摘要
１９８３～１９９０年间，通过抗病性鉴定和常规育种选出的优良，不结球白菜高代自交系，经杂交选配，获得两个杂种优势强、综合经济性状优良．且抗病性强的组合：Ｊ（７８－０９）Ⅰ×Ｊ（７８－０９）Ⅱ（冬常青）、Ｊ（Ⅱ－１）×Ｊ（Ⅱ－２）（夏冬青），两者已广泛应用于生产，大面积推广，效益显著。
Two hybridized combinations of nonheading Chinese cabbage J78-09 Ⅰ×J78-09 Ⅱ (Dongchangqing)and JⅡ-1 × J Ⅱ-2 (Xiadongqing )showing high heterosis, fine economic characteristics, high disease-resistance and high yield were obtained by using generations' self-lines as parents, through routine breeding methods and with indoor and outdoor disease-resistance testings. The two hybridized combinations are already extensively used in commercial production and give fine economic results.
