Coincidencia en la selección participativa de variedades de frijol común y la selección por rendimiento en una feria de agrobiodiversidad
Main Article Content
Abstract
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 Sánchez�?� 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.
