Grapevine is one of the most important horticulture crops in the world as well as in Iran. Some cultivars have been cultivated for thousands years in different parts of Iran. Some intra-cultivar mutations may be created during these long time periods. Identification of intra-cultivar clones has important role in grapevine breeding. Some of these clones have agronomically important traits. The present study was designed to identify intra-cultivar genetic diversity using SSR marker within a group of 42 accession of "Askari", 34 accession of "bidane sefid", 21 accession of "bidane ghermez" and 10 accession of "khalili" collected from different parts of Iran. Recognition of genetic diversity between accessions of each cultivar was carried out using 14 SSR markers. Six accession (3, 21, 31, 44, 46 and 114) of Askari were different from 36 remaining accession. Accession no. 46 was identical with accession 114. Forty-two access of Askari divided into six clones, five clones with genetic differences and one clone (36 identical accession) without genetic differences. In Bidane Sefid, accessions no, 51, 56, 64, 70, 80, 96, 103 and 33 were different from 26 identical accessions. Accession 51 (identical with accession no. 70) was one clone. Also, accession 56 (identical with 96 and 33) was one clone. So, 34 accession of Bidane Sefid were six clones. Five clones with genetic differences and one clone (26 identical accessions) without genetic differences. In Bidane Germez, accession 57, 66, 76, 79, 81, 83, 84 and 92 were different from 13 identical accessions. Accession 57 (identical with 79 and 81 ) was one clone and other five genetically different accession were five different clones. Twenty one accessions of Bidane Ghermez were seven clones. Six clones with genetic differences and one clon ( 13 identical accession) without genetic differences. In Khalili, accession 6, 8, 15, and 27 were different from remaining accession (six identical accession) without genetic differences.
