1 育种目标

番茄(Solanum lycopersicum L.)是世界上栽培和消费最广泛的蔬菜作物之一,我国已成为全球最大的番茄种植、生产和消费国。因其营养丰富、丰产高效,深受广大消费者和生产者欢迎,番茄含有丰富的矿物质、维生素和番茄红素,其番茄红素具有延年益寿、防癌抗癌的功效[1],因此,在农业增产、农民增收以及在农业产业结构调整中起重要的作用。科学研究的目的是解决生产上的主要问题,番茄育种的方向也是为生产服务,丰产、抗病、优质是番茄育种的主要目标,在品质育种方面,更多集中在颜色、大小、形状等商品外观等方面,尽管在育种中兼顾品质,但要求较低,育成的品种口感较差。近几年,随着粉虱传播的病毒病的发生与流行,我国番茄产业面临着巨大的挑战,尤其是番茄黄化曲叶病毒病的暴发,给番茄产业带来巨大的损失[2-5],抗番茄黄化曲叶病毒(Tomato yellow leaf curl virus,TYLCV)成为首要的育种目标。随着社会的发展和人们生活水平的提……
