Abstract
For the purpose of classification in Vitis spp. including wild species, according to external characters of the official standard, multivariate analysis was examined.
Grading was done for 20 spp. with 167 characters through 6 years. These data were examined with their means of years, standard error, and inner corelation, and 56 characters were reserved for the analysis.
Then, cultivars were classified into 25 clusters by with 23 connected characters.
At last, characters were devided 4 parts (total, leaf and shoot, fruit, ripe twig), and cultivars were analysed by "quantification analysis No. 4 and No. 3", applying each cluster to a category, and distance of each cultivar was supposed by 2-dimension plate.
By this method, Vitis species (V. amurensis; V coignetiae; V vinifera) can be classified clearly. 'Shiraga-budou' was appreciated the different species from V. amurensis. Classification of varieties can be done by use of "quantification analysis No. 3", but sometimes it was indistinct by much dispersion of their spots on the plate.
