摘　　要：豆科牧草是饲草的重要组成部分,也是支撑畜牧业发展、尤其是乳产业的重要基础。我国豆科牧草育种研究基础薄弱,干草和优质草种依赖进口,是我国畜牧业发展的短板之一。因此,加强豆科牧草的育种,尤其是当前发展迅速的生物技术育种,是促进我国草业发展和“弯车道超车”的重要途径。由于我国优质土地主要用于粮食生产,畜牧业主要分布在自然气候条件恶劣的地区,因此,我国草产业对抗逆性强的优质牧草品种极其依赖。鉴于生物技术育种的巨大潜力,本文就豆科牧草组织培养体系、遗传转化方法及近年来豆科牧草在抗生物、非生物胁迫等方面的研究成果加以综述,并对未来研究方向进行展望。Legume forages are an important part of forage and an important basis to support the development of animal husbandry,especially the milk industry.The research foundation of legume forage breeding is weak,and the use of hay and high-quality grass species depends on import,which is one of the shortcomings in the development of animal husbandry in China.Therefore,strengthening the breeding of legume forage,especially the breeding of biotechnology,is an important way to promote the development of the grass industry and“overtaking in curved lanes”.As high-quality land in China is mainly used for grain production,and animal husbandry is mainly distributed in regions with harsh natural climate conditions,such as northwest and north China,the grass industry in China is extremely dependent on high-quality herb varieties with strong stress resistance.Given the great potential of biotechnology breeding,in this study,tissue culture systems,genetic transformation methods,and recent achievements in research on the resistance to biotic and abiotic stresses of legume forages were reviewed,and future research directions were proposed.
