From 2007 to 2009,223 isolates of Magnaporthe grisea were collected in different parts of Fujian,China.The virulence of these isolates was assayed with Chinese race differentials,CO39 near-isogenic lines(NILs) and LTH NILs.The results showed that these 223 isolates could be classified into 20 physiological races by the Chinese race differentials,or 18 and 23 pathogenic types by CO39 NILs and LTH NILs.The dominant physiological race was ZB13 with occurring frequency of 26.91%,and the dominant types were I34.1 and J76.2 with occurring frequency of 47.09% and 41.26%,respectively.It seemed apparent that the dominant physiological race of M.grisea found in Fujian remained basically unchanged.
