sembraron ocho ensayos entre 1986 y 1987, con el fin de determinar una nueva metodología para evaluar progenies F5, de fríjol voluble (Phaseolus vulgaris L.) en el sistema
de relevo con maíz (Zea mays L.). Se encontró que el sistema de parcelas pequeñas (0,84 m2) sirve para evaluar y tamizar grandes cantidades de material en lo que respecta al rendimiento, el peso de 100 semillas, días a madurez fisiológica y días a floración, util izando cuatro replicaciones. Se obtiene así un ahorro del 77 ,76% del área sembrada, en comparación con la siembra en parcelas de seis sitios y tres replicaciones, disminuyendo de esta manera los costos de la investigación.
Colombia at 2.100 m.s.n.m. between 1986 and 1987. The objetive was to determine a new methodology for the evaluation of F5 bean (Phaseolus vulgaris l.) lines in relay intercropped planted with maize (Zeamsys l.) It was found, for advanced lines, that one hill-plots (0.84 m-2) were not useful for detecting significant differences, but for F5 materials it was found that 4 replicates allowed to detect differences. The aboye result for F5 lines will permit to save 77 .8% of the area normally used in such works, i.e. by employing 6 hill plots and 3 replicates.
