The bean cultivar, Great Northern 1140, was inoculated with 82 isolates of bean yellow mosaic virus (BYMV) and found resistant to all the isolates of the severe strain (BYMV-S) and pea virus 2 (PV2). Resistance to BYMV-S in Great Northern 1140 is conditioned by a single recessive gene, designated by-3.
