| dcterms.abstract | Since considerable progress has been made in the yielding ability and disease resistance through single-trait selection of cassava material for HI, branching type, or resistance to CBB (Xanthomonas campestris pv. manihotis) and superelongation [Sphaceloma (Elsinoe) manihoticola], emphasis in selection has gradually shifted towards overall performance over several years at each selection site. Production of hybrid seeds by controlled pollination was increased 4-fold after critical pest problems were overcome. (CIAT) | en_US |
| dcterms.abstract | Debido a que se han obtenido considerales progresos en la capacidad de rendimiento y en la resistencia a enfermedades mediante la seleccion de materiales de yuca por sus caracteristicas individuales en relacion con IC, tipo de ramificacion o resistencia a CBB (Xanthomonas capestris pv. manihotis) y superalargamiento (Sphaceloma (Elsinoe) manihoticola), el enfasis se deriva gradualmente hacia la seleccion de tales materiales por su comportamiento general durante varios anos en cada sitio. Se cuadruplico la produccion de semilla hibrida por polinizacion controlada despues de superar los problemas criticos de plagas. (CIAT) | en_US |
