Abstract
Bacterial wilt is a disease that is of global importance because it is difficult to control and often compromises the whole crop. The use of resistant varieties is the main form of control of this disease. The objective of this work was to carry out a literature review with the main factors related to the botany and breeding of tomato to obtain genotypes resistant to bacterial wilt. It was found different information related to the genetic control of tomato resistance in relation to the number of genes and their interaction due to the high genetic diversity within the Ralstonia solanacearum species complex, which is the cause of bacterial wilt. The high host-pathogen interaction reflects on different breeding strategies depending on the environment and the source of resistance used.
