摘要
Totaling 662 rice germplasms were collected from Southeast Asia,including 120 wild species and 542 cultivated rice plants.An information database of the collections was constructed after phenotype identification.Based on evaluation of cultivated rice,some germplasm resources were found to have good characteristics,including 58 accessions resistant to brown planthopper,nine accessions resistant to rice blast,eleven accessions resistant to bacterial blight,and twelve accessions with salt-tolerance.The introduced rice resources broaden genetic basis of rice and enrich rice genbank in China,which would play an active role in rice genetic research and rice breeding.
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。
