| 摘 要： | 1983—1990年在抗病系比苗圃和大田鉴定了48个主要橡胶品系对白粉病的抗性。结果表明:RRIC52、红山67—15等品系具有高度抗病力;热研11—9、RRIC102、IAN873;湛试8—67—3等品系,具有中度抗病力,热研14—20、八—36—3、保亭938、热研7—33—97、文昌12—12、RRIC100、RRIM600等品系,也具有中度抗病力,但个别年份易发病,属于中抗至中度感病品系;其他品系都不同程变地感病,其中PB5/51、热研88—13、PR107、热研44—9等品系尤其感病。

| Abstract: | The resistance of popular rubber clones in China to Oidium heveae were tested in nursery and fields during 1983-1990. Testing results showed that clones RRIC52, Hongshan 67-15 posscssd high resistance to Oidium heveae. SCATC11-9, RRIC102, Zhanshi 8-67-3 had moderate resistance. Clones SCATC 14-20, Bayi36-3, Baoting936, SCATC7-33-97, Wenchang 12-12, RRIC100, RRIM600, although also had moderate resistance, their disease severity being higher in some years, they belonged to moderate resistance or moderate susceptibility. The other clones tested were susceptible to the disease, cspecially PB5/51, SCATC88-13, PR107, SCATC 44-9. |
