Abstract
The dominant resistance gene, Bct, in common bean (Phaseolus vulgaris) confers qualitative resistance to Beet curly top virus, a leafhopper-transmitted geminivirus in the genus Curtovirus. To determine whether this gene confers resistance to other geminiviruses, bean plants of a recombinant inbred population were sap-inoculated with Bean dwarf mosaic virus (BDMV), a whitefly-transmitted bipartite begomovirus in the genus Begomovirus. Results indicated that Bct (or tightly linked gene) is associated with quantitative resistance to BDMV; thus, the Bct locus is associated with resistance to a bean-infecting begomovirus and curtovirus. The difference in the nature of the resistance to these geminiviruses may indicate a role for minor genes in begomovirus resistance or differences in the virus–host interaction. The Bct locus, whether it acts alone or represents a cluster of tightly linked genes, will be useful in breeding for broad-spectrum begomovirus resistance in common bean.
