Viruses causing severe mosaic, epinasty, defoliation, and premature death of Passiflora spp. were isolated from west central Colombia. Western blot analyses indicated the presence of potyviruses. Two Colombian isolates (COL-22 and -GR) were compared to known potyviruses as to host range, symptoma...

The number and weight of seeds produced per plant were significantly (P = 0.01) reduced, 47.5 and 56.3%, respectively, in Diacol-Calima bean (Phaseolus vulgaris) plants infected with bean southern mosaic virus (BSMV). The number of pods per plant, on the contrary, was often higher in systemically...

The inheritance of the ability of Sogatodes oryzicola to support replication of the rice hoja blanca virus (RHBV) was studied by following the segregation of progeny of crosses between insects of known pedigree and known ability to support virus replication and transmission. Virus transmission to...

One necrosis-inducing strain and four mosaic-inducing strains of bean common mosaic virus (BCMV) were differentially seed-transmitted in 14 mosaic-susceptible bean (Phaseolus vulgaris) cultivars. Dubbele Witte, Redlands Greenleaf B, Michelite, Sanilac, and Red Mexican 35 consistently transmitted ...

Bean germplasm was evaluated at CIAT for resistance to BCMV strains NL-4, NL-3, and NL-5 in order to use them in the national breeding and selection programs in Africa, Europe, USA, and Chile. Ninety-eight lines were selected for an international Bean Common Mosaic/Black Root resistance nursery. ...
The molecular characterization of bean-infecting geminivirus is provided to determine their relationship with each other and to other whitefly-transmitted geminiviruses. A report is presented on the cloning of the entire tripartite genomes of bean-infecting geminivirus: mechanically transmissible...
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...
