Resumen
Descripción
Participatory Plant Breeding (PPB) was aimed at strengthening local seed systems through introducing genetic diversity and farmers' participation into varietal selection, according to their biophysical and socioeconomic situation. Therefore, it is essential to develop methodologies that allow understanding the genetic diversity and handling characteristics of the local systems of maize, farmers' selection approaches, as well as the possible impact of local varieties on other productive systems. The main objective of this work was to estimate the impact of maize materials derived from different seed systems on the participatory varietal selectionof a productive system located in Batabanó, Havana, which is characterized by a homogeneous agriculture that depends on the formal seed system. The evaluated Cuban maize germplasm showed a high morphological diversity under the homogeneous environmental conditions of Batabanó. At the same time, a participatory seed selection made by those farmers proved the great diversity of selection approaches, local varieties coming from the seed systems of El Tejar-La Jocuma, Pinar del Rio, standing out as the most selected ones. Starting from the seed selection system of La Palma, as well as others coming from the formal and informal seed systems of Cuban germplasm, the significance of enabling the access to farmers¿ genetic diversity is confirmed, as a way for productive system diversification.
