Abstract: Simple sequence repeats (SSRs) markers were used to detect genetic variation of 60 elite maize inbred lines. Twenty-three SSR primers giving stable amplified detected 96 alleles among the inbred lines tested. The average number of allele per SSR locus was 3.96 with an range from 2 to 7. The value of polymorphism information content (PIC) for each SSR locus varied from 0.15 to 0.80 with an average of 0.600. The UPGMA analysis classified 60 inbred lines into 6 clusters, which corresponed to the heterotic groups determined by their pedigree information and breeder's experiences (i. e. Tangsipingtou, Luda Red Cob, PN, BSSS, Lancaster, Suwan).
