通过2010年对江苏稻区推广面积较大的5个品种粳稻上稻飞虱的发生量及对产量影响进行研究发现,宁粳1号、淮稻9号最耐白背飞虱,南粳44次之,扬粳9538、武运粳23耐虫性较差;以宁粳1号、淮稻9号最耐褐飞虱,武运粳23、扬粳9538次之,南粳44最不耐。后期褐飞虱对产量影响较大,在5个试验的品种中,以对淮稻9号和南粳44产量的影响最大,其次是扬粳9538、武运粳23,而对宁粳1号的影响最小。与产量最低的淮稻9号相比,南粳44、扬粳9538、武运粳23、宁粳1号的产量分别高出2.88%、20.45%、24.07%、45.50%。
Through the research on the occurrence and yield of rice planthoppers on 5 rice cultivars with larger area in Jiangsu Province in 2010, Ningjing 1 and Huai 9 are the most resistant to whitebacked planthopper, Nanjing 44 Secondly, Yangjing 9538 and Wuyunjing 23 had less tolerance to insects. Ningjing 1 and Huai 9 were the most resistant to brown planthopper, Wuyunjing 23 and Yangjing 9538, while Nanjing 44 was the most impatient. The late BPH had a great influence on the yield. Among the five tested cultivars, the effect was greatest on the yield of Huai 9 and Nanjing 44, followed by Yangjing 9538 and Wuyunjing 23 and the effect on Ningjing 1 Min. The yield of Nanjing 44, Yangjing 9538, Wuyunjing 23 and Ningjing 1 were 2.88%, 20.45%, 24.07% and 45.50% higher than that of Huai 9 at the lowest yield respectively.
