Con el objetivo de analizar el flujo de genes entre frijol común silvestre y cultivado, se determinó el porcentaje de alogamia en condiciones naturales de crecimie nto del frijol silvestre y en estación experimental. En el 2004 se evaluó el cruzamie nto natural entre frijol silvestre mexicano G23...

Interest in bean genetic resources of Central America has resumed because of disease pressures (e.g., web blight, BGMV) and limitations of current bean varieties. As most of the diversity in landraces has been explored, focus is now on the exploration of wild forms of the primary gene pool and wi...

A survey was carried out in Central Costa Rica in Jan. 1987, in an attempt to find web blight resistance in native var.; 43 samples representing 10 different taxa were found. Wild P. vulgaris was found in 2 different places in the province of San Jose; both populations presented truly wild charac...
