Xpm has been considered a medium risk pathogen due to the high diversity indexes and the high migration rates of its populations. Traditionally, adult cassava plants grown in the greenhouse have been used to determine the pathogenic behavior of Xpm isolates. In this work in vitro grown cassava plants were used to determine the resistance or susceptibility to three Xpm isolates and the results were compared with the same test with adult cassava plants. The results show that, although the values of AUDPC are higher for in vitro plants, there is a correspondence regarding the determination of resistance or susceptibility compared with adult plants.La bacteria fitopatógena Xanthomonas phaseoli pv. manihotis (Xpm) es el agente causal de la bacteriosis vascular de la yuca, enfermedad que se ha reportado en todas las regiones donde se cultiva yuca. Xpm se ha considerado un patógeno de riesgo medio debido a los altos índices de diversidad y a las altas tasas de migración que presentan sus poblaciones. Tradicionalmente, para la determinación del comportamiento patogénico de aislamientos de Xpm se han empleado plantas de yuca obtenidas a partir de estacas y crecidas en invernadero. application/pdfhttps://creativecommons.org/licenses/by-nc-sa/4.0Añublo bacterianoAUDPCBacteriosis vascular de la yucaXanthomonas axonopodis pv. manihotisAUDPCCassava bacterial blightXanthomonas axonopodis pv.
