Soybean aphid (Aphis glycines) outbreaks occurring since 2000 have been associated with severe virus epidemics in snap bean (Phaseolus vulgaris) production in the Great Lakes region. Our objective was to identify specific viruses associated with the disease complex observed in the region and to survey bean germplasm for sources of resistance to the causal agents. The principle causal agent of the disease complex associated with extensive pod necrosis was identified as Clover yellow vein virus (ClYVV), designated ClYVV-WI. The virus alone caused severe mosaic, apical necrosis, and stunting. Putative coat protein amino acid sequence from clones of amplicons generated by reverse-transcription polymerase chain reaction was 98% identical to ClYVV strain no. 30 identified in Japan that has not been reported to cause pod necrosis. ClYVV-WI amplicons were 96% identical to a mild strain of ClYVV from Oregon. A distinguishing feature of this new strain is that it does not react with Potyvirus broad-spectrum monoclonal antibody PTY 1. A survey of common bean lines and cultivars revealed that, in addition to UI-31 and US1140 with known resistance to ClYVV, lines with the bc-3 gene for resistance to Bean common mosaic necrosis virus also were resistant to ClYVV-WI. An evaluation of 63 snap bean cultivars and breeding lines revealed just one, Roma 442, with a moderate level of tolerance to ClYVV-WI. Introgression of the bc-3 gene and resistances from UI-31 and US1140 into snap bean may offer a high level of resistance to extensive pod necrosis disease caused by ClYVV in the Great Lakes region.
