La principal prioridad del esfuerzo en mejoramiento genetico de frijol es aumentar la produccion en las zonas donde actualmente se cultiva. El medio en dichas zonas presenta condiciones climatologicas desventajosas para el cultivo y en cambio, favorables para el complejo de enfermedades y plagas que lo atacan. Mediante la colaboracion de tecnicos en patologia, entomologia y fitomejoramiento se evalua, en forma secuencial, el material existente en el banco de germoplasma del CIAT segun la herencia y la expresion de cada caracter. Se presenta una lista de los factores que limitan la productividad y la produccion en clima calido como: BCMV, bacteriosis, Empoasca, roya, BGMV, mustia, pudriciones, exceso o escasez de agua, mala fertilidad del suelo y adaptacion a altas temp. Se describen los caracteres deseables en el mejoramiento, dificultades para su adquisicion y adelantos hasta 1979 en la obtencion de resistencias multiples para el clima calido. Se incluye una tabla de frecuencia de caracteres selectos en materiales provenientes del banco de germoplasma e hibridos evaluados segun las diferentes disciplinas. (CIAT)
The main priority of efforts in genetic improvement of beans is to increase the production in areas where it is currently cultivated. The environment in those areas has unfavorable climatic conditions for the crop and instead, favorable for the disease- insect complex attacking it. Through the collaboration of technicians in pathology, entomology and plant breeding, the material existing in CIATs germplasm bank was evaluated in a sequential order. A list is presented of the factors limiting productivity and production in warm climates such as BCMV, bacterioses, Empoasca, rust, BGMV, web blight, rots, excess or shortage of moisture, low fertility of the soil and the adaptation to high temp. A description is given on the characters desired for improvement, the dificulties for their attainment and the progress made up to 1979 on the obtainment of multiple resistance for warm climates. A frequency table is included on the characters selected from materials proceeding from the germplasm bank and hybrids, evaluated according to the different disciplines. (CIAT)
