| 摘 要： | 对梨属(Pyrus Linn)5个种368份资源通过抗梨黑斑病的田间自然鉴定和初选出的35份综合性状优良的抗性资源进行人工接种鉴定,结果表明:杜梨(P.betulaefolia Bge.)的抗性最强,西洋梨(P.communis L.)的抗性最弱;不同品种对黑斑病的抗性差异很大。砂梨按照地方品种群划分,其抗性由强到弱的排序为广东梨、福建梨、湖南梨、广西梨、浙江梨、贵州梨、四川梨、云南梨、湖北梨、日本梨、江西梨。筛选出8份抗性资源,1份高抗资源。

| Abstract: | The resistance to black spot disease of 368 pear genetic resources, including 5 species of Pyrus Linn, were studied in the field conditions in the national sand-pear repository at Wuhan, Hubei province,35 accessions were evaluated by anificial inoculation. The results showed that the P. betulaefolia Bge was the strongest one and P. communis L weakest one. Resistant indexes( % ) of district clones of sandpear were:Guangdong pear 10.42,Fujian pear 12.5,KHunan pear 18.33,Guangxi pear 21.53,Zhejiang pear 21.82,Guizhou pear 27.50,Sichuan pear 23.68, Yunnan pear 23.81, Hubei pear 24.53, Japanese pear 25.00 and Jiangxi pear 27.50.1 high resistant and 8 resistant varieties or clones were identified by artificial inoculation. |
