摘　　要：山药地下块茎肥大,营养价值高,种质资源丰富,但细胞遗传学研究相对滞后。本文从山药种类与分布、染色体数目及倍性、染色体核型等方面综述了我国山药细胞遗传学方面的研究现状,同时对细胞遗传学在山药种质创新及利用、遗传分析、育种工程等方面的发展前景进行了探讨,为今后薯蓣植物的品种改良及育种提供依据。Dioscorea opposita Thunb.has large underground tubers and rich nutritional value.Its germplasm resources have their own characteristics,but its cytogenetic research progress is slow.In this paper,the research status of Dioscorea opposita Thunb.cytogenetics was reviewed from the aspects of species and distribution,chromosome number,ploidy and chromosome karyotype.Meanwhile,the development prospects of cytogenetics in yam germplasm innovation and utilization,genetic analysis,breeding engineering and so on were discussed,which provided the basis for the variety improvement and breeding of Dioscorea opposita in the future.
