area were 1.08 percentage points and 1.92 μmol·g-1 lower than that in spring rapeseed area. Therefore it’s possible to select high oil content rapeseed germplasm resources in the spring rape area and high protein, high unsaturated fatty acid rapeseed germplasm resources in the winter rape area through determinating and comparing the quality traits of rapeseed in different ecological zones. The shuttle breeding can realize complementary advantages between spring and winter rapeseed areas, it’s of reference significance for cultivating varieties with excellent quality traits.
