中文摘要:由番茄黄化曲叶病毒(ToLCV)引起的番茄黄化曲叶病对全球番茄生产产生了严重的限制。2014-2015年秋季,利用10个亲本和45个F-1杂交种对ToLCV和4个园艺特征进行了抗性评估。在诱导的自然疾病和粉虱介导接种条件下对抗ToLCV品种进行了筛选,症状范围从无症状到非常严重的感染。基于对抗ToLCV性的品种及4个园艺性状的筛选,本文鉴定了4个有利于商业用途的番茄杂交种,即CLN 138AxCLN 138B、CLN 138BxPVB-1、CLN 104xCLN 154和CLN 17xPVB-1。这些杂交种在经受粉虱介体接种病毒后表现出了抗性,产量提高了40%,并且与自然疾病条件下的商业对照相比,果实重量、TSS和番茄红素含量优于或与其相当。
外文摘要:The leaf curl disease of tomato (Solanum lycopersicum L.) caused by tomato leaf curl virus (ToLCV) poses a serious production constraint throughout the world. An evaluation for resistance to ToLCV and four horticultural traits was carried out using 10 parents and 45 F-1 hybrids during the autumn of 2014-2015. Screening against ToLCV was done under both induced natural disease conditions and whitefly (Bemisia tabaci Genn.)-mediated inoculation, with symptoms ranging from symptomless to very severe infection. Under the natural disease conditions, seven parents and 20 F-1 hybrids appeared symptomless until the fruit maturation stage. Using the artificial inoculation technique, six parents and 18 hybrids showed resistance at 60days post inoculation. The correlation coefficients indicated that breeding for ToLCV-resistant hybrids enhanced total yield, fruit weight and total soluble solids content of fruits under natural disease conditions. Based on screening for resistance to ToLCV and four horticultural traits, we identified 4 tomato hybrids, namely CLN 138AxCLN 138B, CLN 138BxPVB-1, CLN 104xCLN 154 and CLN 17xPVB-1 to be favorable for commercial use. These hybrids showed resistance after undergoing the whitefly-mediated inoculation, produced 40% higher yield, and were either superior or at par for fruit weight, TSS and lycopene content when compared to the commercial control under natural disease conditions.
