Abstract:
Sixty-four strains from diseased plants and soil of Phytophthora sojae have collected from different soybean production district of Heilongjiang from 2008 to 2009. Ten independent types were identified with a set of international universal differential hosts and the virulence types and distribution of different strains inform each sampled district were elucidated. The hypocotyl inoculation method was adopted to identify resistance reaction of seventy-three soybean cultivars to different strains of Phytophthora sojae, twenty-nine cultivars resist to more than four strains of Phytophthora sojae were identified. The soybean 07-1-1is resist to strains of isolates from No. 1, 3, 11, 21, 24, and proved to be the best resistance line in the new lines identified.
