摘要
垂穗披碱草(Elymus nutans)是多年生禾本科披碱草属植物,产量高,适口性好,抗逆性强,具有发达的须根,在我国的生态建设和畜牧业发展中发挥着重要作用。但由于育成品种不足,限制了垂穗披碱草的推广与利用。目前国内审定通过的国审垂穗披碱草品种均为野生栽培种,分别为康南垂穗披碱草(Elymus nutans Griseb.‘Kangnan’)、康北垂穗披碱草(Elymus nutans Griseb.‘Kangbei’)、阿坝垂穗披碱草(Elymus nutans Griseb.‘Aba’)、康巴垂穗披碱草(Elymus nutans Griseb.‘Kangba’)和甘南垂穗披碱草(Elymus nutans Griseb.‘Gannan’)。本文基于垂穗披碱草在抗逆性、生产性能及遗传多样性等方面的研究成果进行综述,并对未来可能开展的研究进行展望,以期为垂穗披碱草进一步的研究与利用提供参考。
Elymus nutans is a perennial grass Elymus plant with high yield,good palatability,strong resistance,and developed fibrous roots.It plays an important role in China's ecological construction and animal husbandry development.However,due to the lack of bred varieties,the promotion and utilization of Elymus nutans are limited.At present,the nationally approved Elymus nutans varieties approved in China are all wild cultivated species.They were Elymus nutans Griseb.'Kangnan',Elymus nutans Griseb.'Kangbei',Elymus nutans Griseb.'Aba',Elymus nutans Griseb.'Kangba'and Elymus nutans Griseb.'Gannan'.In this paper,the research results of Elymus nutans in stress resistance,production performance and genetic diversity were reviewed,and the possible future research was prospected,in order to provide reference for further research and utilization of Elymus nutans.
