【摘要】 随着我国草坪业的快速发展,草坪草遗传育种工作越来越受到人们的关注。高羊茅为很重要的多年生冷季型草坪草,生物技术在其品种改良中具有很大的应用潜力。本文对高羊茅植株再生体系的建立及遗传转化方面的研究进展进行了综述,介绍了国内外高羊茅遗传转化的历史和现状。高羊茅再生体系的建立主要从外植体的选择和不同途径两个方面来阐述,而遗传转化部分则从不同的方法来说明。对高羊茅转基因研究中存在的问题和前景作了讨论。更多还原

【Abstract】 With the rapid development of turfgrass industry in our country,more and more attentions are paid to the genetic breeding of turfgrass. Biotechnology has great application potential in varietals improvement of tall fescue,which is commonly grown as cool-season turf grass in the temperate region. The establishment of tall fescue regeneration and genetic transformation systems was summarized. Meanwhile,the historical and present situations of tall fescue breeding are introduced. The part of tall fescue regeneration was expounded from different explants and approaches. While,the part of genetic transformations was expounded from different means. At last,problems and prospects of genetic transformation of tall fescue are discussed.更多还原
