Abstract: [Objective][Method]In this study, In order to further analyze the breeding of good varieties of sugar beet resistant to root rot ,10 pairs SRAP molecule markers were used to investigate the relationship analysis of 11 domestic and foreign varieties pairs . [Result] A total of 85 unambiguous bands were obtained,65 of which were polymorphic. The average ratio of polymorphic bands was 76.5%. Compute over-all mean showed that genetic distance was 0.5057, genetic similarity among varieties was 0.6031. The 11 genotypes were divided into 3 cluster groups based on cluster analysis (atintercept of 0.2). [Conclusion]The results showed that the tested varieties of the domestic anti-root rot was better. TY301 (domestic), TY303 (domestic), CK-TY312 (domestic),and HI055 (foreign) anti-root rot were better and the four varieties root rot susceptibility of less than 3%
