From 2004 to 2005,identification of 18 rice new varieties resistant to Magnaporthe grisea were carried out by artificial inoculation in greenhouse and natural inducing in field in Fujian Province.The results showed that tested rice new varieties resistant to Magnaporthe grisea populations isolated before 1996 were higher than to ones isolated in 2003 and 2004.Rice blast fungi isolated from Ningde,Sanming,Longyan areas had stronger virulence to rice new varieties.Identifications results of rice cultivars resistant to seedling blasts in greenhouse was similar to neck blasts in field.By analysis and evaluation,resistance of rice varieties Yixiangyou 673,Dyou15 and Gangyou148 were stronger,and could be applied in production.
