Online resources: In: Revista Brasileira de GeneticaSummary: El muestreo ambiental para la evaluacion del germoplasma es un factor importante para el exito de las recomendaciones de un cv. para una especie comercial de cultivo. Con base en los datos de rendimiento de granos de frijol, se presenta una definicion de las localidades claves para el ensayo de las lineas avanzadas obtenidas en un programa de mejoramiento. Mediante la evaluacion de la significancia estadistica de los genotipos por la interaccion de localidades. Se selecciono un grupo de localidades contrastantes que mejor representan a la poblacion ambiental para la cual se haria la recomendacion. En las pruebas, las localidades claves para la evaluacion del frijol mulatinho fueron Irece (Bahia), Aracaju (Sergipe) y las areas de Goiania (Goias) con suelos con fertilidad alta y prom.

Based on grain yield data of the common bean, a definition of key locations for testing advanced lines obtained from a breeding program is presented. Through the evaluation of the statistical significance of the genotypes by locations interaction, it was possible to select a group of contrasting locations that better represent the environmental population for which the recommendation would be made. In our tests key locations for the evaluation of the mulatinho type common bean, were Irece (BA), Aracaju (SE) and areas of Goiania (GO) with high and average fertility soils. (AS)
