525 pairs of common wheat SSRs primers distributed in the total genomes of T.aestivum were used to identify the transferability in Thinopyrum intermedium and to analyze the genetic relationship between T.aestivum and Thinopyrum intermedium.The results were as follows:202 pairs SSRs primers amplified polymorphism between T.aestivum and Thinopyrum intermedium,which polymorphic percentage was 38.4%.And the polymorphic percentage between T.aestivum on genome A,B,D and Thinopyrum intermedium was 34.6%,36.9% and 42.2% respectively.These results showed that wheat SSRs primers can be used in Thinopyrum intermedium;the genetic relationship between T.aestivum on genome D and Thinopyrum intermedium was far than that of on genome A,B,which indicated that there was genetic differentiation within T.aestivum genome A,B,and D.
