【摘要】 用贵州农家品种筛选出的冬性特强抽薹特晚株系和不同生态型品种进行多亲复合杂交,其后代又利用设计出现的雄性不育株,隔代在大群体中使之充分异交,经多代集团性轮回选择,先育出5个具有不同生态特点的基础群体,而后再用不同的选育途径和方法育成常规品种、质核杂种和一代杂种等.此选育研究从1979年开始,至今已育出品种品系十几个,其中两个系统已通过省级审定,示范推广面积近10万hm~2.贵州省科委组织的专家鉴定和中国农科院科技信息中心查新的结论是:国内领先,优于国外同类品种等.更多还原

【Abstract】 The multiple crosses were carried out among the - overstrong - winterness - and - the - latest - bolting Chinese cabbage lines and different ecotype cultivars which were selected from the local cultivars in Guizhou province for many years. Their progenies were fully cross - pollinated with the male sterile plants that appeared according to plan in every two generations in big population. And 5 basal populations with distinctly morphological and e-cological characteristics were gained by group - recurrent selection for many generations. The population cullivars , gene - cytoplasmic hybrids and F₁ hybrids were bred by different methods. This research was started from 1979 and more than 10 cultivars （lines）, in which 2 ones were approved by the provincial government of Guizhou, were bred. The extended and demonstrated area in total was approximately 100,000 hm². The results of the experts identification organized by the Guizhou scientific and technological committee and information retrieval by Chinese academy of agricultural science were that these cultivars （lines） were in the lead in China and superior to the similar ones overseas.更多还原
