| 摘 要： | 在明确甜瓜白粉病生理小种的基础上,对从国内外搜集的109份甜瓜种质材料进行苗期接种鉴定。子叶展平后,采用孢子悬浮液法接种S.fuliginea属的2F小种,接种12～15d充分发病后开始调查抗感反应。鉴定结果显示,供试甜瓜种质中,高抗材料19份,中抗材料37份,中感材料33份,感病材料20份。抗病材料中有6份美国的厚皮甜瓜,1份法国厚皮甜瓜,2份日本厚皮甜瓜,2份中国薄皮甜瓜。研究将为改良甜瓜白粉病抗性和甜瓜抗病育种提供有潜在利用价值的基因资源和基本技术支持。 |

| Abstract: | Total 109 materials both at home and abroad were evaluated for resistance to S.fuliginea race 2F by inoculating spore suspension in seedling stage.The results showed that 19 materials showed high resistance to S.fuliginea race 2F;37 materials showed middle resistance;33 materials showed middle susceptible;20 materials showed highly susceptible].In resistant materials,six thick-skinned materials from the USA,one thick-skinned material from France,two thick-skinned materials from Japan,and two thin-skinned materials from China were included.This study indicated that resources had resistant genes which had a potential value to melon powdery mildew resistance improvement and resistance breeding. |
