通过抗性鉴定,筛选出6个抗白背飞虱的国内品种:鬼衣谷、大花谷、大齐谷、便谷、滇瑞336.3和HA 79317-7(前4个品种均系云南地方品种)。遗传分析证明,这6个品种对白背飞虱的抗性均受单显性基因控制。HA 79317-7的抗性基因与Wbph1等位,滇瑞336-3的抗性基因与Wbph2等位。鬼衣谷、大齐谷、大花谷和便谷的抗性基因均与Wbph1、Wbph2非等位。它们与Wbph3、Wbph5的等位关系还有待进一步研究。 Through resistance identification, six domestic varieties of whitebacked planthopper, Sogatella furcifera were screened: Guiyi Valley, Huacha Valley, Datong Valley, Baotang, Dianrui 336.3 and HA 79317-7 (the first four varieties were all Yunnan local cultivars ). Genetic analysis showed that the resistance of these six cultivars to whitebacked planthopper was controlled by a single dominant gene. The resistance gene of HA 79317-7 is at the Wbph1 allele and the resistance gene of Dianrei 336-3 is at the Wbph2 allele. The Ghost Valley, Big Valley, Large Flower Valley and Bowie resistance genes and Wbph1, Wbph2 non-allelic. Their relationship with Wbph3, Wbph5 remains to be further studied.
