摘　　要：兰属(Cymbidium)植物作为重要的观赏花卉,是研究被子植物花器官分化的良好模式类群。目前,兰属植物的染色体进化研究十分受限,其物种形成和进化过程尚不清楚,部分种或变种仍缺乏着丝粒、端粒、核仁组织区等细胞学标记。本研究从常规的细胞学和分子细胞遗传学两个角度对兰属植物染色体的倍数性、核型、染色体行为、荧光原位杂交、表观遗传标记及分子标记等方面进行了综述,期望为兰属植物的系统研究和杂交育种提供理论参考,并为细胞学及分类学相关工作的研究提供基础。As an important ornamental flower,Cymbidium is a good model group for studying the floral organ differentiation of angiosperms.At present,studies on chromosome evolution of Cymbidium are very limited,and the process of speciation and evolution is still unclear.Some species or varieties still lack cytological markers such as centromeres,telomeres and nucleolar tissue regions.In view of this,the review summarized the progress in chromosome ploidy,karyotype,chromosome behavior,FISH,epigenetic markers and molecular markers of Cymbidium based on the conventional cytology and molecular cytogenetics,hoping to to provide theoretical reference for systematic study and cross breeding of Cymbidium,and provide basis for cytology and taxonomic research.
