| 摘 要： | 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。

| Abstract: | 6 varieties resisting to WBPH were obtained.Genetical analysis of resistance showed a single dominant gene governs the resistance in the varieties individually and the gene for HA79317-7 is allelic to Wbph 1,and for Dianri 336-3 to Wbph 2; and the genes for Guiyigu,Dahuagu,Daqigu and Biangu are nonallelic to Wbph 1 and Wbph 2. |
