建国后,各地有很多农业科学研究单位利用大白菜品种间杂交培育新品种,或利用杂交一代的优势,提高大白菜产量。据报导,通过品种间杂交已培育出不少优良品种,如中国农业科学院果树研究所,用兴城大矬菜一号与大麻叶、小包头等品种杂交培育出跃进一号大白菜;浙江农业大学用北京白口与天津绿杂交培育出浙江白口及浙江绿两个新品种,河北省石家庄地区农业科学研究所用正定大桩与兴城大矬菜杂交培育出抗 After the founding of the People’s Republic of China, many agricultural scientific research units around the country have used cabbage varieties to breed new varieties or take advantage of the hybrid generation to improve the yield of Chinese cabbage. It has been reported that many excellent cultivars have been bred through interbreeding among varieties. For example, Institute of Pomology, Chinese Academy of Agricultural Sciences, with Chinese cabbage University of Beijing with white and Tianjin green cross bred Zhejiang white breed and Zhejiang green two new varieties, Shijiazhuang, Hebei Province Institute of Agricultural Sciences with positive large pile and Xingcheng big bream hybrids breeding
