草坪草抗锈病遗传育种研究进展

Advances in genetics and breeding for rust diseases resistance in turfgrasses

锈病是草坪草上常见的一类气传真菌病害,主要危害禾草的叶片和叶鞘。本研究以主要的冷季型草坪草,如[高羊茅(Festuca arundinacea)、黑麦草(Loliumspp.)和草地早熟禾(Poa pratensis)]等,与暖季型草坪草,如[狗牙根(Cynodon dactylon)和结缕草(Zoysiaspp.)]为对象,综合国内外相关研究报道,对草坪草抗锈病性状的遗传与选育研究进展做了整理与述评,对草坪草抗锈病性状特征与种质评价的效果做了着重介绍,并展望了今后研究工作的重点和必要的技术途径。结合常规选育方法,总结了草坪草抗锈病性状分子连锁标记的开发与数量性状位点的研究进展,为进一步开展相关研究提供较为全面的研究背景资料。

Rust diseases occur on all turfgrass species which caused by the particular air borne rust fungus,symptoms of these diseases appear on the both sides and the sheath of leaves.Based on previous publications on the diseases,this review article discussed the research progress of rust diseases resistance made in cool-season grasses,like tall fescue,ryegrass,and Kentucky bluegrass,and warm-season grasses,like bermudagrass and zoysiagrass.The authors also figured out some important points in future research and necessary methods will be conducted.The authors focused on the characteristics and efficient of germplasm evaluation for rust diseases resistance in turfgrasses.Combined with conventional breeding methods,we summarized the development of the linkage molecular markers and quantitative trait locus QTL for rust diseases resistance in turfgrasses.The purpose of this paper was to provide a relative detailed research background information for further research.
