摘　　要：为筛选流胶病抗性较强的桃/油桃栽培品种和种质资源,以110个桃/油桃地方品种和选育品种为试验材料,调查4—7年生树的流胶病田间发病情况,并结合系谱分析,追溯流胶病抗性种质来源。结果显示,不同桃/油桃品种间流胶病等级差异明显,抗性随树龄增大而逐渐下降,80个品种的流胶病等级表现较稳定,其中:9个品种表现为高抗,多为桃品种,代表品种有‘秋白桃’‘南山甜桃’等;40个品种表现为抗病,代表品种有‘白丽’‘圆梦’等;16个品种表现为中抗,代表品种有‘湖景蜜露’‘锦绣’等;9个品种表现为感病,代表品种有‘肥城白里’‘仓方早生’等;6个品种表现为高感,代表品种有‘白露桃’‘沪油278’等。桃品种的抗病性总体优于油桃品种。根据品种遗传系谱分析发现,部分抗病及高抗品种间存在不同程度的亲缘关系,‘上海水蜜’是部分抗病及高抗品种的原始亲本。本研究结果可为生产上选择合适的抗病品种和后续的抗病遗传育种提供参考。This study aimed to screen highly resistant varieties by investigating field gummosis disease levels in 110 local peach/nectarine varieties and selected varieties of 4-to 7-year-old trees.Combined with pedigree analysis,the source of the gummosis disease resistant germplasms was traced.The results showed that there were significant differences in the levels of gummosis disease among different peach/nectarine varieties,and the resistance gradually decreased with the increase of tree age.Among the 80 varieties that showed relatively stable levels of gummosis disease,nine varieties showed high resistance,most of which were peach varieties,such as‘Qiubaitao’and‘Nanshantiantao’;40 varieties showed resistance,such as‘Hakuri’and‘Yuanmeng’;16 varieties showed moderate resistance,such as‘Hujingmilu’and‘Jinxiu’;nine varieties were susceptible to the disease,such as‘Feicheng Baili’and‘Kurakato Wase’;and six varieties showed high susceptibility,such as‘Bailutao’and‘Huyou 278’.The peach varieties were generally more resistant than the nectarine varieties.According to the genetic pedigrees,some resistant and highly resistant varieties,which originated from the traditional Chinese local variety‘Chinese Cling’,had a genetic relationship.This research provides a reference for the selection of resistant varieties in production,as well as for further genetic and breeding applications.
