| description | The concept of genetic erosion is discussed, with particular reference to cassava in Brazil. National germplasm collections are listed with the corresponding no. of accessions; information is also provided on the plant breeding activities carried out. The potential of interspecific crossbreeding in cassava with wild Manihot species is discussed. In Brazil, wild Manihot species, particularly in the form of seed, are collected by the Centro Nacional de Recursos Geneticos (CENARGEN); both a small seed stock (15 species) and a small live collection (20 species) are maintained. The collection of woody wild species is considered prioritary. The interactions of CENARGEN with active germplasm collections in the country are indicated regarding collection, internal exchange, and germplasm introduction. A tentative organizational chart of a cassava germplasm collection is included. General indications are also provided on the handling of genetic resources. (CIAT) |

(CIAT) Se discute el concepto de la erosion genetica, con particular referencia a la yuca en Brasil. Se enumeran las colecciones nacionales de germoplasma con el no. correspondiente de accesiones; tambien se proporciona informacion sobre las actividades de fitomejoramiento desarrolladas. Se discute el potencial del cruzamiento interespecifico en yuca con especies silvestres de Manihot. En Brasil, el Centro Nacional de Recursos Geneticos (CENARGEN) recolecta las especies silvestes de Manihot, particularmente en forma de semilla; tambien mantiene una limitada reserva de semilla (15 especies) y una pequena coleccion viva (20 especies). La recoleccion de especies silvestres lenosas se considera prioritaria. Se indican las interacciones de CENARGEN con las colecciones de germoplasma activa en el pais en cuanto a recoleccion, intercambio interno e introduccion de germoplasma. Se incluye un organigrama tentativo de una coleccion de germoplasma de yuca. Tambien se proporcionan indicaciones generales sobre el manejo de recursos geneticos.
