首发时间:2023-03-06
摘要:为提高马铃薯晚疫病抗病育种水平,确定不同马铃薯品种对晚疫病的抗性水平,对引自全国的35份马铃薯品种(系)进行晚疫病田间抗性评价。鉴定结果表明:在供试马铃薯资源材料中,高抗品种占比31.25%,中抗品种占比12.50%,中感品种占比40.625%,感病品种占比15.625,其中,"云薯108"等10个品种对马铃薯晚疫病表现好于对照抗病品种"鄂马铃薯14",表现出高抗,可作为马铃薯晚疫病抗病育种的资源。

Evaluation of Potato Cultivars with Late Blight Resistance in Enshi
Abstract:In order to improve the breeding level of potato late blight disease resistance and determine the resistance level of different potato varieties to late blight disease, evaluation of 35 Potato Cultivars were carried out. The identification results showed that among the tested potato resource materials, high resistance varieties accounted for 31.25%, medium resistance varieties accounted for 12.50%, medium susceptible varieties accounted for 40.625%, and susceptible varieties accounted for 15.625. Among them, 10 varieties, such as "Yunshu 108", showed higher resistance than the control resistant variety "E malingshu 14",and they can be used as the breeding resource for potato late blight disease resistance.
