Se han presentado brotes de enfermedades virales antes desconocidas en habichuela y en tomate en varios municipios del Valle del Cauca. Las habichuelas presentan un arrugamiento foliar severo y amarillamiento moderado, mientras que el tomate muestra síntomas moderados de mosaico y deformación fol...

Three comoviruses isolated from diseased bean plants in Brazil (CV-BZ), Venezuela (CV-VZ), and Honduras (CV-HD) were inoculated to 53 bean genotypes possessing or lacking the dominant alleles of the necrosis (I) gene, which conditions resistance to bean common mosaic virus (BCMV). These comovirus...

The inheritance of the localized necrosis, apical necrosis, and mosaic reactions induced by bean severe mosaic comoviruses in common bean (Phaseolus vulgaris L.), was studied in crosses of Great Northern 123 × Pitouco, Great Northern 123 × Iguaçu and Pitouco X Iguaçu. Great Northern 123 reacts wi...

The common bean (Phaseolus vulgaris L.) has its origin in America, where it is consider as one of the basic foods. In Cuba, the emergence of bean golden mosaic was associated with high populations of Bemisia tabaci in common bean plantings in the 1970s. Persistent infections and crop losses cause...

En los últimos años, el Valle del Cauca ha sufrido la incidencia de begomovirus en plantaciones de tomate causando el abandono de muchas áreas de cultivo. El control de estos virus ha estado enfocado hacia el control del vector pero las medidas implementadas no son totalmente efectivas. Por esta ...

The genetics of resistance to bean golden mosaic virus (BGMV) was studied in an 8×8 complete diallel cross of common bean, Phaseolus vulgaris L. The 28F1 hybrids, their reciprocals, and eight parents were artificially inoculated with BGMV under glasshouse conditions. Data were recorded and analyz...

Genetics of resistance to bean golden mosaic virus in Phaseolus vulgaris L.
Background: Even though Plasmodium vivax has the widest worldwide distribution of the human malaria species and imposes a serious impact on global public health, the investigation of genetic diversity in this species has been limited in comparison to Plasmodium falciparum. Markers of genetic dive...

A total of 44 bean (Phaseolus vulgaris L.) genotypes was evaluated for disease reactions to bean golden mosaic virus (BGMV) by mechanical and whitefly inoculation under glasshouse and field conditions, respectively. Most of the genotypes reacted similarly under both screening conditions, with a f...
