CARACTERIZACI�?N DE LOS SISTEMAS LOCALES DE SEMILLAS DE FRIJOL Y MAÍZ DE LA PALMA, PINAR DEL RÍO
Main Article Content
Abstract
characterized in �??El Tejar-La Jocuma�?� community, as part of a
diagnostic stage from the participatory plant breeding program
through farmers�??surveys. Farmers produce, exchange, select
and conserve seeds by apparently maintaining and preserving
diversity. They have little access to seeds derived from formal
system, their primary seed source being exchanged with other
farmers within the community. Most farmers have only one
maize landrace, «criollo» cv, that has been selected and
maintained by local farmers for many years. This variety produces
moderate yields under low input conditions and shows
resistance to the primary diseases and pests of maize in the
area. In contrast, beans present high varietal diversity on farm,
although there is a lack of resistant genes to diseases like rust,
whose occurrence has exponentially increased in the last five
years. Facilitating farmers continuous access to new varieties
may be an important means to support the incorporation of
disease resistant genes into the local seed system via gene
flow.
