'Bribri' small red bean (Phaseolus vulgaris L.) (Reg. no. CV-201, PI 619437) was developed by the Escuela Agricola Panamericana (EAP), Zamorano, Honduras, and released in Costa Rica by the Bean Research and Technology Transfer Program (PITTA-Frijol, acronyms in Spanish) in July 2000 as a good yielding, well adapted to low soil fertility, and disease resistant cultivar.
Bribri was an F^sub 2:6^ derived line from the cross RAB310/ XAN155//DOR3911`Pompadour G'. RAB310, XAN155 and DOR391 are small red bean breeding lines derived from the crosses DOR364/SEL277/BAT1514, BAT930/BAT93 and DOR367//DOR364/IN101, respectively (CIAT, 1995). Pompadour G is a red mottled landrace collected by the Bean/ Cowpea CRSP Program in the Dominican Republic. DOR lines mentioned here were selected as resistant to the bean golden yellow mosaic virus (BGMYV) (Beebe et al., 1996).
The F^sub 1^ was advanced in a screen house facility. Individual F^sub 2^ plants were selected under field condition at Zamorano for erect plant architecture, early-intermediate maturity, and commercial small red, race Mesoamerica seed type. The F^sub 3^ to F^sub 6^ were evaluated at Zamorano during 1992-1993, for the previously mentioned traits, as well as for resistance to natural incidence of Beancommon mosaic virus (BCMV) and anthracnose [caused by Colletotrichum lindemuthianum (Sacc. & Magnus) Lams.-Scrib.], and artificial inoculations with local isolates of common bacterial blight (CBB) [caused by Xanthomonas campestris pv. phaseoli (Smith) Dye]; the best plants from the selected families were harvested in bulk. The selected F^sub 6^-F^sub 7^ families were screened for resistance to BGYMV in field trials conducted at Comayagua, Honduras. Advanced lines trials were conducted in 1994 at five different...
