摘要: 狼尾草属(Pennisetum)牧草是热带、亚热带重要优质牧草,生物量高、抗逆性强、饲用价值优良,是缓解我国饲草供给不足的关键资源。目前我国审定狼尾草属牧草品种共17个,多适配南方生态区,北方抗逆高产品种匮乏,优质新品种选育需求迫切。本文综述了引种驯化、杂交育种、诱变育种等常规育种技术,以及分子标记辅助育种、基因工程育种等分子育种的研究进展,分析了自主不育系短缺、远缘杂交效率低、分子育种体系不完善等问题,并对种质资源挖掘、育种目标优化与新技术应用进行展望,为狼尾草属牧草遗传改良与产业化提供参考。

Abstract: Grasses in Pennisetum genus are important high-quality forages in tropical and subtropical regions, characterized by high biomass, strong stress tolerance, and excellent feeding value. They serve as a key resource to alleviate the shortage of forage supply in China. To date, 17 Pennisetum cultivars have been registered in China, most of which are adapted to the southern ecological zones, while there is a lack of stress-tolerant and high-yielding cultivars in northern China, highlighting an urgent need for breeding elite new varieties. This paper reviewed the research progress in conventional breeding techniques, including introduction and domestication, cross breeding, and mutation breeding, as well as molecular breeding approaches such as molecular marker-assisted breeding and genetic engineering. It also analyzed the existing problems, including the shortage of self-incompatible lines, low efficiency of distant hybridization, and an underdeveloped molecular breeding system. Finally, the paper discussed prospects for germplasm resource exploration, optimization of breeding objectives, and application of new technologies, aiming to provide a reference for genetic improvement and industrial development of Pennisetum forages.
