Abstract:
In order to confirm the resistance of main cultivars against.Phytophthora sojae causing soybean root rot in Sanjiang plain area, identification of 13 main cultivars in Sanjiang plain to race 1 of Phytophthora sojae with pot and field test by artificial inoculation was done.The results showed that the resistance of Hefeng 55 was resistant in pot test with mortality for 27.41%, and the difference was extremely significant compared to other cultivars except for Kenfeng 16 and Suinong 28.The resistance of Hefeng 55 was resistant in field test with mortality for 3.33%, and the difference was significant compared to other cultivars except for Kenfeng 16. Decreasing rate of Hefeng 55 was 3.84% compared to the control check without inoculation, and the difference was significant. The resistance of Kenfeng 16 was resistant in pot test with mortality for 24.81%, and the difference was extremely significant compared to other cultivars except for Hefeng 55 and Suinong 28. The resistance of Kenfeng 16 was resistant in field with mortality for 6.67%, and the difference was significant compared to other cultivars except for Hefeng 55. Decreasing rate of Kenfeng 16 was 5.19% compared to the control check without inoculation, and the difference was significant. The results showed that Hefeng 55 and Kenfeng 16 were suitable to plant to control the soybean root rot causing by Phytophthora sojae in Sanjiang plain area because of their resistance were better and decreasing rates were lower.
