In 1984 the breeding for enhanced N fixation in agronomically acceptable bean cv. was continued. RIZ lines 10, 13, and 29 are performing well in international nurseries. They have high yield, good grain type, broad adaptation, and some disease resistance; however, it is difficult to assess if the...
En 1984, se continuo el mejoramiento para incrementar la fijacion de N en cv. de frijol agronomicamente aceptables. Las lineas RIZ 10, RIZ 13 y RIZ 29 se comportan bien en viveros internacionales. Presentan altos rendimientos, buen tipo de grano, amplia adaptacion y alguna resistencia a enfermeda...
Scientific training at CIAT continues to support the efforts of researchers particularly with respect to the training of technicians in the evaluation of promising germplasm. For training outside CIAT headquarters, greater emphasis was given to the study of limiting bean production factors at the...
La capacitacion cientifica en CIAT continua apoyando los esfuerzos de los investigadores, particularmente en relacion con la capacitacion de tecnicos para la evaluacion de germoplasma promisorio. En la capacitacion en sedes fuera de CIAT, el mayor enfasis se dio al estudio de los factores limitan...
During 1984, intensive on-farm trials were conducted in northern, southern, and central Narino, Colombia, and emphasis was given to the continuation of var. trials and their expansion to determine economic levels and to verification trials. In northern and central Narino, a limited no. of verific...
Durante 1984 se realizaron intensos ensayos a nivel de finca en el norte, centro y sur de Narino, Colombia; se dio enfasis a la continuacion de los ensayos var. y a su expansion para determinar los niveles economicos y a los ensayos de verificacion. En el norte y centro de Narino se sembraron un ...
The activities on character deployment involve the recombination or use of desirable characters (e.g., level of resistance to diseases and insect pests, tolerance to drought, ability to fix atmospheric N) in commercial cv., according to the needs of the particular production region for which the ...
Las actividades en despliegue de caracteres involucran la recombinacion o uso de caracteres deseables (como nivel de resistencia a enfermedades y plagas, tolerancia a sequia, capacidad fijadora de N atmosferico) en cv. comerciales, de acuerdo con las necesidades de la region productora especifica...
The CIAT Bean Program uses a 3-stage progeny evaluation program asfollows: (a) the VEF, which in 1984 contained 1004 entries distributed in 10 groups according to seed color and size, growth habit (bush or climbing), and climatic adaptation; (b) the EP, which consisted of 446 entries and 38 contr...
El Programa de Frijol del CIAT utiliza un programa de evaluacion de progenie de 3 etapas como sigue: a) el VEF, que en 1984 contenia 1004 entradas distribuidas en 10 grupos segun el color y tamano de la semilla, habito de crecimiento (arbustivo o voluble) y adaptacion climatica; b) el EP, que con...
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...

The search for new sources of resistance to Empoasca kraemeri, Acanthoscelides obtectus, Zabrotes subfasciatus, and Apion godmani among bean germplasm materials continued in 1986. Special emphasis was placed on the study of mechanisms of resistance to E. kraemeri, A. obtectus, and Z. subfasciatus...
