长期以来,国内外都是利用自交不亲和系配制甘蓝杂交种,其亲本繁殖成本较高,亲本连续多年自交易发生生活力衰退,杂交率亦难达以100％。中国农科院蔬菜花卉研究所通过10多年研究,首次发现甘蓝显性雄性不育材料79—399—3,并研究明确控制不育性的主效基因为一对显性基因。利用微花粉植株自交、测交和回交,选育 For a long time, the domestic and foreign hybrid kale hybrids are made using self-incompatibility lines. The cost of breeding their parents is high. The parents’ viability declines for many years since the transaction, and the rate of hybridization is also hard to reach 100%. After more than 10 years of research, Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, the first discovery of male-sterile male-sterile cabbage 79-399-3, and the dominant gene controlling sterility as a pair of dominant genes. Using pollen plants selfing, cross test and backcross, breeding
