Abstract: Carex L. was a perennial herbaceous plant of the Cyperaceae family,characterized with strong shade tolerance,strong self-reproduction ability,perennation and abundant germplasm resources.Carex plants were playing an increasingly important role in landscaping,grass husbandry production,ecological restoration and other aspects. With the wide application of Carex,further exploring germplasm resources and breeding new cultivars has become the major objective,whereas genetic diversity studies are the basis. In this study,the progress of Carex genetic diversity researches at the morphological,cellular and molecular levels were described. Moreover,the application of genetic diversity analysis in cultivar breeding,germplasm classification,origin and phylogenetic relationship of species and genetic map construction were introduced. In the end,the prospect of genome development and new variety breeding of Carex were discussed to lay a foundation for studies on genetic breeding and further development and application in future.

Key words: Carex L., Genetic Characteristics, Morphological Level, Cellular Level, Molecular Level, Genetic Diversity

摘要: 苔草(Carex)为莎草科(Cyperaceae)苔草属(Carex L.)的多年生草本植物,具有耐荫、自繁能力强、多年生、种质资源丰富等特点,在园林绿化、草牧业生产、生态修复等方面发挥着越来越重要的作用。随着苔草属植物的广泛应用,种质资源进一步开发和新品种选育成为当前的重点,而遗传多样性研究是基础。本文综述了苔草属植物在形态、细胞及分子水平的遗传多样性研究进展。此外,还介绍了苔草属植物遗传多样性研究在新品种选育、品种鉴定、物种起源及亲缘关系、遗传图谱构建等方面的应用。最后对苔草属植物基因组开发、新品种培育进行展望,以期为今后苔草的遗传育种及进一步开发应用奠定基础。
