摘要
以采用游离小孢子培养技术获得的双单倍体自交不亲和系Ｑ２－１及（Ｗ３－１×Ｍ６５－１－１）－１为亲本材料，选育出早熟大白菜新品种豫白菜１１号。该品种生育期６０天，抗病、丰产、优质，菜型整齐，适于春、秋两季种植。净菜产量４１１３．４～５００１．３ｋｇ／亩，比对照新早８９－８增产８．４％～８１．７％。
Chinese cabbage Yubaicai 11 was developed from double haploid lines parents “Q2-1×(W3-1×M65-1-1)-1”,which respectively was rapidly gained from Chinese cabbage varieties at home and abroad by isolated microspore culture technique. This variety needs 60 days from sowing to harvest,and has good characteristic of disease resistance,high yield,good quality,uniform head and adaptation of planting in spring and in early autumn.The yield is about 61 700～75 020 kg/hm 2,8.4%～81.7% higher than the check(Xinzao 89-8).
