摘 要:本文通过时双丰系列甜菜多倍体品种的种性介绍及其系谱分析,揭示了双丰系列多倍体品种的遗传构成和血缘来源,双丰多倍体品种共有12个,参与亲本形成的血缘共有7个。利用天然多交逐级改良种性的逐级杂种优势利用育种技术构成了双丰系列多倍体的育种特色,建立平衡群体和改良平衡群体是双丰系列多倍体育种技术的理论依据。The performance of polyploid varieties of Shuangfcng seriea have been introduced andanalysed on its family,it has brought to light the genetic structure and the source of bloodrelationship,there are 12 cultivars of Shuangfeng series, the blood relationship have 7 in theirparents,we can use native polycross to improve the pcrformance of polyploid and heterosisapplied,this is the breeding charactcrs of Shuangfeng scries, and to establish the equilibriumpopulation and improved equilibrium population which were the theory bases for thepolyploid breeding of Shuangfeng series.
