甘蓝型 ( B.nap us)黄籽油菜 Y2 D56个株系及 950 11、宁油 10号、HDY18- 4、H970 84个品种 (系 )的黄籽和褐籽发芽率等性状比较分析表明 ,基因型对发芽率等性状有影响 ,粒色对发芽率等性状也有影响 ,一般褐籽优于黄籽。产生这种现象的原因可能与黄籽成熟度不够 ,种皮较薄有关。因此 ,在甘蓝型油菜黄籽育种中 ,要特别注意选择高质量的黄籽类型 The comparative analysis on the germination rate of yellow seed and brown seed of 84 varieties (lines) of B.nap us yellow Y2 D56 lines and 95011, Ningyou 10, HDY18-4, H970 showed that, Genotypes such as germination rate and other traits have an impact, the color of germination rate and other traits also have an impact, the general brown seed is superior to yellow seed. This phenomenon may be due to lack of maturity of yellow seeds, the seed coat is thin. Therefore, in yellow cabbage breeding Brassica napus, pay special attention to choose high-quality yellow seed types
