摘要
概述了2000～2004年在张掖市甘州区、高台县、民乐县雄性不育单粒型甜菜制种的成功经验;提出了雄性不育单粒型甜菜制种技术规程;建立了高产优质的良繁体系与基地。其制种产量可达到1500～3000kg/hm2,发芽率达到国家行业标准2级以上。
The CMS monogerm sugarbeet seed was successfully bred at Ganzhou region, Gaotai and Minle county in the Gansu province from 2000 to 2004. The reproductive techniques regulations, the breeding system and the base of the sugarbeet seed with high yield and quality were found.
