Abstract	Late blight, caused by the oomycete pathogen, Phytophthora infestans, is a devastating disease of potatoes and tomatoes. A key long-term management strategy for combating this disease is to develop potato cultivars with broad-spectrum and durable resistance through identification and integration of major resistance genes. In support of previous results, we have determined that some accessions of the wild potato species Solanum verrucosum contain strong foliar resistance to P. infestans while others are susceptible. In addition, whole- and wounded-tuber inoculations revealed that most accessions lacked resistance to tuber infection. However, one accession (PI 570643) contained little foliar resistance but expressed tuber resistance, suggesting that expression of these two phenotypes in this species is not correlated.El tizón tardío, causado por el patógeno oomycete Phytophthora infestans,es una enfermedad devastadora de papas y tomates. Una estrategia clave de manejo a largo plazo para combatir esta enfermedad es el desarrollo de cultivares de papa con un amplio espectro de resistencia durable, mediante la identificación e integración de genes mayores de resistencia. Como respaldo a resultados previos, hemos determinado que algunas introducciones de la especie silvestre de papa Solanum verrucosum contiene fuerte resistencia foliar a P. infestans, mientras que otras son susceptibles. Además, inoculaciones a tubérculos completos y heridos revelaron que la mayoría de las introducciones carecían de resistencia a la infección de tubérculo. No obstante, una introducción (PI 570643) contenía poca resistencia foliar pero expresó resistencia de tubérculo, sugiriendo que la expresión de estos dos fenotipos en esta especie no está correlacionada.
