Abstract
This paper describes the different bud rot complex diseases in Ecuador and Colombia. Category C0731 showed a good behavior or DA 128 D AF origin in the Plantation Palmeras del Ecuador and an experiment was undertaken to define more accurately the behavior of DA 128 D descendants (duras and commercial) in extension, as well as in replanting programs. The interspecific hybrid E. oleifera x E. guineensis shows a good tolerance to bud rot. Coari (Brazil) origin hybrids were planted at large scale, first in Ecuador and then in Colombia and have shown good oil production rates. At the present time the idea is to improve these hybrids and to assess them with other E. oleifera origins for oil production. A back-crossing program is underway to integrate into E. guineensis the resistance of the American palm, E. oleifera to these diseases. Molecular biology works are being carried out simultaneously so as to look for molecular markers of resistance and sensitivity to these diseases. Se describe las varias enfermedades incluidas en el complejo Pudrición de Cogollo en Ecuador y Colombia. Se observó el buen comportamiento de la categoría C0731 de origen DA 128 D AF en la plantación de Palmeras del Ecuador y se inició ensayos para precisar el comportamiento de las plantas descendentes del DA 128 D (Duras y comerciales) tanto en extensión como en resiembra. El híbrido interespecífico E. oleífera x E. guineensis muestra una buena tolerancia al complejo. Se sembró a grande escala, primero en Ecuador y luego en Colombia, híbridos con origen Coari (Brasil) que muestran una buena producción de aceite. Se busca actualmente mejorar estos híbridos y evaluarlos con otros orígenes del E. oleífera para la producción de aceite. Actualmente se realiza un programa de retrocruzamientos para integrar en el E. guineensis la resistencia de la palma americana E. oleífera, a estas enfermedades. Paralelamente se realiza trabajos de biología molecular para buscar marcadores moleculares de resistencia o sensibilidad a estas enfermedades.
