摘　　要：现代生物技术在花椰菜遗传育种工作中得到广泛应用。目前已经建立起离体再生与单倍体诱导技术体系;利用分子标记技术对花椰菜种质资源进行遗传多样性分析,并绘制了主要花椰菜品种核酸指纹,为品种DUS测试、新品种保护以及种质资源评价利用提供重要依据;已经鉴定与分离出与抗性、品质和产量相关基因,建立了稳定遗传转化技术体系。本文还对生物技术在花椰菜遗传育种中的进一步应用进行了讨论。The modern biotechnology was widely applied in cauliflower genetics and breeding in recent years. The in vitro regeneration and haploid induction system was established. The molecular marker systerms were em- ployed to anlysize genetic diversity and construct DNA fingerprinting of the cauliflower germplasm, which provide important evidences for cultivar identification, breeder＇s right protection and germplasm evaluation and ultilaztion. Several genes conditioning resistances, quality and yield were identified and isolated. A high efficient system of genetic transformation has been established. The further application of biotechnology in cauliflower genetics and breeding was also discussed.
