摘　　要：本文通过对双丰系列甜菜二倍体品种的种性介绍及其系谱分析，揭示了双丰系列二倍体品种的血缘组成。截止目前为止，共育成１６个双丰系列二倍体品种，参与其亲本构成的血缘共有９个。天然多交的综合种合成和雄性不育利用的单交种组合配制是双丰系列甜菜二倍体品种选育的主要技术路线。丰富的遗传构成和血缘来源奠定了双丰系列二倍体品种的“适应性广、稳定性强”的基固基础。逐级杂种优势利用和创造改良平衡群体是双丰系列甜菜品种的育种技术特色。The composition of consanguinity in diploid varieties were announced with the introduc- tion of varietal characters and pedigree analysis on diploid varieties of Shuangfeng series. Upto now,16 diploids of Shuangfeng series were bred,there were 9 of the consanguinity of par- ents. Breeding techniqties of Shtiangfeng diploid varieties were synthetic by natural and re- peated crossing to get collective species, MS line used and the combinations of interlinear hy- brid formulated,this is the genetic base for Shuangfeng diploid to keep the“wideadaptability,high stability”,this is the characteristic of breeding technique for Shuangfengseries with heterosis utilization by degrees and improving equilibrium population.
