摘要
为丰富青海地区抗褐斑病的樱桃种质资源,本研究以山东果树研究所及山东泰安华夏农林发展有限公司的樱桃品种(系)作为试验材料,采用室内离体叶片接种法,分别用链格孢(A.alternata)和极细链格孢(A.tenuissima)侵染95份和80份品种(系),通过方差分析和聚类分析评价其抗病性。结果表明:在链格孢(A.alternata)侵染下,鲁樱1号、鲁樱2号、鲁樱3号、鲁樱5号、鲁樱7号、鲁樱8号、金蜜脆、俄罗斯8号、大紫、12-4、12-9、16-4、巨红、鲁樱9号、鲁樱6号、泰奥佳等品种表现出抗病性;在极细链格孢(A.tenuissima)侵染下,齐早、俄罗斯8号、大紫、16-4等品种表现出抗病性。本研究为青海引种抗褐斑病樱桃品种提供了科学依据。
In order to enrich the Prunus spp.germplasm resources resistant to brown spot disease in Qinghai,this study used Prunus spp.varieties(lines)from Shandong Fruit Research Institute and Shandong Tai'an Huaxia Agriculture and Forestry Development Co.Ltd.as experimental materials.Using detached leaf inoculation method,95 and 80 varieties(lines)were infected with A.alternata and A.tenuissima respectively.Disease resistance was evaluated through variance analysis and cluster analysis.The results are as follows:Under the infection of A.alternata,the varieties such as Luying 1,Luying 2,Luying 3,Luying 5,Luying 7,Luying 8,Jinmicui,Russian 8,Dazi,12-4,12-9,16-4,Juhong,Luying 9,Luying 6 and Taiaoja showed disease resistance.Under the infection of A.tenuissima,the varieties such as Qizao,Russian 8,Dazi and 16-4 showed disease resistance.The research results can provide scientific basis for introducing Prunus spp.varieties resistant to brown spot disease in Qinghai.
