摘要
本研究以中籼、中粳稻为对象，对稻曲病为害产量损失及精米下降率进行了考查。结果表明，在参试的５个中籼、粳稻品种（组合）中，稻曲病对粳稻的为害程度高于籼稻。对参试的３个中籼稻品种（组合）的为害程度基本相似。
The yield loss of five semilate rice varieties (line) including three norglutinous rice and two keng rice varieties damaged by Ustilaginoidea virens and their decreasing ration of milled rice were investigated The results showed that the damage degrees of norglutinous rice varieties (line) were heavier than that of keng rice varieties (line) The damage degrees among the norglutinous rice varieties (line) were almost similar, so were between the keng rice varieties (line) Their modles of damage degree and decreasing ration of milled rice had also been established, respectively
