摘要： 评价了来自中国的13个粳稻品种、11个籼稻品种、13个杂交稻组合，以及11个热带粳稻品种的杀卵作用和拒食抗性。具有杀卵作用的品种仅见于粳稻品种。测试的13个粳稻品种中，4个表现出明显的杀卵作用。重新评价了来自中国不同省份的42份粳稻和43份籼稻对白背飞虱的抗性。10个粳稻(约占24%)具有杀卵抗性，卵死亡率为53%~100%；95%以上的籼稻品种中，白背飞虱的卵死亡率低于30%；来自浙江的4个粳稻品种明显地抑制白背飞虱的取食。浙江的21个粳稻地方品种对白背飞虱拒取食和杀卵作用表现出独立性和连续变化。三千黄、长红稻和矮秆稻具有杀卵抗性，鸡脚黄和麻雀青具有拒取食抗性。这些发现表明抗白背飞虱基因在中国存在于同一生态区的粳稻地方品种中。

Abstract: Ovicidal- and sucking-inhibitory resistance to the whitebacked planthopper (WBPH) in 13 japonica, 11 indica, 13 hybrid rice from China, and 11 tropical japonica from other countries were evaluated. Ovicidal varieties were found only in japonica rice, four of 13 japonica varieties showed significant ovicidal response. No ovicidal varieties were involved in indica, hybrid and tropical japonica varieties tested. In addition, 42 japonica and 43 indica varieties from different provinces in China were re-evaluated for WBPH resistance. Ten japonica varieties (about 24%) had ovicidal resistance, causing 53%-100% egg mortality. In more than 95% of indica varieties, WBPH egg mortality was below 30%. Only four japonica varieties from Zhejiang Province significantly suppressed honeydew excretion by WBPH. Among 21 japonica landraces in Zhejiang Province, ovicidal and sucking response of WBPH showed independent and continuous variations. Sanqianhuang, Changhongdao and Aigandao had ovicidal resistance. Jijiaohuang and Maqueqing inhibited WBPH sucking. This finding indicated that WBPH resistance genes were retained in sympatric japonica landraces in China.
