| 摘 要： | 采集田间自然发病甜瓜白粉病病原菌孢子,利用孢子悬浮液喷雾法对海南常种植的甜瓜品种对白粉病抗性进行了初步鉴定。结果表明,7个品种中有金蜜六和金辉一号2个为中度抗病,其余均为高度抗病。接种后14d,发病率最低的是新红心脆,为68.8%;病情指数最低的是金蜜十,为13.95。

| Abstract: | Powdery mildew pathogen spores of melon were collected under nature infection in field.The resistance of seven cultivars of melon in Hainan province was preliminary identified with the spore suspension.The results showed thatJinmi No.6 and Jinhui No.1 were indicative of middle disease-resistance,the other were indicative of high disease-resistance.The incidence of Xinhongxincui was 68.8% which was the lowest,the average of disease index of Jinmi No.6 was13.95 which was the lowest of seven cultivars. |
