Abstract

Five Pythium species (P. paroecandrum, P. spinosum, P. sylvaticum, P. ultimum, and an unidentified Pythium sp.) were isolated from the embryos and the endosperms of ungerminated corn seeds grown in corn monoculture soils at 10 C. In inoculation tests, all five Pythium species were pathogenic to corn. In the Hokkaido district of Japan, Pythium spp. are considered to be responsible for the occurrence of seed rot of corn.
