Estado actual del uso de marcadores moleculares en el diagnóstico y control genético de enfermedades de naranjilla

Abstract

Naranjilla or lulo (Solanum quitoense) is an important native fruit crop to northwestern South America. It is planted mainly in Colombia and Ecuador and is increasingly in demand worldwide. However, it is very susceptible to attack by pests and diseases. In Ecuador, the main pathogens that attack naranjilla are Fusarium oxysporum and Meloidogyne incognita. In addition, a virus of the Tymoviridae family has been detected, which was called Naranjilla chlorotic mosaic virus (NarCMV) and a viru that causes mosaic that has been called Naranjilla mild mosaic virus (NarMMV). Presence of these pathogens has been detected in using different molecular techniques. This report presents the current status in the use of molecular markers, both in diagnosis of diseases and in detection of information related to resistance in naranjilla crop.
