This study was carried out to evaluate the fruit and growth characteristics of selecting Vitis amurensis through functional material analysis and sensory evaluation in V. amurensis collected in Gangwondo. For evaluation of growth characteristics in V. amurensis, experiments were carried out by compared with the two grape cultivars ’’Campbell Early’’ and ’’Kyoho’’. The full bloom and verasion time in V. amurensis was investigated faster than those of examined cultivar grapes, while harvest time was investigated latter than those of examined cultivar grapes, but agronomic characteristics was not thought significantly difference between cultivar grapes and V. amurensis. For evaluation of shoot growth phase, the growth curve was very similar to cultivar grapes. The berry size in V. amurensis showed that increases rapidly between 3 and 4 days after full bloom time, and approximately doubles between the second growth period and harvest time, and the berry development phase investigated that consist of two sigmoid growth periods separated by a lag phase. The berry weight and soluble solids in V. amurensis increased with the tree age, but acidity and total sugar contents decreased, and showed a special quality and stable growth according to vine age. To investigation of functional materials, the anthocyanin content in V. amurensis ranged from 16.6 to 50.2 mg/100 g, and the resveratrol content ranged from 0.143 to $0.236{\mu}g/100\;g$ which was higher than those of cultivar grapes. These result indicated that V. amurensis tended to have the useful material larger than cultivar grapes. Therefore, other edibility factors of V. amurensis collected in Gangwondo may contribute to breeding studies in Vitis. spp.
