A set of 154 accessions of nine wild Lycopersicon spp. and five accessions of three closely related Solanum spp. were tested for resistance to tomato powdery mildew ( Oidium lycopersici ). Screening revealed valuable sources of resistance, mainly among L. hirsutum, L. pennellii, L. cheesmanii, L. chilense, L. peruvianum and L. parviflorum. L. esculentum (all ssp.) and L. pimpinellifolium expressed high susceptibility to O. lycopersici inoculation. Results of variance and cluster analysis of responses to O. lycopersici coincide with recent taxonomic classification and genetic relationships within genus Lycopersicon .
