对参试的218份花生种质进行疮痂病抗性人工接种和自然病圃鉴定,结果表明,对疮痂病反应为感病的种质有矮三棵、印度红、发财生和铁板青等16份,包括目前生产上的主栽品种粤油116、泉花10号、汕油523和粤油551等。反应为中感的种质有汕油71、白沙1016、金花1012和鲁花12号等26份。反应为中抗的种质有豫花15号、花育17、淮花8号和粤油9号等61份。表现为抗病的种质有P903-2-40、ICG 1376,干引选1001和美引选41082等20份。对该病反应为中抗以上水平的种质,皆可作为杂交抗病亲本利用,显示出花生种质对疮痂菌侵染反应中蕴藏着丰富的抗源基因。
218 peanut germplasms were tested for artificial resistance to scab-resistant inoculation and identification of natural nurseries. The results showed that the germplasms susceptible to the scab disease were Achillea indica, Indian red, Caragana spp. 16, including the current production of the main cultivars Yueyou 116, Quanhua 10, Shanyou 523 and Guangdong Oil 551 and so on. The germplasm of the response was Shanyou 71, Baisha 1016, Jinhua 1012 and Luhua 12. The germplasm that responded to Zhongkang was Yuhua 15, Huayu 17, Huaihua 8 and Yueyou 9. Performance of disease-resistant germplasm P903-2-40, ICG 1376, dry quoted 1001 and the United States cited 41082 and other 20 copies. The response to the disease is above the level of anti-resistance germplasm, can be used as cross-resistant parents, shows that peanut germplasm infection in the pathogen contains rich resistance gene.
