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％。
The double haploid self-incompatibility lines Q2-1 and (W3-1 × M65-1-1) -1 obtained by using the free microspore culture technique were used as the parent materials to breed new varieties of Chinese cabbage Number 11. The variety of 60 days growth period, disease resistance, high yield, high quality, neat vegetables, suitable for planting in spring and autumn. Net vegetable yield 4113.4 ~ 5001.3kg / mu, compared with the control of early 89-8 yield 8.4% ~ 81.7%.
