| description | Important aspects related to the genetics and cytogenetics of cassava are reviewed. One of the most appropriate techniques for genetic recombination in cassava is polycrossing; breeding methods most commonly used are clonal selection and directed crossbreeding. Indications are also given of floral structure, flowering habit, and pollination of the cassava plant. The most promising breeding methods to obtain desirable genotypes are reviewed, namely improvement of plant populations either within populations (selection between and within families of half-siblings or full- siblings, recurrent selection) or between populations and interspecific hybridization. Some nonconventional breeding methods such as the induction of mutations and tissue culture are indicated. (CIAT) |

(CIAT) Se revisan los aspectos mas importantes relacionados con la genetica y la citogenetica de la yuca. Se observa que una de las tecnicas mas apropiadas para la recombinacion genetica en yuca es el policruzamiento; los metodos de mejoramiento mas utilizados han sido la seleccion clonal y el cruzamiento dirigido. Tambien se dan indicaciones sobre estructura floral, habito de floracion y polinizacion de la planta de yuca. Se revisan los metodos de mejoramiento mas promisorios para la obtencion de genotipos deseables: el mejoramiento de poblaciones ya sea intra (seleccion entre y dentro de familia de medios hermanos y de hermanos completos, seleccion recurrente) o interpoblacional y la hibridacion interespecifica. Se indican algunos metodos no convencionales de mejoramiento como la induccion de mutaciones y el cultivo de tejidos.
