COINCIDENCIA EN LA SELECCIÓN PARTICIPATIVA DE VARIEDADES DE FRIJOL COMÚN Y LA SELECCIÓN POR RENDIMIENTO EN UNA FERIA DE AGROBIODIVERSIDAD.

Despite participatory varietal selection (PVS) as a concept is every time more widely implemented in different areas from Cuban agrarian sector, the existing information concerning its effectiveness is not yet enough; therefore, this work study was aimed to help improve information for the specific case of grain crop, taking kidney beans as a reference point, extensively grown by Cuban farmers. Consequently, in September 2004, a demonstrative plot with 46 bean varieties was seeded in "Osvaldo Sínchez" farmland, Güines, Havana. Some days before crop harvest, farmers were called to celebrate diversity fair and practice PVS. Results were compared with breeders' selection based on yield at selection pressures between 95 and 5 % of the total population presented in the fair, which was calculated from the total production weight of each variety. Among other aspects, in general, high percentages of selected varieties were recorded for their yield that were also selected by farmers for each selection pressure evaluated; such a coincidence, particularly analyzed by every farmer, achieved from mid to low values, so proving that they apply different criteria and show distinct preferences for one or another variety.
