Abstract
Allozyme variation was examined in three diploid taxaChionographis japonica var.japonica, var.kurokamiana, andC. koidzumiana and three tetraploid taxaC. japonica var.kurohimensis, ssp.hisauchiana, and ssp.minoensis. Results show thatC. japonica var.kurokamiana is genetically closer toC. koidzumiana than to var.japonica. In the tetraploid taxa, fixed heterozygosities were found at several loci, and this supports the hypothesis that these taxa are allotetraploids. Furthermore, the tetraploid taxa have many unique alleles not found in the diploid taxa. This suggests that sufficient time has passed since the origin of tetraploids for new mutations to have been fixed.
