摘要: 牧草育种工作是草牧业可持续发展的重要基础,目前除了应用传统育种的方法外,应用分子育种方法也取得一些突破性进展,特别是在抗逆性分子育种研究上取得了一定的实际性成果。株型是综合的农艺性状,是影响植物群体结构及产量形成的重要性状。现在株型在一年生作物株型分子机理及调控网络等方面已进行了深入系统的研究,而对于牧草株型调控机理研究颇少,大多研究是在与产量相关性状及其基础性分子育种等方面。针对影响植物株型形成因素及其机理进行了归纳总结,并对牧草株型性状相关研究进展进行了综述,最后简要评述了当前在牧草株型育种研究上所存在的关键问题,提出了相关建议,并指出可借鉴作物株型育种前沿研究方向制定牧草株型育种的研究策略。

Abstract: Forage grass breeding is an important foundation for sustainable development of forage industries. At present, in addition to conventional breeding methods, molecular breeding methods have also made some breakthroughs, especially in breeding for stress resistance. Plant architecture is an important agronomic trait of plants, and it is an important trait that affects plant colony structure and yield formation. Historically, the molecular mechanisms and regulatory networks of plant architecture in annual crops have been systematically studied, but there are fewer studies on the mechanisms governing plant architecture in forage grasses. Most of the extant studies deal with yield-related traits and basic molecular breeding. In this paper, the factors influencing the formation of plant architecture and their mechanism are summarized, and the research progress in forage grass plant architecture traits is reviewed. Lastly, the current key issues in forage plant architecture research and breeding are briefly reviewed, and some suggestions are put forward. It is concluded that the research strategy for forage plant architecture modification through breeding can be developed by referring to the frontier research directions of the crop of interest.
