During early 1986 computer programs were written to manage the expt. part of the bean database. In mid-year the programs were redesigned and recompiled to better access the data. In all, some 53 new dialogs were written to facilitate consultation of the bean database. All of the bean evaluation n...
A principios de 1986, se elaboraron programas de computador para manejar la parte de expt. de la base de datos de frijol. A mediados del mismo ano, se redisenaron y recopilaron dichos programas para tener un mejor acceso a los datos. En total, se elaboraron 53 dialogos para facilitar la consulta ...
Research work carried out by CIAT in 1980 and results obtained are briefly analyzed: acquisition, evaluation, and distribution of germplasm; bush and climbing bean improvement; resistance to viral (BCMV, BYMV, soybean mosaic virus, bean chlorotic mottle virus, and BGMV), fungal (rust, anthracnose...
