A new wild bean found in the mountainous range "Fila Cruces" of southeastern Costa Rica is described. To date, only four populations are known from different sites on the slopes of Cerro Anguciana and "Fila Cruces" where it seems to be endemic. The differences (slender curved racemes, small oval ...

Evidence is presented about the presence of Phaseolus microcarpus in Costa Rica, while it was previously reported northwards in other Central American countries and Mexico. Fourteen populations are currently known, four from the Peninsula of Nicoya, and ten are in the tropical dry forest of the m...

New records of Phaseolus microcarpus (Leguminosae: Phaseoleae) for Costa Rica
Terminal drought is a worldwide constraint to common bean production and its negative effects will be increased by climate change. The objective of this research was to characterize phenotypically advanced lines and commercial cultivars of common bean for their resistance to terminal drought stre...

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...
