摘要:

为明确山东省主栽花生品种对疮痂病的抗性及疮痂病对花生产量的影响,2018-2019年在山东省莱西市对36个主栽品种进行了抗疮痂病鉴定,鉴定通过人工接种分别在田间和温室大棚内进行,并分析了病害对产量影响。结果表明,供试品种有高感品种8份,占鉴定品种总数的22.22%;感病品种4份,占鉴定品种总数的11.11%;中抗品种2份,占鉴定品种总数的5.56%;抗病品种11份,占鉴定品种总数的30.56%;高抗品种11份,占鉴定品种总数的30.56%。花生疮痂病病情与产量损失率呈指数关系,病情指数越高,花生产量损失率越大。

Abstract:

In order to detect the different disease resistance of peanut main varieties in Shandong to peanut scab (Sphaceloma arachidis Bitaucourt et Jenkins) and its effect on peanut yield, in 2018-2019, we evaluated 36 peanut germplasm resources for resistance to peanut scab. The evaluation wascarried out in the field and greenhouserespectively,we also analyzed the effect of disease onyield. The result showed that there were 8 accessions as high susceptibility (HS) accounted for 22.22%; 4 accessions rated as susceptibility (S) and accounted for 11.11%; 2 accessions rated as moderate resistant (MR) and accounted for 5.56%; 11 accessions rated as resistant (R) and accounted for 30.56%; 11 accessions rated as high resistant (HR) and accounted for 30.56%.There was an exponent relation between the disease index and yield loss rate, the yield loss rate increased with the increase of decrease index.

Key words: peanut, Sphaceloma arachidis, evaluation of resistance, yield loss rate
