Abstract
The inheritance of resistance to bean golden yellow mosaic virus (BGYMV) was studied in common beans ( Phaseolus vulgaris L.). The original cross was made between breeding line PR9556-158, which produces deformed pods when infected with BGYMV, and PR9556-171, which has normal pod development when inoculated with the virus. Pod type was evaluated on plants from six generations (parental lines, F 1 , F 2 , F 2:3 , F 3:4 , and backcrosses of the F 1 to both parents) at mid-pod fill (R8), ≈65 days after planting. The segregation patterns from the F 2 , F 2:3 , F 3:4 , and backcross populations were consistent with the hypothesis that a single dominant gene confers normal pod development in PR9556-171. When inoculated with BGYMV, the deformed pods of PR9556-158 produced fewer seeds per pod than PR9556-171, resulting in lower seed yield. The gene symbol Bgp-1 has been assigned for this dominant resistance gene that controls the normal pod reaction to BGYMV in common bean.
