我国狗牙根种质资源研究进展

Research progress of the Cynodon dactylon germplasm in China

狗牙根(Cynodon dactylon)作为全球暖季型草坪草中坪用价值较高的草种之一,其生活力强,繁殖迅速,耐践踏,在我国不仅是应用广泛的优良草坪草之一,也是优良的固土护坡植物。制定科学的资源保护策略、促进其开发利用以及新品种的选育将具有重要的意义。本研究对我国狗牙根种质资源的用途、分布情况、遗传多样性以及育种进展进行了较全面的总结和探讨,分析了我国狗牙根种质资源研究目前存在的问题并提出了展望,以期为我国狗牙根种质资源的进一步深入研究和合理的开发利用提供一定的参考依据。

Cynodon dactylon,as one of the higher valuable lawn grasses in global warm-season turf grass,it has strong living ability,speedy fertility and high trampling resistance.In China,it is not only the fine lawn grass widely applied,but also a good plant in soil conservation.There were of great significance in constituting the scientific protected strategy,promoting its exploitation and utilization,and breeding new varieties.Based on previous studies,this research reviewed the utilization,distribution,genetic diversity and breeding progress of the C.dactylon germplasm in China.To provide reference for the further research and utilization of the C.dactylon germplasm,the problems of the C.dactylon current germplasm research was anlysed as well.
