摘　　要：本研究对来源于全球22个国家的130份分子育种亲本材料,在福建省上杭县茶地上自然鉴定其田间苗瘟、叶瘟和穗颈瘟发病率,旨在筛选出稻瘟病抗性亲本,丰富现有的水稻品种资源。供试的130份水稻亲本材料中,高抗(HR)、抗性(R)亲本分别都占全部鉴定材料的11.5%,说明稻瘟病抗性资源丰富。但不同国家或地区存在的抗源丰富程度不同,在东南亚或南亚一些国家的抗源比较丰富,中国、日本、韩国等东亚国家的抗性材料相对较少。130 rice cultivars coming from the global rice molecular breeding program （GRMBP） were tested for the resistance to seeding, leaf, and spike blast in Shanghang, Fujian. The results showed that 11.5% of the tested cultivars performed high resistance and resistance to blast, respectively, means these cultivars in GRMBP is rich in re sistance to blast. There are much different in blast resistance for cultivars in different countries or regions. Some countries in the southeast and south of Asia have more blast resistant cultivars, while China, Japan and Korea in east of Asia, have less blast resistant cultivars in the GRMBP.
