Background : Angelica dahurica, Ligusticum sinense and Ledebouriella seseloides are cultivated in small areas in Korea. Domestic cultivation area is around 10 ha, and cultivated varieties have not been developed yet. Therefore, the quality of the product is not uniform, and industrialization is difficult. Lately, studies on the development of varieties have been carried out using domestic collecting germplasm.
Methods and Results : Germplasm was collected in Gangwon-do, Chungcheongbuk-do, Gyeongsangbuk-do, Jeollanam-do and Jeju-do and sowed in pots in March 2017. Angelica dahurica was used the collected in Gyeongsangbuk-do, Jeollanam-do, Ligusticum sinense was used the collected in Gangwon-do and Gyeongbuk-do and Ledebouriella seseloides was used the collected Jeju-do. In May of 2017, those were planted and the stem and leaf characteristics were compared and analyzed 1-year. It was bloomed in the second years of 2018, and stem, leaf and flowering characteristics were compared and analyzed. In the first year of growth characteristics, Angelica dahurica showed lower leaf and stem growth in Jeollanam-do collected germplasm. However, there was no statistical significance. Growth characteristics of Ligusticum sinense were higher in Gangwon-do collection than in Gyeongsangbuk-do, but there was no statistical significance. Ledebouriella seseloides was no significant difference between the groups in Jeju-do. In the second years, individual selection were carried out for popullation improvement. The Angelica dahurica showed green and purple stalks and the collected germplasm of Jeollanam-do showed relatively low growth. Ligusticum sinense and Ledebouriella seseloides were no significant differences in growth and color between stem and leaf, stem and stem
Conclusion : All three crops were cross pollination, and collected open pollination. Therefore, there were many segregation by germplasm and genetic variation was large. Furthermore, it is considered that statistical significance does not appear. If genetic uniformity is increased through continuous selection and population improvement, it will be possible to cultivate varieties using germplasm. Genetic variation will be a good source of genetic resources.
