Conservación de la diversidad de yuca en los sistemas tradicionales de cultivo de la Amazonía

Abstract : Cassava is crucial for the food security of hundreds of millions of people around the world. Even though the main source of propagation of the crop is through asexual seed by stakes (stems-cuttings) a relative high intraspecific diversity has been identified, mainly in the traditionally managed cultivation systems. Some studies on the diversity of cassava, based on molecular and morphological markers, are documented focusing on those made in the Amazon in this review. Also, the main factors that have determined the use and conservation of this diversity are exposed, such as the spontaneous appearance of seeds of sexual origin, the system of indigenous chagras, the biocultural memory and the ease of seed exchange between communities. From this perspective, it is evident that in traditional management systems the conservation and use of intraspecific diversity is a priority element that has been lost in large-scale farming systems. In traditional management systems, there is an ethnobotanical link that survives and invites us to seek alternative practices that ensure the maintenance of diversity, allowing efficient productivity and even better management to reduce the risk of incidence of some pests and diseases.
