甘蓝型油菜胞质雄性不育系CMS22A的选育与遗传I.双低不育系CMS22A的选育及其败育类型研究
Journal of Henan Agricultural Sciences（2005）
Abstract
甘蓝型双低油菜CMS22A是河南省农业科学院棉花油料作物研究所利用384A中的雄性不育源、采用单株成对连续回交的方法育成的双低油菜细胞质雄性不育系.其突出表现为雄性不育彻底且遗传稳定,配合力高,抗病抗倒,品质优良.CMS22A属典型的败药型雄性不育系,雄蕊败育短缩至雌蕊基部,♂/♀<0.5,花药退化变小、无花粉.雌蕊发育正常,花瓣虽变小皱缩,但花瓣开张正常,可以正常接受外来花粉、受精结实.不育率稳定保持在99%以上.
