Solanum×michoacanum (mch) is a valuable source of resistance to Phytophthora infestans and has not been used in potato breeding due to crossing barriers with S. tuberosum. Somatic hybridization followed by backcrossing is a strategy for introgression of important traits from wild potato species sexually isolated from S. tuberosum. Tetraploid somatic hybrids Solanum×michoacanum (+) S. tuberosum [mch (+) tbr] and autofused 4× mch lines were crossed to several potato cultivars as male and female parents. Our results indicate that resistance against late blight, originating from mch (+) tbr somatic hybrids and autofused 4× mch lines can be transferred to cultivated potato by sexual crossing. Viable and fertile progeny was obtained providing a route to using mch as a source of resistance to P. infestans in potato breeding.ResumenSolanum × michoacanum (mch) es una valiosa Fuente de Resistencia a Phytophthora infestans y no ha sido usada en el mejoramiento de la papa debido a las barreras de cruzamiento con S. tuberosum. La hibridación somática, seguida de retrocruzas, es una estrategia para introgresión de caracteres importantes de especies silvestres de papa aisladas sexualmente de S. tuberosum. Hibridos somáticos tetraploides de Solanum × michoacanum (+) S. tuberosum [mch (+) tbr] y líneas autofusionadas 4× mch se cruzaron con varias variedades de papa como progenitores machos y hembras. Nuestros resultados indican que la resistencia contra el tizón tardío, originada de híbridos somáticos mch (+) tbr y líneas autofusionadas 4× mch pudiera transferirse a papa cultivada mediante cruzas sexuales. Se obtuvieron progenies viables y fértiles y se puede continuar investigación posterior para explorar mch como fuente de resistencia a P. infestans en el mejoramiento de la papa.
