摘要:

褐飞虱是危害水稻的一种重要害虫。为探究聚合Bph14Bph15基因材料及其不同组合对褐飞虱的抗性变化情况以及机制,本研究选取 10 份水稻材料,分别开展苗期和成株期抗虫鉴定工作,测试了这 10 份水稻材料对褐飞虱的抗生性、趋避性以及耐害性。研究结果显示,携带Bph14Bph15基因材料及其不同组合在苗期和成株期对褐飞虱均表现出抗(R)或高抗(HR)水平,且同时具备对褐飞虱的抗生性、趋避性以及一定的耐害性。本研究所获得的抗虫材料可将为抗褐飞虱杂交稻新品种的配组提供优异的种质亲本。

Abstract:

The brown planthopper (Nilaparvata lugens) is a significant pest that causes severe damage to rice. To investigate the changes in resistance and the resistance mechanism against the brown planthopper of rice materials with pyramided Bph14 and Bph15 genes, as well as their different combinations, this study selected 10 rice materials. Antifeedant identification was conducted at both the seedling and adult stages, and tests were carried out to assess the antibiosis, antixenosis, and tolerance of these 10 rice materials against the brown planthopper. The results revealed that rice materials carrying the Bph14 and Bph15 genes, along with their different combinations, exhibited resistance (R) or high resistance (HR) levels to the brown planthopper at both the seedling and adult stages. Moreover, they simultaneously demonstrated antibiosis, antixenosis, and a certain degree of tolerance against the pest. The insect-resistant materials obtained in this study will serve as high-quality germplasm parents for the breeding of new hybrid rice varieties resistant to the brown planthopper.

Key words: rice, brown planthopper, antibiosis, antixenosis, tolerance
