Preliminar study on virus diseases of wild potatoes in the Central Platou of Mexico

Wild potato plants with mosaic and yellow sopts symptoms were detected ar the Zoquiapan National Park (Rio Frio-Nacamilpa) and at the east and west slopes of the "Nevado de Toluca", PVX was detected in wild potatoes growing within the cultivated ones (Rosita and Montsama), which had high p...

Summary:Wild potato plants with mosaic and yellow sopts symptoms were detected ar the Zoquiapan National Park (Rio Frio-Nacamilpa) and at the east and west slopes of the "Nevado de Toluca", PVX was detected in wild potatoes growing within the cultivated ones (Rosita and Montsama), which had high percentages of PVX (97 and 98) at Santa Isabel Tlaxcala. The same virus was not detected in disease habitats where cultived potatoes were not found. PVX was only detected in wild potatoes growing within commercial potatoes in Zoquiapan National Park and at the west side of the "Nevado de Toluca". PVX was not detected in isolated natural habitats, far from the cultivated potatoes. Apparently the virus is transmited from the cultivated to the wild potato species, used as reservoirs. Plantas de papa silvestre con mosaico y algunas con manchas amarillas se detectaron en el parque nacional Zoquiapan (Rio Frio/Nanacamilpa) y en las laderas oriental y occidental del Nevado de Toluca. El virus X de la papa (VXP) se detecto en papas silvestres creciendo junto a las cultivadas (Rosita y Montsama), las cuales tuvieron porcentajes muy altos de PVX (97 y 98) en Santa Isabel (Nanacamilpa). Este virus no se detecto en los habitats alejados de las papas cultivadas. En la ladera occidental, al igual que en el parque nacional Zoquiapan, el PVX se encontro solamente en papas silvestres creciendo dentro de los cultivos comerciales de papa; el PVX no se detecto en los habitats naturales alejados de las papas cultivadas por lo que se esta pasando de las papas cultivadas a las silvestres usadas como reservorios. Este estudio se realizo bajo condiciones de campo, invernadero y laboratorio, utilizando la tecnica de inmunosorbencia con enzimas conjugadas (ELISA), latex, plantas indicadoras y ocasionalmente el microscopio.
