Abstract:
Forty four isolates Fusarium oxysporum from melon in various areas of the Northeast were used as test materials,the genetic diversity were analyzed by SRAP,in order to explore the relationship between genetic diversity and geographical origin.The results indicated that 8 pairs primers which had rich product sand high polymorphism were selected，generated a total of 53 reproducible bands，53 of which were polymorphic,and similarity coefficient was 100%，with an average of 6.63 for each pair of primers.By cluster analysis,the similarity coefficients of 44 strains Fusarium oxysporum were ranged from 0.47 to 0.98,rich genetic variation existed among the tested isolates and there was no correlation between SRAP group and the geographic origin.
