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. ...
Methods used to identify BCMV are described in terms of symptomatology (common mosaic, black root); transmission (seed, insect, manual); responses of differential bean cv. (mosaic, systemic or local necrosis, local lesions, immunity); cytology (light and electron microscopy); purification and ser...
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...

Genetics of resistance to bean golden mosaic virus in Phaseolus vulgaris L.
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...
