摘要

The initial step in the successful implementation of a breeding program aimed at obtaining bruchid resistant beans lines is the identification of sources of resistance within a diverse germplasm. Here, a total of ninety two (92) Brazilian common bean genotypes were screened to identify promising sources of resistance to Zabrotes subfasciatus (Boheman) (Coleoptera: Chrysomelidae: Bruchinae), the primary insect pest of stored beans. The cultivars BRS Ametista and BRS Esplendor, as well as the bean lineages CHP 01-182-12-Uirapuru × Campeiro and CHP 04-241A-212-Guapo B. × Uirapuru exhibited the lowest oviposition rates. The genotypes BRS Ametista, CHP 01-182-12-Uirapuru × Campeiro and BRS Esplendor also showed the lowest average of adult emergence evidenced by the F1 progeny. In contrast, genotypes BRS Ametista, CHP 05-282-04-Campeiro × Agudo, TB-17-02, CHC 01-167-1-03, IPR Uirapuru, CHIR 14, IPR Campos Gerais, CHIC 61-Cariocão, IAC Imperador, Arcelin 1, FAP-F3-2-SEL-IAC, CAV 17 EFM008, SCS 205-Riqueza, LP 13-634-preto, IAC Harmonia and Linhagem 110-IAC exhibited the lowest percentage of larval-pupal viability. Conversely, genotypes Arcelin 3, Arcelin 1, CHIN 19, CHV 05-268-02, LP 13-84-Carioca, CNFRs-15558-Rosinha, IPR Campos Gerais, CHC 01-175-1-Campeiro × IAC Tibatã, BRS Notável, IPR Uirapuru, BRS Estilo, IPR Quero-Quero, CAV 17 EFM0006, CHP 04-241A-212-Guapo B. × Uirapuru, BRS Esplendor, and CHP 01-182-12-Uirapuru × Campeiro were observed to significantly prolong the developmental time (cycle) of Z. subfasciatus, indicating the expression of antixenosis and/or antibiosis type resistance. Thus, these genotypes are promising sources of resistance to Z. subfasciatus, and further studies are recommended to elucidate the underlying mechanisms and genes involved.
