Conteúdo: | Cassava (manihot esculenta) is the most important crop cultivated by Amerindians in the Amazon. While cassava landraces have been the focus of analysis of genetic diversity, only a few preliminary studies have attempted to relate the observed patterns to traditional cultivation practices. Our goal is to carry out both genetic and ethnological approaches in a system of traditional cassava farming. Our study was based in Rewa, a Makushi community in Guyana (South America), where observations, participation in farming, and enquiries have been conducted. The local classification mentioned 87 names of cassava landraces, which corresponded to 76 distinct varieties. In order to study the relationships between the structure of molecular diversity in landraces and the local classification, we assessed the genetic diversity of a sample of 31 landraces, using 3 to 5 acccessions per landrace, with AFLP markers.
