摘　　要：该文对引自8个省份的72个核桃资源的果实抗病性进行了连续3a的田间调查。结果表明:不同核桃资源果实抗病性差异较大,张秀峰北、燕香、金薄香4号、西洛7号、硕宝、鲁核5号、卢龙白水、史文海8个品种(系)病果率在5%以下,为高抗资源,占到了调查品种(系)的11.1%,病果率在60%以上的易感病资源有23个,占到了调查品种(系)的31.9%。结果还表明:单纯从引进的资源来看,不同区域的资源抗病性也不同,引自辽宁的品种抗病性较强。In this paper,the fruit disease resistance of 72 walnut resources introduced from 8 provinces was investigated for 3 years.The results showed that:the fruit disease resistance of different walnut varieties varied greatly.The diseased fruit rates of‘Zhangxiufengbei’,‘Yanxiang’,‘Jinboxiang NO.4’,‘Xiluo NO.7’,‘Shuobao’,‘Luhe NO.5’,‘Lulongbaishui’and‘Shiwenhai’were below 8%,which were highly resistant resources accounting for 11.1%of the investigated varieties(species).there were 23 susceptible resources,accounting for 31.9%of the investigated varieties(species),the diseased fruit rates of which were higher than 60%.In addition,the fruit disease resistance of introduced resources showed regional difference,the varieties introduced from Liaoning Province had higher disease resistance.
