摘要: 黑麦草属(Lolium)和羊茅属(Festuca)包含冷季型牧草和草坪草等诸多重要草种, 如意大利黑麦草(L. multiflorum)、多年生黑麦草(L. perenne)、高羊茅(F. arundinacea)及草地羊茅(F. pratensis)。黑麦草产量高、适应性强、营养丰富、适口性好且消化率高, 可作为干草和青贮饲料, 是一种优质牧草。但由于其在我国的栽培受地理因素限制, 目前黑麦草在我国草牧业中所占比例很小。为提高黑麦草种植比例, 利用分子育种手段选育优良品种是我国黑麦草研究的重点方向之一。该文系统总结了黑麦草-羊茅复合体, 特别是黑麦草的研究进展, 包括分类与进化、分子标记开发、连锁图谱构建、重要农艺性状的数量性状位点(QTL)定位和全基因组关联分析(GWAS), 以及基因组测序、转录组分析、基因克隆和品种培育等, 并提出一些需要解决的生物学问题, 旨在为进一步加强黑麦草基础生物学研究和分子育种提供参考。

Abstract: The genera of Lolium and Festuca include many cool season forage grasses and turf species, such as Italian ryegrass (L. multiflorum), perennial ryegrass (L. perenne), tall fescue (F. arundinacea) and meadow fescue (F. pratensis). The ryegrass can be used as hay and silage, due to its high yield, broad adaptability, rich nutrition, good palatability, and high digestibility; and it was considered as a high-quality feed. But because its cultivation region in China is limited by geography factors, the current proportion of ryegrass in China’s grass pasture industry is still very small. In order to increase the proportion of ryegrass cultivation, the use of molecular breeding methods to breed excellent varieties maybe one of the key directions. In this review, we summarized recent progress in the Lolium-Festuca complex, especially in Lolium, including classification and evolution study, molecular marker development, linkage map construction, quantitative trait locus (QTL) and genome wide association study (GWAS) for important agronomic traits, genome sequences, transcriptome analysis, gene cloning and variety breeding. We also brought up some biological issues in Lolium species that need to be resolved, and try to provide some reference for further strengthening the basic biological research and molecular breeding of ryegrass.
