Interpretive Summary: Bean golden yellow mosaic virus (BGYMV), a virus transmitted by the whitefly, can cause significant reductions in common bean seed yield in Central America and the Caribbean. Bean common mosaic virus (BCMV) is a seed-borne disease that can also causes yield loss in susceptible cultivars. In Puerto Rico, bean cultivars such as ‘Morales’ and ‘Verano’ have resistance genes that provide resistance to both BGYMV and BCMV. Unfortunately, these varieties do not have resistance to the Bean common mosaic necrosis virus (BCMNV), which arrived in the Dominican Republic and Haiti during the past decade. The release of ‘Beníquez’ thus fulfills a major objective of the bean breeding program at the University of Puerto Rico, through the release of a white bean cultivar that combines resistance to BGYMV, BCMV and BCMNV.

Technical Abstract: Bean golden yellow mosaic virus (BGYMV), a whitefly [Bemisia tabaci (Gennadius)]-transmitted begomovirus, can cause significant reductions in common bean (Phaseolus vulgaris L.) seed yield when susceptible bean cultivars are planted in Central America and the Caribbean. Bean common mosaic virus (BCMV) is a seed-borne disease that can also cause yield loss in susceptible cultivars. In Puerto Rico, bean cultivars such as ‘Morales’ and ‘Verano’ have the bgm-1 and I resistance genes and the SW12 QTL that provide resistance to BGYMV and BCMV. Unfortunately, Bean common mosaic necrosis virus (BCMNV), which arrived in the Dominican Republic and Haiti during the past decade, can cause a top necrosis reaction in bean cultivars that have an unprotected I gene. Bean lines that possess the dominant I and the recessive bc-3 genes have resistance to all known strains of BCMV and BCMNV. Therefore, a major objective of the bean breeding program at the University of Puerto Rico has been the development and release of a white bean cultivar that combines resistance to BGYMV, BCMV and BCMNV.
