摘要
近年来,广西番茄黄化曲叶病毒病(TYLCD)发生较为严重,病原也比较复杂(发现4种病毒且存在复合侵染现象),对广西的番茄生产造成了很大威胁,种植抗病品种是防治该病的关键措施。本研究对中国农科院蔬菜花卉所、上海市农科院园艺所、浙江省农科院蔬菜所、江苏省农科院蔬菜所、北京市农林科学院蔬菜研究中心和广西大学提供的43份抗TYLCD番茄品种在广西南宁的自然抗病性进行了评价。采用自然诱发的方法,病圃的番茄混合感染中国番茄曲叶病毒与中国番木瓜曲叶病毒。试验结果表明,表现高抗的品种有‘浙红3号’、‘浙红4号’、‘K22’、‘K64’等8个番茄品种,表现抗病和中抗的品种有‘红贝贝’、‘春展56’等25个品种,表现感病的品种有‘樱红1号’、‘K6’等5个品种,表现高感的品种有‘金陵佳玉’、‘苏粉11号’等5个品种。本试验结果为抗病番茄品种在广西乃至全国的推广和布局提供参考。
Tomato yellow leaf curl disease（TYLCD）occurred seriously and cause severe economic losses in Guangxi during recent years.Application of resistant variety was the best way to control this disease.In this study,the natural resistances of 43 TYLCD-resistant tomato varieties collected from Chinese Academy of Agricultural Sciences,Shanghai Academy of Agricultural Sciences,Zhejiang Academy of Agricultural Sciences,Beijing Academy of Agricultural Sciences,Beijing Academy of Agriculture and Forestry Sciences and Guangxi University were determined by the methods of Bemisia tabaci inoculation naturally in Nanning City,Guangxi Zhuang Autonomous Region.The diseased tomato were mix-infected by Tomato leaf curl China virus（ToLCCNV）and Papaya leaf curl China virus（PaLCuCNV）in diseased nursery.The result showed that 8 varieties（including‘Zhehong 3＇,‘Zhehong 4＇,‘K22＇,‘K64＇etc.）were highly resistant to TYLCD;25 varieties were resistant and moderately resistant,5 varieties were susceptible,and 5 varieties were highly susceptible.The results could provide a theoretical reference for the extension of these TYLCD-resistant tomato varieties in Guangxi and other regions of China.
