Using polyacrylamide vertical slab-gel electrophoresis, 14 cutting cultivars of the Obi-sugi group, one cultivar each of Yabukuguri and Measa, and others of sugi (Cryptomeria japonica D.DON) were analyzed for the compositions of their clonal mixtures. The genotypes of 76 individuals, including plus trees of these cultivars, collected as breeding stocks at the Forestry and Forest Products Research Institute and the Kyushu Forest Tree Breeding Institute, were determined based on nine isozyme loci. The number of individuals within each cultivar analyzed ranged from one to nine. Five loci out of nine : namely, 6Pg-2,Got-2,Gdh, Pgm-1,and Pgm-2,were common, and only four loci : namely, Got-1,Lap, 6Pg-1,and Dia-3,were polymorphic. Clone analyses were made for cultivars which had more than two individuals, and 11 cultivars of the Obi-sugi group, Yabukuguri, and Measa were found to be composed of at least two to five clones.
