Six hundred seventy isolates of M. grisea collected from 13 provinces in China from 1998 to 2003 were tested for their mating type and fertility with four standard tested isolates. Results showed that two mating types, MAT1-1 and MAT1-2, exist in China. The percentage of fertile isolates was 40.3% on average. Amongst the fertile isolates, 21.9% had MAT1-1, and 18.4% had MAT1-2. The rate of perfect stage formation was very different among the tested isolates.
