Bean golden mosaic virus (BGMV) can seriously limit common bean (Phaseolus vulgaris L.) yield in some of the main production areas in Brazil. Unfortunately, up to now, no cultivars or elite lines have been developed with satisfactory levels of resistance or tolerance to the virus by conventional breeding methods. For this reason, the breeding program conducted by Embrapa is using recurrent selection (RS) as a strategy to develop carioca and black seeded elite lines tolerant to BGMV. Thus, the main goal of the present work was to identify progenies with greater parental genetic representativeness among the black seeded C2S1:4 progenies selected in this RS cycle as highest yielding and tolerant to the virus.
