N2 - Tree tomato is a crop of Andean origin. This is cultivated mainly in South America and it is increasingly in demand worldwide. However, it is a crop very susceptible to pests and diseases. There are currently improvement programs to obtain resistant cultivars that include wild species for introgression of features of interest such as disease resistance and improvement of fruit quality in commercial plantations. However, although some segregators of the crosses made have shown resistance in field conditions, the information available regarding molecular markers useful in the interactions of this crop with its main pathogens is scarce. In Ecuador, the main pathogens that attack tree tomatoes are Colletotrichum sp., Meloidogyne sp. and virus species classified in six genera: Potyvirus, Cucumovirus, Tospovirus, Tobamovirus, Potexvirus and Polerovirus. The presence of these pathogens has been detected with the use of different molecular techniques. This report presents the current status in the use of molecule markers, both in the diagnosis of diseases, and in the detection of resistance-related information.
