Maize (Zea mays L.) is a crop of major economic importance in Iran, but most hybrids are developed in Iran by using inbreds extracted from hybrids introduced from other countries. Pedigree and genetic diversity within and relationships among the most commonly used Iranian maize inbred lines using simple sequence repeat (SSR) markers. Thirty-six Iranian inbred lines and two lines from the International Maize and Wheat Improvement Center (CIMMYT) were fingerprinted with 43 SSR markers. A total of 194 alleles, moderate levels of diversity, and a high number of unique alleles were found in these lines. UPGMA clustering grouped the Iranian inbreds into four clusters and the two CIMMYT lines formed a separate and more distant cluster. Clustering was consistent with the known information about source materials. The highest distance was found between the CIMMYT lines and the cluster containing the Lancaster Sure Crop related lines. The genetic distance information may be used by breeders when planning future crosses among these inbred lines.
