摘　　要：稻飞虱是水稻上的主要害虫之一,抗虫品种的应用是防治稻飞虱最经济有效的方法。为实现稻飞虱的持续控制,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 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 3个品种的产量损失率较低,均在1%以下。湘优196和天优998两个晚稻品种的功能植物损失指数分别为71.46和77.19,也显著低于感虫对照品种TN1的功能植物损失指数;收割测产结果显示,湘优196、五丰优淦3号、天优998和庆丰优7798 4个品种的产量损失较低,其产量损失率在9.02%~13.68%。上述结果表明陵两优268、欣荣优5号、潭两优83、湘优196、五丰优淦3号、天优998和庆丰优7798等水稻品种对稻飞虱具有较强的耐害性,值得在生产上更加广泛地推广应用。Rice planthopper is one of the most serious insect pests of rice,application of resistant varieties is the most cost-effective method for controlling rice planthoppers. Aiming at sustainable controlling of rice planthoppers,the tolerance characteristics of 17 rice varieties planted in Jiangxi Province were analyzed using the functional plant loss index（ FPLI） and the yield loss rate. The results were as follows. The FPLI of 4 early rice varieties（ Lingliangyou 268,Zhongjiazhao 17,Xingrongyou 5 and Tanliangyou 83） ranged from 45. 45 to74.93 and was significantly lower than that of susceptible rice variety TN1.The yield loss rates of Lingliangyou268,Xingrongyou 5 and Tanliangyou 83 were lower than 1%. The FPLI of 2 late rice varieties（ Xiangyou 196 and Tianyou 998） were 71.46 and 77.19,respectively,significantly lower than that of susceptible rice variety TN1.The yield loss rates of Xiangyou 196,Wufengyougan 3,Tianyou 998 and Qingfengyou 7798 were from9.02% to 13.68%.These results indicated that Lingliangyou 268,Xingrongyou 5,Tanliangyou 83,Xiangyou 196,Wufengyougan 3,Tianyou 998 and Qingfengyou 7798 exhibit stronger tolerance to rice planthoppers and can be planted more widely.
