Abstract：In order to better understand the resistance of major tomato（Solanum lycopersicum）cultivars in Baiyin City of Gansu Province and the introduced varieties for Meloidogyne incognita，their resistance were identified by indoor and field experiments．The results showed that there were no immune cultivars in tested cultivars，among them ‘Xianke No.1’，'Xianke No.6’，'Diweisi’ and ‘Jinpeng M6099’ were highly resistant in indoor seedling stage and field adult stage，'Jinpeng M18’ was susceptible. The resistance of 'Xianke No.8’ and ‘Jinpeng M701’ were stronger at seedling stage than adult stage，while the resistance of 'Jinpeng M5038’，'Di′ao’and 'Jiahong No.6’ were stronger at adult stage than seedling stage. The high yield and resistance of tested varieties 'Jinpeng M5038’，'Jinpeng M6099’ and ‘Diweisi’ were all good.
