摘　　要：羊草是一种优质牧草,对发展我国优质草地畜牧业具有重要意义.以往研究对羊草生物学以及生理生态学进行了比较深入的探讨,但对于羊草分子生物学的研究起步较晚,进展也比较缓慢.近年来,随着分子生物学研究手段和技术的进步,以及羊草遗传改良的需要,人们在羊草遗传多样性、愈伤组织培养、酶蛋白分析以及基因克隆与转化等研究领域陆续开展了一些有益的尝试,并取得了重要的研究成果.结合科研工作的需要,对羊草分子生物学的最新进展进行了概述,并就亟需解决的问题进行了分析,提出了该领域今后的发展方向.As a kind of excellent herbaceous species, Leymus chinensis is very important for developing grassland stockbreeding. The biology and physiological ecology but little progress were made on molecular biology because of in L. chinensis have been studied in detail, the later start. Recently, with the advancement of molecular biological technology and methods and the necessity for genetic improvement of L. chihensis, many instructive experiments had been designed and great achievements had been achieved in the fields of the genetic diversity, callus cultivating, analyzing of enzymes and proteins, and cloning and transferring of genes in L. chinensis. The progresses on molecular biology in L. chinensis were summarized, the problems were discussed and the future development directions in this research field were proposed.
