Identification of Gaeryangmeoru (Vitis sp.)’s Origin Using Isozyme Analysis

초록

This study was conducted to infer the origin of Gaeryangmeoru (Vitis sp.) which has been known as the progeny obtained by crossing V. flexuora and ‘Concord’. As the result of isozyme analysis, the Gpi-2 genotype of V. flexuosa known as the female parent of Gaeryangmeoru, was “gh”, and that of ‘Concord’ known as the male parent of Gaeryangmeoru, was “ij”; however, the Gpi-2 genotype of Gaeryangmeoru was “bd”. The Pmg-2 genotype of V. flexuosa was “cc”, and that of ‘Concord’ was “hh”; however, the genotype of Gaeryangmeoru was “bf”. In our study, genotype of Gaeryangmeoru did not include genotypes of V. flexuora and ‘Concord’ and had the genotypes of European and American Hybrid Group. Therefore, we could infer that the origin of Gaeryangmeoru might be a seedling by a crossing between the species of the European and American Hybrid Group, an imported species bred by a crossing between the European Group and the European and the American Group, or a hybrid between them.
