Potencial de producción de líneas de frijol Adzuki (Vigna angularis) en tres localidades de Costa Rica

Production potential of adzuki bean (Vigna angularis) lines in three localities in Costa Rica. Between 1984 and 1988, fourteen adzuki bean lines were evaluated in three localities in Costa Rica: Alajuela at 840 masl., Perez Zeledon at 760 masl. and Rio Frio at 100 masl. Three common bean varieties were used as controls: Talamanca, Huetar and Mexico 80. The best adzuki lines in the three localities were U CR - 2 and U CR - 7 (red colored grain) and UCR-3 (black colored grain). In Rio Frio and Perez Zeledon, the adzuki showed a like production as the common bean, due to the low incidence of Web blight (Thanatephorus cucumeris Frank Donk). This is a fungus which slightly affects the adzuki bean, but it is a limiting factor for common bean production in these two localities. In Alajuela, an ideal zone for common bean production, several adzuki lines showed a higher productivity.
