INTERACTION OF BC-U GENE WITH RECESSIVE RESISTANCE GENES IN DIFFERENT GENETIC BACKGROUNDS FOR CONTROL OF BEAN COMMON MOSAIC VIRUS AND BEAN COMMON MOSAIC NECROSIS VIRUS

摘要

Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) are two related but distinct seed-borne potyviruses transmitted by aphid vectors. Infection causes severe yield loss in common bean worldwide. Four recessive loci bc-1, bc-2, bc-3, and bc-u, and associated alleles be-J2 and bc-22, and the dominant / gene have been associated with BCMV and BCMNV resistance (Drijfhout 1978; Melotto et al. 1996; Miklas et al. 2000; Naderpour et al. 2010). Our objective was to further characterize interactions of bc-u with the other resistance genes.
