| 摘 要： | 为了探索食用甘薯品种的选育方法,加快优良食用甘薯品种的选育进程。本研究对2001—2020年育成的22个食用型甘薯品种主要性状和亲本系谱进行了分析。结果表明：22个食用甘薯品种的平均鲜薯产量32689.0 kg/hm2,平均干物率28.1%。其中12个苏薯系列红心食用甘薯品种的平均胡萝卜素含量4.77 mg/100g鲜薯,10个宁紫薯系列紫心食用甘薯品种的平均花青素含量24.49 mg/100g鲜薯。系谱分析表明：苏薯系列红心食用甘薯品种基因源主要来自于美国品种,其中大多数品种都具有‘南瑞苕’血统,宁紫薯系列紫心甘薯品种基因源主要来自于日本品种,同时种质创新和桥梁亲本的应用也对紫心甘薯品种选育起到重要作用。外引资源和创新种质都是食用甘薯育种不可或缺的亲本来源,定向配组杂交是选育优良食用甘薯品种的主要方法。

| Abstract: | In order to explore the breeding methods of edible sweetpotato varieties and speed up its breeding programs, the main characters and pedigree of 22 edible sweetpotato varieties bred in 2001—2020 were analyzed. The results showed that the average fresh root yield of edible sweetpotato was 32689.0 kg/hm2. The average dry matter content was 28.1%. Among the 12 varieties of red-fleshed sweetpotato, the average carotene content was 4.77 mg/100g fresh root. The average anthocyanin content of the other 10 varieties of purple-fleshed sweetpotato was 24.49 mg/100g fresh root. The pedigree analysis showed that the genetic resources of red-fleshed sweetpotato varieties were mainly from American varieties, mostly with family lineage of ‘Nancy Hall’. The genetic resources of purple-fleshed sweetpotato varieties were mainly from Japanese varieties. Meanwhile, germplasm innovation and application of intermediate materials also played an important role in the breeding of purple-fleshed sweetpotato varieties. External resources and innovative germplasm are both indispensable parent resources for edible sweetpotato breeding. Directional hybridization is the main method for breeding good edible sweetpotato varieties. |
