 In: EuphyticaSummary: Las 2 enfermedades mas serias en yuca son el AMD y el CBB (Xanthomonas manihotis). El clon 58308 derivado del tercer retrocruzamiento del cruce interespecifico de yuca x cauchotero (Manihoti glaziovii) mostro un alto nivel de resistencia a ambas enfermedades. Los cruces de 58308 con algunos otros clones que variaron de susceptibles a moderadamente susceptibles para ambas enfermedades dieron progenies con una correlacion genotipica significativa entre resistencia a ambas enfermedades (r = 0.90) debida principalmente al enlace. Las hereditabilidades de resistencia a las enfermedades se estimaron en 50-70 por ciento para AMD y 25-65 por ciento para CBB. Se asume que la resistencia a ambas enfermedades es poligenica. Se estimo la respuesta correlacionada a la seleccion por AMD y CBB. (RA-CIAT)Summary: The 2 most serious diseases of cassava are CAMD and CBB (Xanthomonas manihotis). Clone 58308, derived from the 3rd backcross of the interspecific cross of cassava x ceara rubber (Manihot glaziovii), showed a high level of resistance to both diseases. Crosses of 58308 with several other clones which varied from susceptible to moderately susceptible to both diseases gave progenies with a significant genotypic correlation between resistance to both diseases (r = 0.90) apparently due to linkage. The heritabilities of resistance to the diseases were estimated at 50-70 percent for CAMD and 25-65 percent for CBB. Resistance to both diseases is assumed to be polygenic. The correlated response to selection for CAMD and for CBB was estimated. (AS)
