    Abstract The Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP), in Zacatepec Morelos, started a genetic improvement program of wild and semi-cultivated poinsettia plants ("nochebuena de sol"). It is important to generate a phytosanitary database that allows the release of new varieties and hybrids that provide tolerance to the major pathogens reported in cultivated poinsettia plants. The phytosanitary status of the “nochebuena de sol” plants is not available in Mexico, so the objective of this research was to generate preliminary data about viruses associated to these materials. Based on DAS-ELISA and RT-PCR results, we reported More >
