Dr. Jim Myers and Erron Haggard, are working toward the introgression of resistance to white mold (Sclerotinia sclerotiorum) from the runner bean (Phaseolus coccineus) into the common bean (P. vulgaris). Examination of two lines from our collection of white mold resistant Phaseolus, Herbert Lamprecht?s interspecific hybrids L192 and MO162, caused us to turn our attention to the accessions PI 527828 ? PI 527873 as possible sources of resistance derived from P. coccineus and already incorporated into a P. vulgaris background. In 2005, we tested these 46 accessions for resistance to white mold in greenhouse straw tests(Petzholdt and Dickson, 1996 method). Our results indicate the presence of partial resistance in several lines comparable to the resistant check G122, with one line significantly more resistant.
