| 摘 要： | 披碱草属Elymus牧草分布广泛,种类繁多,广义的披碱草属包括近150个种,而在我国,则比较接受狭义披碱草属的概念,即有12余种.披碱草属牧草为中生-旱中生多年生优良牧草,是草原和草甸的重要组成部分,饲用价值极高.该属是禾本科小麦族中非常重要的一个类群,它具有麦类作物所缺乏的抗病、抗虫、抗旱、耐盐等优良抗逆基因,是现代麦类育种的重要种质资源.在前人研究的基础上,对国内外披碱草属种质资源的系统学分类、分布情况、遗传多样性研究进行了总结和探讨,以期为披碱草属资源的进一步研究利用提供参考依据.

| Abstract: | Elymus is the largest genus in the grass tribe Triticeae(Poaceae).Approximately 150 perennial and polyploid species are wildly distributed throughout the world.Elymus includes many economically important forage grasses as well as species with agronomically valuable characters,such as stress tolerance,disease resistance and wide adaptation.These traits can be transferred to cereal crops like wheat,barley,and rye through gene introgression.The great number of species in the genus creates further problems for making recommendations on preservation strategies.So studies of genetic diversity in these species are hence of primee importance. |
