转基因抗虫油菜品系选育和性状研究

Breeding and Agronomic Characters of Transgenic Insect resistant Brassica napus Lines

为选育优质抗虫油菜新品系 ,在 Bt毒蛋白基因成功地转化到甘蓝型双低油菜品种湘油 13号后 ,对其植株性状、农艺性状和品质性状进行筛选 ,获得稳定的转 Bt基因油菜品系 .该品系除前期叶片稍大、叶色稍淡、苗期抗虫性较强外 ,其他性状与湘油

The transformants were selected according to the morphological, agronomic and quality characters after Bt toxic protein gene had been transferred successfully into double low rapeseed (Brassica napus) cultivar Xiangyou 13.The stable transgenic rapeseed lines were bred. The new lines were identical to the recipent parent Xiangyou 13 except slightly larger and lighter leaves at the early stages and stronger insect resistance at the seedling stage.
