| 摘 要： | 目的:通过对不同来源地区的薯蓣属种质资源的植物学性状观测、统计和分析,为薯蓣种质资源的鉴定、分类和遗传改良提供依据.方法:采用大田栽培的方法,对薯蓣植株的24个性状分别进行定性观察或定量测定,分别进行主成分分析和聚类分析,对薯蓣种质的遗传形态变异进行研究.结果:94份薯蓣种质在24个测定的性状上变异非常丰富,叶片大小和根茎变异均较大.24个性状中前7个性状特征值的累积贡献率达80.957％.聚类分析把94份薯蓣属植物分为4个类群,分别属于薯蓣、褐苞薯蓣、山薯和参薯.结论:薯蓣种质间存在较大的形态变异.种质鉴定要重点关注叶片大小和根茎的性状. |

| Abstract: | Objective: Botanical characters of germplasm resources of Dioscorea were observed and compared, which could to offer reference for its genetic improvement, germplasm resource identification and classification. Method: Based on field cultivation, twenty-four morphological traits of ninety-four Dioscorea germplasm resources were observed or determined. And the morphological differences among germplasm resources were compared by principal component analysis and cluster analysis. Result: There were ample morphological diversity in the twenty-four traits, in especially in leaf size and tuber characters of the ninety-four Dioscorea germplasm resources. The first seven principal components which accounted for 80.957% of total variance were extracted from the principal component analysis. The ninety-four germplasm resources could be divided into four clusters, which belonging to Dioscorea opposite, D. persimili, D. fordii and D. alata respectively. Conclusion: There were large morphological variation among germplasm resources on Dioscorea. Identification of germplasm resources of Dioscorea should focus on leaf size and tuber characters. |
