Abstract
In October 1994, sprouting inhibition of anemone (Anemone coronaria L.) tuber was found at Tsu city. One species of Rhizopus was isolated from the affected tuber. The morphological characteristics and optimum temperature of mycelial growth of the fungus closely fit the C.M.I. descriptions of Rhizopus oryzae Went et Prinsen Geerligs. The pathogenicity of this isolate to anemone tubers was confirmed and the disease was named tuber rot. This is the first report of tuber rot of anemone caused by R. oryzae in Japan.
