Breeding for resistance to cassava bacterial blight at IITA - p. 11-14
Se presentan los resultados obtenidos por el IITA en Africa en la busqueda de resistencia al anublo bacterial de la yuca (CBB), durantre el periodo 1972-74. La fuente genetica de resistencia a CBB ha sido identificada y el mecanismo de resistencia parece deberse principalemente a genes cuantitativos con efectos aditivos, aunque algunos poseen efectos no aditivos. De acuerdo a los trabajos iniciados en 1972 parece que es posible obtener variedades altamente productivas con alto grado de resistencia a CBB. (CIAT) IITA has been involved in the search for resistance to cassava bacterial blight in Africa. This is a presentation of the results obtained during the period 1972-74. The genetic source of resistance to CBB has now been identified; the mechanism of resistance appears to be due to quantitative genes mainly with additive effects, although some present nonadditive effects. Based on the results of these trials, it seems possible to produce high- yielding varieties with a high level of resistance to CBB. (CIAT)
