苜蓿作为平常研究的首选试材打下了坚实的基础。通过基因工程技术对其进行遗传操作，不仅可以对苜蓿本身加以改良和创新, 还可以为其它豆科植物在细胞水平上的遗传操作提供可靠的理论依据和有效途径。综上所述，随着生物技术在苜蓿研究领域的不断发展与应用，人们经过数十年不懈的努力，在提高牧草种子及饲草产量、改良饲草品种、增强品种抗性及适应性等方面已取得了丰硕的成果。但与其它重要农作物玉米、水稻、小麦等研究工作相比，苜蓿基因工程仍属于一个新生事物。我们应该广泛借鉴其它植物研究中的生物技术手段，加强研究力度，深入研究程度，使生物技术为苜蓿的遗传改良及产业化生产开辟更为广阔的途径，也使苜蓿基因工程自身的研究成果为其它植物的遗传转化研究积累经验。 参考文献：
