老芒麦种质资源研究进展

Research Progress on Elymus sibiricus Linn.Germplasm Resources

老芒麦是欧亚大陆广布种,在我国也有着丰富的野生资源,由于其优良的牧草品质和强抗逆性,在我国高寒地区畜牧业发展和生态建设中发挥着重要作用。目前,各学者对老芒麦种质的研究逐步深入和系统化,本文综述了老芒麦生物学特性、生态分布、遗传多样性、品种选育、栽培与利用等方面研究进展,并提出研究展望,以期为老芒麦的综合利用提供参考。

Elymus sibiricus is a widely distributed species in Eurasia,and also has abundant wild resources in China.Because of its excellent forage quality and strong resistance,it plays an important role in the development of animal husbandry and ecological construction in alpine regions of China.At present,the researches on the germplasm of Elymus sibiricus are gradually deep and systematic.In this paper,the biological characteristics,ecological distribution,genetic diversity,variety breeding,cultivation and utilization of Elymus sibiricus were reviewed,and the research prospect was put forward in order to provide reference on further utilizing the germplasm resources of Elymus sibiricus.
