摘  要:
为了解决小菘菜杂种优势利用上的杂交制种手段问题,设计定向转育方案,以核基因雄性不育系复等位基因遗传的奶白菜06SX110为不育源,采用连续回交转育性状,同时测交筛选不育基因型的方法,向小菘菜自交系Y05中转育雄性不育基因。结果表明,可育成具有100%不育株率的小菘菜核基因雄性不育系GMS4,用其配制并筛选出1个优良杂交组合。实现了雄性不育核基因与园艺学性状的同时转育。

摘  要:
The study was done in order to solve the crosses breeding problem in utilizing hybrid vigor of Greens Komatsuna. A directional transfer program was designed by using multiple allele inherited genetic male-sterile line 06SX110 as source of male sterility, and recurrent backcrossing was employed to transfer botanical traits, while the genotype was identified through test cross.Following the procedure, the male sterile gene was transferred to the target parent Y05. Results showed that a new male sterile line GMS4 with 100% male sterility was bred. GMS4 as the female parent, the excellent hybridized combination was finally obtained. The male sterility and other horticultural characteristics in Greens Komatsuna could be transferred simultaneously based on the method designed in the research.
