This study was carried to survey distribution of the nucleotide polymorphisms in heme-binding (HB) domain, which is highly conserved region between 1,210 and 1,240 bp of cytochrome P450, in domestic garlic cultivars. 120 garlic cultivars collected from Korea were classified into seven HB domain variation based on the nucleotide sequence of the domain. Northern type garlic cultivars, collected from Kyungpook, Chungnam, Chungpook and Kangwon province, showed 51.3% of KP2 type nucleotide sequence, 5'-TTT/GGC/GGT/GGA/CGG/AGA/ATA/TGT/CCT/GGA-3' with coding amino acid FGGGRRICPG, 13.7% of KP1, 11.3% of CP, 8.8% of CM and 5% of KW2 types. Southern type cultivars, collected from Kyungnam province, showed 52.5% of KM type nucleotide sequence, 5'-TTT/GGC/GCA/GGA/ CGG/AGA/ATT/TGT/CCT/GGA-3' with coding amino acid FGAGRRICPG, 22.5% of KP2, 5.0% of KW2 and 2,5% of CP type nucleotide sequence. These results showed that Korean garlics were cultivated in highly mixed condition even in the same region.
