Abstract

Genetic variations of Semisulcospjra gottschei in Korea were investigated by means of starch gel-electrophoresis. The results are as follows; 1) Eight loci of <TEX>${\alpha}$</TEX>-Gpd, Mdh-2, Pept-1, Pgm-2, Gp-1, Gp-2, Gp-3 and Gp-4 were monomorphic, and 8 loci of Mpi, Mdh-1, Pgi, Got, Pept-2, Pept-3, Pgm-1 and Sdh showed genetic variations. 2) Means of allele per locus (<TEX>$\bar{A}$</TEX>) and polymorphism (P) were revealed 0.64 and 0.44, respectively. The value of heterozygosity (<TEX>$H_G$</TEX>) showed a little more than heterozygosity <TEX>$H_D$</TEX>. (<TEX>$H_D$</TEX>=0.09, <TEX>$H_G$</TEX>=0.13) 3) Genetic variation appears to be due to loci of Got, Pept, Pgi, and Sdh, all of which of the <TEX>$H_D$</TEX> values are high.
