Abstract: Cynodon dactylon(bermudagrass),is an internationally recognized warm-season turfgrass used for high quality pasture.There are abundant wild bermudagrass germplasm resources in China distributed throughout the south of the Yellow River Valley,however,evaluation and improvement of bermudagrass germplasm remains poor.This review describes research advances in the germplasm resources of bermudagrass in terms of distribution,biological characteristics,genetic diversity,stress resistance,and breeding.The problems and perspectives related to research in germplasm resources of Cynodon dactylon were also elucidated briefly.The purpose is to provide background information for the development and utilization of bermudagrass germplasm.

Key words: Cynodon dactylon, Germplasm resources, Genetic diversity, Variety, Breeding

摘要: 狗牙根(Cynodon dactylon(L.) Pers)既是应用最广泛的暖季型草坪草,也是优质牧草。我国拥有丰富的狗牙根种质资源,分布遍及黄河流域以南的广大地区,但我国的狗牙根种质资源评价与改良工作水平还很低。通过对狗牙根种质资源的分布、生物学特征、抗逆性、遗传多样性及育种等方面的研究进展进行系统概括和归纳,简要评述了狗牙根种质资源研究中存在的问题并展望其应用前景,以期为狗牙根种质资源的开发利用提供基础资料。
