Fusarium graminearum isolates collected from China, Nepal, Europe and USA were selected for this study. It was the first time to analysis the isolates at molecular level with AFLP, SCAR, SSCP and species-specific PCR technology to reveal genetic diversity of the isolates and compare the difference of the isolates from several continents.
Species-specific PCR revealed that there were six types of PCR fragments based on their size among the isolates analysed (type 1 to 6) from different continent. T...
