varieties to evaluate tolerance to powdery mildew ( Podosphaera xanthii ) and downy mildew ( Pseudoperonospora cubensis ) infection under field conditions in 2005. Powdery mildew (PM) and downy mildew (DM) are important diseases of cucurbit crops in the mid
humid lowland tropics. Declining flower production accompanied an increase in the presence of foliar diseases, especially powdery mildew ( Podosphaera xanthii ), downy mildew ( Pseudoperonospora cubensis ), and various potyviruses ( Potyvirus ). In
mildew [ Podosphaera xanthii (Castagne) Braun and Shichkoff]. These NILs have been grown in Cabrils, in S-free greenhouse conditions, without signs of leaf necrosis. Perchepied et al. (2004) found that S susceptibility is common in melon accessions
diseases including root-knot nematodes ( Meloidogyne incognita ), bacterial fruit blotch ( Pseudomonas avenae ssp. citrulli) , gummy stem blight ( Didymella bryoniae ), and powdery mildew ( Podosphaera xanthii ) ( Davis et al., 2007 ; Gusmini et al
case is the use of Indian germplasms in breeding programs for resistance to the fungi Podosphaera xanthii and Golovinomyces cichoracearum , the main causal agents of powdery mildew in cucurbits. A preliminary study of the extant Brazilian germplasm

vectoring plant disease. For example, Herbert et al. (2009) found that the crapemyrtle aphid ( Sarucallis kahawaluokalani ) had greater fitness on cultivars and hybrids resistant to powdery mildew ( Podosphaera xanthii ). Similarly, Chappell et al. (2012
