Title: Tagging SSR Markers for Resistant Gene to Phytophthora Root Rot in Soybean
Abstract: Phytophthora root rot is an important soybean disease,which can influence the yield.To map SSR makers link with resistant genes to soybean Phytophthora root rot,Hefeng 25 and Kangxian 2 were crossed and the F2 seperation population was obtained.350 pair of SSR primers were screened and 52 pairs have polymorphism.BSA(Bulked segregation analysis) method was used to screen the polymorphic and diverge primers,one pair of polymorphic primer,Scaa003,located on LG J was tagged.The examination rate of Scaa003 between 10 sensitive soybean cultivars and 4 resistant soybean cultivars reached 100%.Result shows that the primer has the common characteristic for the examination,it can provide the theoretic base for selecting the soybean materials which have the resistance to the soybean Phytophthora sojae Race 1.
