The status of the Phaseolus collection held at the CIAT Genetic Resources Unit and the results of germplasm explorations in 1985 are presented in table form. Future plans include collection activities through expeditions in the Andean region. (CIAT)

Se presentan en forma de cuadro el estado de la coleccion de Phaseolus de la Unidad de Recursos Geneticos del CIAT y los resultados de las exploraciones para germoplasma realizadas en 1985. Los planes futuros incluyen actividades de recoleccion a traves de expediciones en la region Andina. (CIAT)

During 1984 a collaborative research effort between CIAT and the National Vegetable Research Station (Wellesbourne, England) was started to broaden the knowledge of halo blight caused by Pseudomonas phaseolicola. Isolates of the halo blight pathogen were collected from bean growing areas of Latin...

Durante 1984 se inicio un esfuerzo de investigacion coloborativo entre CIAT y National Vegetable Research Station (Wellesbourne, Inglaterra), para ampliar el conocimiento del anublo de halo causado por Pseudomonas phaseolicola. Se recolectaron aislamientos del patogeno del anublo de halo en areas...

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...

During 1986, activities with Phaseolus in the biotechnology research unit focused on: developing tissue culture techniques for regeneration of bean plants using various organs and tissues; developing electrophoretic techniques for genotype identification; and monitoring research activities in asp...

Durante 1986 las actividades con Phaseolus en la unidad de investigaciones en biotecnologia se enfocaron hacia: el desarrollo de tecnicas de cultivo de tejidos para la regeneracion de plantas de frijol utilizando distintos organos y tejidos; el desarrollo de tecnicas de electroforesis para la ide...

During 1986 emphasis was given to testing promising bean germplasm for yields and the 1st materials bred at CIAT specifically for drought tolerance. Preliminary screening was performed under mild stress in the 1st semester, while exceptionally dry weather permitted evaluation under high levels of...

Durante 1986 se dio enfasis a pruebas de germoplasma promisorio de frijol por rendimiento y de los primeros materiales mejorados en CIAT especificamente por tolerancia a la sequia. La seleccion preliminar se efectuo en condiciones de estres leve en el primer semestre, en tanto que condiciones de ...

Evaluation of photoperiod bean response in flowering screening continued at CIAT-Palmira, using artificial 18 h daylengths to delay flowering. Approx. 600 germplasm accessions were evaluated in 1986 as a part of continuing efforts to characterize responses of germplasm in different bean productio...

La evaluacion de la respuesta del frijol al fotoperiodo en la seleccion por floracion continuo en CIAT-Palmira, utilizando fotoperiodos artificiales de 18 h para retrasar la floracion. Se evaluaron aprox. 600 accesiones de germoplasma en 1986 como parte de esfuerzos continuos para caracterizar re...
