摘　　要：为筛选抗疮痂病花生品种资源,采用喷雾法对60个花生品种进行抗病性鉴定,结果表明:供试的省外引进品种中,两年鉴定表现抗病(R)的有6个品种,占参试品种的14.29%;中抗(MR)的有14个品种,占33.33%;中感(MS)的有18个品种,占42.86%,感病(S)的有4个品种,占9.52%;供试的18个福建省审(认)定品种,抗疮痂病性差,表现中感的有2个品种,其余品种均为感病。近年来,花生疮痂病危害趋重,今后在花生新品种选育中,有必要将抗疮痂病作为花生品种改良的一个重要目标。In order to screen and explore peanut germplasm resources resistant to scab disease, the disease-resisting capacity of 60 peanut varieties were identified by spraying method. The results showed that, among the introduced varieties from other provinces, 6 varieties were proved to be resistant, accounting for 14.29% ; 14 varieties were moderately resistant, accounting for 33.33% ; 18 varieties were moderately susceptible, accounting for 42.86% ; 4 varieties were susceptible, accounting for 9.52%. 18 peanut varieties from Fujian province showed low resistance to scab, 2 of which were moderately susceptible, the rest were susceptible. The results of this study provided important references for the breeding of peanut varieties with resist- ance to scab. In recent years, peanut scab disease tend to be more serious, so it is necessary to chose the scab - resistant ca- pacity as an important target in the peanut variety improvement.
