番茄是设施栽培重要的果类蔬菜。近年番茄黄化曲叶病毒、褪绿病毒和灰叶斑病的爆发，对番茄生产造成巨大影响，选育抗病性好的番茄品种成为关键。目前国内外对黄化曲叶病毒的研究已取得较大进展，但对于褪绿病毒和灰叶斑病的研究还未取得有效成绩，选育黄化曲叶病毒、褪绿病毒和灰叶斑病多抗的品种成为必然。番茄的消费量近年不断增加，进口品种一般单果重160-180克，属于中小果型，果型美观，硬度好，商品性可，但产量低，经济效益不高；国产品种一般单果重200-300克，属于大果型，果型美观，品质好，产量高，但果实软，硬度差，耐储运性差，商品性差，经济效益不高。当前番茄品种向大果型，单果重250克以上，口感好，耐储运，货架期达到15天以上，果实硬度高的方面发展。

Tomato is an important fruit vegetable in protected cultivation. In recent years, the outbreak of Tomato yellow leaf curl virus, chlorosis virus and gray leaf spot disease has a huge impact on tomato production, and the key is to select tomato varieties with good disease resistance. At present, great progress has been made in the research of yellow leaf curl virus at home and abroad, but no effective achievements have been made in the research of chlorosis virus and gray leaf spot disease, so it is necessary to select varieties with multiple resistance to yellow leaf curl virus, chlorosis virus and gray leaf spot disease. The consumption of tomato has been increasing in recent years. The average weight of imported single fruit is 160-180g, which belongs to the small and medium fruit type. The fruit type is beautiful, hard and marketable, but the output is low, and the economic benefit is not high. The average weight of domestic single fruit is 200-300g, which belongs to the large fruit type. The fruit type is beautiful, the quality is good, the output is high, but the fruit is soft, the hardness is poor, the storage and transportation resistance is poor, the commodity is poor, and the economic benefit is poor Not high. At present, tomato varieties are developing into large fruit type, with a single fruit weight of more than 250g, good taste, storage and transportation resistance, shelf life of more than 15 days, and high fruit hardness.<br>
