The symptomatology and control measures of BCMV, BYMV, BGMV, and bean chlorotic mottle virus are briefly described. General aspects regarding the genetic control of viruses and the use of chemicals to control insect vectors are discussed. Some bean lines and/or var. resistant to BCMV, BGMV, and b...

Geminiviruses are small plant viruses that encapsidate a single-stranded circular DNA and form double-stranded DNAs in infected plants. Infection of economically important hosts with cloned DNAs of geminiviruses frequently has been difficult. Four isolates of bipartite bean-infecting geminiviruse...

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...
