In order to evaluate the genetic relationships between glutinous sorghum germplasms, 25 pair of SSR markers were used to analyze the genetic diversity of29 varieties. The result showed that a total of 59 alleles were identified with an average of 2.28 alleles per locus. The average effective number of alleles（NE） was1.81.The average polymorphism information content（PIC） varied widely from 0.17 to0.62 with an average value of 0.34.The similarity coefficients of the 29 glutinous sorghum germplasms ranged from 0.203 to 0.949 with an average value of 0.593.Clustering analysis with UPGMA showed that the varieties could be divided into two groups at the genetic similarity coefficient of 0.475.The varieties from different geographic originswere clustered into one subclass, and the varieties with similar agronomic traits were clustered into one subclass, which indicated that the genetic relationships among materials was not in accordance with their geographical origins,and the glutinous sorghum germplasm resources showed abundant genetic diversity in the study.
