中国燕麦种质资源国外引种与利用

综述了中国从国外引进燕麦种质资源及其利用情况。经过长期努力,中国从28个国家引进29个物种的燕麦种质资源共计2099份,大大增加了中国燕麦种质资源的数量,丰富了中国保存燕麦种质资源的物种和遗传多样性。与此同时,利用国外燕麦种质资源改良和培育出了一批优良品种,极大地提高了中国燕麦生产水平。利用引进的燕麦野生资源,开展了燕麦种质创新、起源进化和遗传学研究,取得了显著进展。建议继续加强国外燕麦种质资源的引进,对野生燕麦进行深入鉴定评价和利用,同时加强燕麦种质资源国际合作研究。

Introduction and Utilization of Foreign Oat Germplasm Resources in China

The paper synthesized the progress in introduction and utilization of oat germplasm resources from foreign countries. Through a long period of efforts, China had introduced 2099 accessions of oat germplasm resources from 28 countries, covering 29 species of Avena genus. It has greatly increased the number of oat accessions and enriched the species and genetic diversity of oat conserved in China. Meanwhile, the introduced oat germplasm resources were used to develop a number of new varieties and enhanced the productivity of oat in China. The considerable progress has been made in utilization of the introduced wild species of oat for germplasm enhancement, studies on origin and evolution, and genetics of oat. It was suggested that the oat germplasm introduction from abroad should be strengthened. Priorities should be given to evaluate and utilize the wild oat germplasm resources. At the same time, the international collaboration on oat germplasm resources should be strengthened.
