摘要:

结合物种的多个概念,综述了国内外苜蓿属植物分类的意义和混乱的现状,统计了我国13个苜蓿属物种的名称和特性,详细总结了全球约90个苜蓿属物种的名称、生活型、染色体数目、授粉方式和自然分布等,以及苜蓿属内14个组和10个亚组的划分、不同物种间的分子进化关系、苜蓿属的地理起源,并进一步解释了紫花苜蓿复合体内部不同亚种之间的遗传关系。提出了在深入理解物种概念的基础上鉴定苜蓿属物种的方法,建议广泛收集全球苜蓿属种质资源,采用分子进化等手段进一步理清苜蓿属内组间和物种间的进化关系,以期为今后的苜蓿属植物分类和紫花苜蓿杂交育种提供参考。

Abstract:

This review investigates the disordered status of the classificationof Medicago genus, both domestically and internationally. Several definitions of a taxonomic species were considered and the names and characteristics of 13 Medicago species in China are reported, together with a detailed summary of the names, life forms, chromosome numbers, pollination methods and natural distribution of about 90 Medicago species worldwide, including the classification of 14 sections and 10 subsections in Medicago. The molecular evolutionary relationships between different species, and the geographical origin of Medicago are discussed, and the genetic relationships between different subspecies in the alfalfa complex are further explained. This study puts forward a method of identifying Medicago species on the basis of deep understanding of the concept of species. A wide collection of global Medicago germplasm resources, aiming to further clarify the evolutionary relationship among different sections and different species by molecular evolution methods is proposed. This review provides a reference framework for future Medicago classification and alfalfa cross breeding.
