在抗芜菁花叶病毒和霜霉病研究工作的基础上，利用杂种优势育种技术，以ＳＷ－１３自交不亲和系为母本，Ｖ－１２６和Ｘ－１８９自交系为父本，选育出综合性状优良的矮抗五号和矮抗六号新品种。其特点：（１）丰产：生产试验平均产量分别达５７．２和６３．６ｔ／ｈｍ２，比对照矮抗一号分别增加１２．８％和２５．３％；（２）抗病：两品种ＴｕＭＶ、霜霉病、黑斑病人工鉴定病情指数分别为４．０１（ＨＲ），１２．０９（Ｒ），１２．９６（Ｒ）和１．５４（ＨＲ），９．１７（ＨＲ），２３．４２（Ｒ）；（３）优质：叶片重／叶柄重分别比对照提高１３．５％和２５．０％，且有机酸含量低；（４）耐热：热害指数分别比对照矮杂一号（４２．５０）降低了１００％和２７８％。
Based on the research work on anti-turnip mosaic virus and downy mildew, SW-13 self-incompatibility line was used as female parent and V-126 and X-189 inbred lines as male parent , Bred a good comprehensive traits of short resistance on the 5th and short resistance on the 6th new varieties. Its characteristics: (1) High yield: the average yield of production test reached 57.2 and 63.6t / hm2, respectively, which increased by 12.8% and 25.3% The disease index of TuMV, downy mildew and black spot were 4.01 (HR), 12.09 (R), 12.96 (R) and 1.54 (HR), 9.17 23.42 (R); (3) high quality: the leaf weight / petiole weight increased by 13.5% and 25.0% respectively compared with the control, and the content of organic acids was low; (4) Heat tolerance: Zumba (42.50) decreased by 100% and 278% respectively.
