摘要
借助对牡丹种间、种及品种间、品种间的亲缘关系在同工酶生化标记、分子标记及基因序列测定等分子手段方面的研究进行了综述.认为在肉质花盘亚组的2个种没有参加栽培牡丹的形成,革质花盘亚组中除四川牡丹以外的种都参入了栽培牡丹形成方面的研究结果一致.在牡丹种间、四川牡丹与同一亚组其他种间、四川牡丹与栽培品种间关系方面的研究结论还存在分歧,品种间关系的研究还比较少.建议针对研究对象和研究目的选择合适的分子研究手段并试用新的分子标记或基因测序方法,加强种内不同居群间关系的研究、种与品种、品种与品种间亲缘关系的研究、分子标记辅助选择育种与核心种质构建研究等.
The documents of the researches on the relationships between Chinese tree peony species, between species and：cultivars, and between cuhivars carried out by isozyme biochemical markers and DNA molecular markers and gene sequence analysis were reviewed. It was found that some conclusions that the two species in Subsect Delavayanae have not been involved in the cultivars＇ formation and all the species except Paeonia decomposita in Subsect Vaginatae have been found to be related to the cultivars＇ formation were the same; and other conclusions on the relationships between species, P. decomposita and other species in the same subsect, as wellP, decomposita and cuhivars were different; the studies on the relationship between the cultivars were rare. In order to evaluate tree peony germplasm resources correctly and set up a base for breeding new cultivars with self-owned intellectual property, it is suggested that suitable molecular markers and new methods should be selected according to different research objects and goals; the research on the relationships between different populations, between species and cultivars, between cuhivars should be enhanced; the studies on molecular marker-assisted selection breeding and the construction of the core collection should be strengthened.
