Abstract: 【Objective】 As an important vegetable crop, tomato is a model plantform genetic research. The development of sequencing technology will lay a solid foundation for the excavation of important functional genes in tomato.【Method】 High quality of tomato genome information by analyzing and comparing the relative websites、researches and technologies will provide a reliable research strategy for breeders. 【Result】The development of sequencing technology has greatly promoted tomato genome research. It took eight years for sequencing and assembling the genome of cultivated tomato S. lycopersicum Heinz 1706 by first and second generation of sequencing technology. However, three wild tomato species was sequenced by second generation of sequencing technology only within three years. Comparing with the second generation of sequencing technology, the third generation of sequencing technology not only shorten the sequencing time, but also improved the genome quality by providing wild tomato S. pennellii genome sequence with higher integrity of 96.46%.【Conclusion】From the comparison of genome sequencing technology, we gained the conclusion that the third generation of sequencing technology has greatly improved the sequencing speed, the reading length and the accuracy of the genome sequencing. At the same time, it makes the genome assembly more accurate. The decoding of tomato genome information will open a new way for tomato researchers gained new varieties of tomato.
