| description | During 1984 several types of interspecific crosses between Phaseolus vulgaris and P. coccineus, generated in the collaborative project with the U. of Gembloux, Belgium, were tested to evaluate their yield potential. Significant differences were observed between the crosses tested and among sister lines for traits such as yield, disease resistance, vigor, plant architecture, raceme length, seed size and color. Also, 3 successive generations (C3 to C5) of the tetraploid hybrid P. acutifolius x P. vulgaris were grown in the field at CIAT-Palmira; resistance close to immunity to bacterial blight was identified in the cross G 40034 x Bico de Ouro. In Rio Negro (Colombia), a P. coccineus multiplication nursery was established which involved 330 accessions from the P. coccineus collection for evaluation and seed multiplication. (CIAT) |

(CIAT) Durante 1984 se estudiaron varios tipos de cruzamientos interespecificos entre Phaseolus vulgaris y P. coccineus generados en el proyecto colaborativo con la U. de Gembloux, Belgica, para evaluar su potencial de rendimiento. Se observaron diferencias significativas entre los cruzamientos evaluados y entre las lineas hermanas en caracteristicas como rendimiento, resistencia a enfermedades, vigor, arquitectura de la planta, longitud del racimo y tamano y color de la semilla. Tambien se cultivaron en el campo en CIAT-Palmira 3 generaciones sucesivas (C3 a C5) del hibrido tetraploide P. acutifolius x P. vulgaris; se identifico una resistencia cercana a inmunidad al anublo bacteriano en el cruzamiento G 40034 x Bico de Ouro. En Rio Negro (Colombia), se establecio un vivero de multiplicacion de P. coccineus, el cual incluyo 300 accesiones de la coleccion de P. coccineus para evaluacion y multiplicacion de semilla.
