Selección participativa de cultivares de soya (Glycinemax, (L.)) en Los Palacios, Pinar del Río, Cuba

Abstract

Participatory selection is a simple, fast and efficient way to introduce a large cultivars number and its effectiveness in various crops is proven.Plant breeders develop more productive cultivars under ideal conditions but often do not adapt well to the specific conditions of farmers, this approach allows to increase yields, genetic diversity in the target environments and decision making of farmers in participating communities. The objective of the study was to identify the cultivars with the highest acceptance and the most taken into account agronomic criteria. In the present work the results of the participatory varietal selection of soybean are shown in a diversity fair developed in a farm in Los Palacios municipality. The most widely accepted cultivars were identified, the agronomic criteria most taken into account by the participants and the effective diversity percentage was determined. Cultivars D-2101, DT-26, DT-22 and DT-20 stand out with good behavior for the locality and the characters most taken into account at the moment of making the selection were number of grains per pod, number of pods per plant, grain size, yield, height and incidence of pests.
