摘　　要：菊花为菊科菊属多年生植物,是世界上最重要的观赏花卉之一,兼有药用、茶用和食用价值。菊花具有适应性强、生长快、易栽培等特点,在全国各地已被广泛引种栽培,导致菊花栽培种、野生种及近缘种属混杂现象广泛存在,阻碍菊花育种和产业发展。本研究简要阐述了基于表型和DNA分子标记的菊花种质资源鉴定和分类、优异种质筛选、遗传多样性分析、遗传模型分析、遗传连锁图谱构建、目标性状的基因定位等方面的研究进展,以期为提高菊花种质资源利用效率和遗传改良提供参考。Chrysanthemum is a perennial plant of the genus Chrysanthemum in the family of Asteraceae.It is one of the most important ornamental flowers in the world,with medicinal,drinkable and edible value.Chrysanthemum has strong adaptability,grows quickly,easily cultivate,it has been widely introduced and cultivated all over the country.The mixed phenomenon of cultivated species,wild species and related species of chrysanthemum is widespread,which hinders the breeding and industrial development of chrysanthemum.This article reviews the research progress of phenotype and DNA molecular markers in chrysanthemum breeding research from the aspects of chrysanthemum germplasm identification and classification,excellent germplasm screening,genetic diversity analysis,genetic model analysis,genetic linkage map construction,gene mapping of the target traits.It provides a reference for the effective utilization of germplasm resources and the genetic improvement of chrysanthemum varieties.
