Abstract Grafting analysis was carried out using three tomato(Lycopersicon esculentum Mill.)lines introduced from Tomato Genetics Resource Center USA(TGRC):LA2701,LA3202 and LA3526 with high resistance to bacterial wilt as rootstocks and‘Zaoguan 30’as cions.Grafted plants were inoculated with Ralstonia solanacearum and bacterial wilt resistance was investigated.Results indicated that the three tomato lines could improve the bacterial wilt resistance obviously.Ralstonia solanacearum in vivo analysis indicated the grafting with bacterial wilt resistant rootstocks could effectively inhibit the propagation of bacterial cells in tomato stem.
