Technical Abstract: The National Melon Research Group met with the Cucurbitaceae 2010 conference in Charleston, South Carolina at 7:00 P.M. on November 17. The discussion was focused solely on cucurbit powdery mildew (CPM). Several reported increased problem with CPM or apparent changes in race. Ales Lebeda (Palacký University, Olomouc, Czech Republic) provided and overview of a proposal for an uniform, objective system for differentiation and designation of pathotypes and races (Lebeda et al., 2008; Lebeda et al., 2011). Representatives of several seed companies present indicated interest in collaborating to increase seeds of the pathotype and race differentials. Charles Block (North Central Regional Plant Introduction Station, Ames) and Gary Pederson (Southern Regional Plant Introduction Station, Griffin) stated that seeds of differentials could be distributed by the USDA, ARS, National Plant Germplasm System (NPGS) from requests submitted on-line via Germplasm Resources Information Network (GRIN).
