[ES] Se evaluó la presencia del virus del mosaico común (BCMV) en una colección de 286 entradas de Phaseolus vulgaris L., de diferente procedencia y en condiciones de campo. Una gran proporción de las variedades autóctonas de La Coruña (Noroeste de España) presentaron reacción positiva para BCMV. Por otro lado, no se encontró relación entre el tipo de semilla y síntomas de BCMV, aunque variedades de judía de semilla negra y marrón desarrollaron en su mayoría reacción negativa al BCMV. La evaluación de germoplasma de judía común en condiciones de campo reveló un gran número de variedades como posibles fuentes de resistencia, aunque estos resultados podrían estar confundídos con el ambiente o debido a la existencia de reacciones cruzadas, y deberían ser confirmados en otras condiciones y con inoculación artificial.
[EN] Resistance to bean common mosaic virus (BCMV) was evaluated among a collection of 286 accessions of Phaseolus vulgaris L., that belonged to different origin, under field conditions. The majority of bean landraces from La Coruña (Northwest of Spain) were positives for BCMV. There were no relation between seed color and suceptibility to BCMV, although most of the black and brown-seeded landraces had a negative result for BCMV. Field screening of bean germplasm under field conditions revealed a large number of genotypes with possible potential as sources of resistance. However, these results could be confused by the environment, and these materials should be confirmed again and under mechanical inoculation.
Trabajo presentado en las XI Jornadas de selección y mejora de plantas hortícolas, celebradas en Córdoba (España), entre el 21 y el 23 de octubre de 1998.- 5 páginas y 2 tablas.
