MARQUEZ, M; VALDES, N; PEREZ, D  y  ORTIZ, R. Impacto del fitomejoramiento participativo como parte de la innovación agropecuaria local por difusión de diversidad genética en sectores agrícolas de Pinar del Río. cultrop [online]. 2009, vol.30, n.2, pp. 00-00. ISSN 0258-5936.

A survey of species and varieties was performed in 17 farms from La Palma municipality, over the areas involved by Participatory Plant Breeding (PPB) project. The study was aimed at analyzing how much the municipal agriculture ecosystem has been improved by introducing diversity. Margalef´s specific diversity and Shannon-Weiner’s specific richness indexes were calculated, besides considering three stages: previous to PPB, after PPB, and when implementing the Local Agricultural Innovation Program (PIAL). Results showed that diversity has increased with time, mainly regarding grain, garden and vegetable groups; farmers adopt diversity according to their own interests, ecosystems are still ready for adopting new species and varieties, also the diversity introduced has led to ecosystem stability.

Palabras clave : plant breeding; participation; biodiversity.
