花生品种资源抗疮痂病鉴定研究初报

    Preliminary report on identification of peanut germplasm resources resistant to scab disease

    • 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。

       

      Abstract: 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 resistance to scab. In recent years, peanut scab disease tend to be more serious, so it is necessary to chose the scab-resistant capacity as an important target in the peanut variety improvement.
