| Outline of Final Research Achievements |
Larix gmelinii var. japonica is one of the major introduced coniferous species in Hokkaido, Japan, although the genetic origin of this species remains unknown. We searched for the origin and history of the specific families of Larix gmelinii var. japonica that were used in breeding programs, and evaluated the phylogenetic lineage.
This study successfully made the catalog of Larix gmelinii var. japonica that contained information of genetic resources for all of the breeding families and determined the draft chloroplast genome of this species. The cpDNA-wide comparisons among species and among Larix genus also found that the two genetic lineages were not consistent with the previously assumed lineages, and the proportion of the families was uneven among lineages. These insights would be informative for future breeding programs of L. gmelinii.
