为实现对稻飞虱的持续控制,江西省农科院植保所、中国水稻研究所研究人员合作,应用功能植物损失指数和田间产量损失率等指标,评价了江西省17个水稻品种对稻飞虱的耐害性水平。结果显示,陵两优268、中嘉早17、欣荣优5号和潭两优83等4个早稻品种的功能植物损失指数在45.45~74.93,显著低于感虫对照品种TN1的功能植物损失指数;陵两优268、欣荣优5号和潭两优83等3个品种的产量损失率较低,均在1%以下。湘优196和天
In order to achieve the continuous control of planthoppers, Jiangxi Academy of Agricultural Sciences Institute of Plant Protection, China Rice Research Institute of cooperation, application of functional plant loss index and field yield loss rate and other indicators of the evaluation of Jiangxi Province, 17 rice varieties of rice fly Louse resistance level. The results showed that the functional plant loss index of four early rice varieties, ie Lingliangyou 268, Zhongjiazao 17, Xinrongyou 5 and Tanliangyou 83 were between 45.45 and 74.93, significantly lower than those of the susceptible control strain TN1 Index; Yield loss rate of three varieties including Lingliangyou 268, Yanrong excellent 5 and Tanliangyou 83 were all lower than 1%.
