作物抗性是一种具有成本效益和环境友好的害虫管理策略。褐飞虱（Nilaparvata lugens）是一种严重危害水稻的害虫，它能迅速克服植物的抗性，但又缺乏足够的抗性资源。BR4831（将两个抗褐飞虱基因Bph 14和Bph 15分别导入优良品种黄花占（HHZ）的水稻育种系）和两个单基因渐渗系（HF 106，携带Bph 14，和C602，携带Bph 15，采用标准种箱筛选试验和田间试验相结合的方法，对9311号品种的抗褐飞虱性进行了评价。利用实验室测定确定相关抗性类型。种子箱试验和室内生物测定结果表明，BR 4831表现出较强的抗生素抗性，行为测定结果表明，该品系也表现出较强的抗异源性，而HF 106和C602表现出较弱的抗性，不表现抗异源性。田间试验结果表明，BR 4831的抗病性比受体亲本HHZ显著提高，HF 106和C602的抗病性比受体亲本9311略有提高。这些结果表明，水稻品系BR4831，具有抗蚜基因，表现出比单基因系HF106和C602更高的抗性，并强调了种子箱育苗试验，田间试验和室内测定相结合，以彻底分析植物抗性类型的好处。
Crop resistance is a cost-effective and environmentally friendly strategy for pest management. The brown planthopper (BPH, Nilaparvata lugens) is a devastating rice insect pest due to its ability to rapidly overcome plant resistance and the lack of sufficient resistance resources. BR4831 (a rice breeding line derived from the pyramiding of two BPH resistance genes, Bph14 and Bph15, into the elite rice variety Huang-Hua-Zhan, HHZ) and two single-gene introgression lines (HF106, carrying Bph14, and C602, carrying Bph15, in the elite rice cultivar 9311) were evaluated for their resistance to BPH using a standard seed box screening test coupled with field tests. The related resistance types were determined using laboratory assays. The seed box test and laboratory biological assays showed that BR4831 exhibited strong antibiotic resistance, and the behavioral assay showed that this line also exhibited strong antixenotic resistance, while both HF106 and C602 exhibited only weak antibiosis and no antixenotic resistance. Field tests showed significantly improved resistance in BR4831 compared to that of its recipient parent HHZ and slightly increased resistance in HF106 and C602 in comparison with their recipient parent 9311. These results demonstrate that the rice line BR4831, with pyramided resistance genes, exhibits higher resistance than the monogenic lines HF106 and C602 and highlight the benefits of combining the seed box seedling test, field tests and laboratory assays to thoroughly analyze plant resistance types.
