摘　　要：采用田间病圃自然鉴定方法,对12个花生品种进行抗病性研究。结果表明:对花生叶斑病、网斑病和根腐病表现出高抗的品种各1个,分别为豫花9326(相对抗病指数87.39%)、豫花15号(82.71%)和豫花21号(92.10%)。品种之间抗病性差异很大,综合抗病性以豫花9326、豫花15号、豫花21号最佳,豫花9805、商研9658较好,濮花9519、开农49、开农61次之,其他品种较差。商研9807、豫花21号、商研9658、开农61、豫花9805的荚果产量分别比对照(豫花15号)增产19.37%、15.81%、11.87%、10.27%、9.66%,增产效果显著,可作为花生生产的主导品种进行推广应用。The disease resistance of 12 peanut varieties was studied via field identification.The results showed that the highly resistant varieties against peanut leaf spot,peanut web blotch disease and peanut root rot were Yuhua 9326（relative disease resistance index of 87.39%）,Yuhua 15（82.71%） and Yuhua 21（92.10%） respectively.The disease resistance between these varieties differed significantly.Integrated resistance to Yuhua 9326,Yuhua 15,Yuhua 21 were the best,Yuhua 9805,Shangyan 9658 were better,followed by Puhua 9595,Kainong 49,Kainong 61,and the other varieties were poor.The peanut yields of Shangyan 9807,Yuhua 21,Shangyan 9658,Kainong 61,and Yuhua 9805 were significantly higher than the control variety（Yuhua 15）,with yield increasing percentages（relative to the control variety） of 19.37%,15.81%,11.87%,10.27%,and 9.66%,respectively.We recommended these five varieties as the leading varieties in peanut cultivated areas in eastern Henan plain.
