Genetic Diversity Analysis of Strains of P.oryzae in Heilongjiang Province
The genetic diversity of 181 strains of P.oryzae isolated from 20 P.oryzae blast samples in Heilongjiang Province was analyzed by 11 pairs of SSR primers.The results showed that the tested strains could be divided into 11 genealogies at the similarity level of 72%,and theⅡgenealogies were the dominant genealogies,which accounted for 54.71% of the total strains.The strains of P.oryzae collected from different plants in the same location were closely related,but the degree of differentiation of P.oryzae physiological small species in different regions was different,because it was related to the local topography.The more complicated the topography,the more complicated the differentiation of P.oryzae in the region was.
