Hoshiyutaka is a non-glutinous, long-culmed, late-maturing and super heavy panicle type rice variety. It was obtained from a cross between chugoku 55 (japonica) and KC89 (indica/japonica hybrid, indica type), and registered as paddy rice Norin 286 in 1987. Its typical chacreristics are long and slim shaped grain and high amylose content (about 27%). The yielding ability of Hoshiyutaka is superior to that of Nipponbare. Hoshiyutaka is resistant to rice stripe virus and blast disease and susceptible to bacterial leaf bright. Its cold tolerance is less than that of Nipponbare. Hoshiyutaka is adaptable to the fertile plains of the western part of Japan
