摘要
利用群体抗性标准,对课题组选育的52份南瓜自交系材料进行病毒病的田间发病情况调查分析。结果表明:不同南瓜自交系对病毒病的抗病性存在明显差异,未发现病毒病免疫和高抗类型材料;抗病类型材料4份,为甜面瓜、112-2、042-1、360-3,占供试材料总数的7.69%;中抗类型材料22份,占供试材料总数的42.31%;感病26个,占供试材料总数的50%。
Field investigation and analysis on virus disease of 52 inbred lines of pumpkin selected by the research team were done with standard of group resistance.The results showed that resistance of different inbred lines of pumpkin varies remarkably.Material with virus immunity and high resistance was not found;four resistant material were found,including Sweet Miangua,112-2,042-1,360-3,accounting for 7.69% of the total material;twenty-two moderate resistance material were indentified,taking 42.31% of the whole and twenty-six susceptible material were found,covering 50% of the total material.
