- Abstract:
- In order to study the virulence differentiation of Plasmopara viticola at the eastern foot of Helan Mountain，40 different strains of P.viticola were collected from different regions at the eastern foot of Helan Mountain．Their pathogenicity were tested by infecting three kinds of grape varieties with different resistance by leaf disc method．The results indicated that all the 40 strains had pathogenicity．The 40 strains were divided into three categories including 13 strains (32.50%) with higher resistance,22 strains (55.00%) with medium resistance,5 strains (12.50%) with susceptible resistance via identification of resistance and cluster analyses.The results showed that the pathogenicity had obvious differences.This difference might be caused by the host.
