通过实地考察收集等途径,从东南亚国家引进稻种资源662份,其中野生稻120份,栽培稻542份对栽培稻资源进行隔离检疫繁殖以及性状鉴定,获得足够种子并构建引进东南亚栽培稻资源数据库。从栽培稻种质中鉴定发掘出抗褐飞虱材料58份,抗稻瘟病材料9份,抗白叶枯病材料11份,耐盐材料12份。引进的稻种资源拓宽了我国水稻遗传基础,丰富了我国的稻种资源基因库,将在水稻育种及相关研究中发挥积极的作用。 Through field investigation and collection, 662 rice seed resources, including 120 wild rice and 542 cultivated rice, were introduced from Southeast Asian countries for isolation, quarantine and characterization of cultivated rice resources, sufficient seeds were obtained and the database of introduced cultivated rice resources in Southeast Asia was constructed . 58 cultivars of rice brown planthopper, 9 blast resistant materials, 11 bacterial blight resistance materials and 12 salt tolerant materials were identified from cultivated rice germplasm. The introduction of rice resources to broaden the genetic basis of rice in China and enriched China’s rice gene pool of resources, rice breeding and related research will play an active role.
