| description | Cassava is an important crop in the tropics. The Manihot genus had 98 species and no barriers for efficient reproductive isolation have been observed; therefore plant breeders have an immense gene pool to work with. Genes from wild species have already been successfully used to obtain var. resistant to CAMV, but attempts to increase root protein content have not been so successful. The availability of genes of cultivated species and the risks of working with little-known wild species notably reduce the possibility of using their genetic resources immediately. However, in the middle- and long-term, advantage should be taken of this rich and promising source of germplasm. The collection and assessment of wild species is therefore considered prioritary.

(AS- CIAT) La yuca es un cultivo importante en los tropicos. El genero Manihot tiene 98 especies y no se han observado barreras para el aislamiento eficiente con fines reproductivos; por tanto, los fitomejoradores tienen un inmenso acervo genico con que trabajar. Ya se han utilizado exitosamente genes de especies silvestres para obtener var. resistentes a CAMV, pero los intentos de aumentar el contenido proteinico de las raices no han tenido la misma suerte. La disponibilidad de genes de especies cultivadas y los riesgos involucrados cuando se trabaja con especies silvestres poco conocidas reducen notablemente la posibilidad de utilizar estos recursos geneticos en forma inmediata. Sin embargo, a mediano y largo plazo, se debe aprovechar esta fuente de germoplasma rica y prometedora. Se considera, por tanto, prioritario la recoleccion y evaluacion de especies silvestres.
