摘要: 1979~1993年鉴定了由国际水稻研究所提供的稻瘟病圃材料3431份,白叶枯病圃材料1303份,褐飞虱圃材料2011份,获抗稻瘟病0级431份。1~2级137份、3级121份;白叶枯病1级214份、3级272份、5级301份;褐飞虱0级231份、1级374份、3级597份,表现抗性强、抗谱广,可作为抗源材料利用的有抗稻瘟病品种12份和抗白叶枯病与褐飞虱品种各8份。Abstract: 3431,1301,and 2011 IRRI-provided varieties from International Rice Blast, Bacterial Blight and Brown Planthopper Nurseries were determined from 1979 to 1993.The results showed that, the varieties from rice blast nursery,0.1-2.3 scale occupied 437,131 and 121 respectively;from bacterial blight nursery,1,3 and 5 scale occupied 214, 372and 301 respeltively;from brown planthopper nursery occupied 231,374 and 597 respectively,In determined varieties,12 from rice blast nursery, 8 from bacterial blight nursery and S from brown planthopper nursery have relative- ly strong and wide-ranging resistance which may be considered to be used as parent materials in rice breeding.
