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...

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...

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...

Bean dwarf mosaic geminivirus (BDMV) was shown to have a bipartite genome (DNA-A and DNA-B) from restriction map and sequence data comparisons of cloned DNAs. The nucleotide sequences of the infectious clones of DNA-A and DNA-B were determined. Computer analyses showed that the bipartite genome o...

The proliferation and rapid dissemination of whitefly-transmitted viruses of important food and industrial crops in Latin America, have been the consequence of drastic changes in traditional cropping systems. Some of the expanding non-traditional cash and export crops, such as soybean and several...

A selection study was conducted with 6 hybrid bean populations in 3 double groups, with low, intermediate, and high yield potential, at CIAT`s exptl. farm in Popayan (Cauca, Colombia), in a P-deficient soil with pH 4.5. These soil conditions allow for high disease incidence such as anthracnose (C...
