The study on vascular plants of Gayasan National Park was conducted in 2016 over a period of 34 days from March to October 2016. As the study, a total of 768 taxa were recorded, including 118 families, 396 genera, 691 species, 15 subspecies, 51 varieties, and 11 forms. In the vascular plants, four endangered wild plants were recorded, Ponerorchis cucullata (L.) X.H.Jin, Trientalis europaea var. arctica (Fisch.) Ledeb., Cypripedium macranthos Sw., and Pedicularis hallaisanensis Hurus. Taxa of Least Concern (LC) or higher level on National Red List published by the Ministry of Environment of Korea were 21 taxa for example Tricyrtis macropoda Miq., and Lilium cernuum Kom. A total of 37 Korean endemic plants were investigated for example Abies koreana E.H.Wilson and Impatiens atrosanguinea (Nakai) B.U.Oh & Y.P.Hong. A total of 162 taxa of floristic regional indicators (3rd to 5th degree) were investigated including 9 taxa of V, 15 taxa of IV, 38 taxa of III, 45 taxa of II, and 53 taxa of I. Naturalized plants were recorded a total of 46 taxa with a Naturalization Index of 6.0%, the Urbanization Index was calculated to be 14.3% and 5 taxa of ecosystem disturbance plants were investigated such as Sicyos angulatus L., Rumex acetosella L., and Humulus scandens (Lour.) Merr. As the result of comparison with previous studies, in this study a total of 206 taxa were newly identified including 62 families, 144 genera, 184 species, 2 subspecies, 15 varieties, and 5 forms.

In order to provide fundamental information about the floristic composition of the area along with an assessment of the environmental impact, a floristic study of the vascular plants in the Tamjin River estuary in Gangjin-gun was conducted for a total of nine days, in the period from June 2014 to September 2014. We found that the vascular plants in this region comprised 424 taxa belong to 102 families, 281 genera, 390 species, 5 subspecies, 26 varieties, and 3 forma. Five taxa of Korean endemic plants including Weigela subsessilis (Nakai) L.H.Bailey, Lespedeza maximowiczii var. tricolor (Nakai) Nakai, and Clematis trichotoma Nakai were collected. Two least concern (LC) taxa of rare plants (as designated by the Korea Forest Service) were collected: Hydrocharis dubia (Blume) Backer and Platycladus orientalis (L.) Franco. Ten the floristic regional indicator taxa from the third to the fifth grade were identified: two taxa belonged to grade IV, and eight taxa belonged to grade III. Twenty-four taxa of salt-tolerant plants, including Artemisia fukudo Makino, Carex rugulosa Kuk., and Suaeda glauca (Bunge) Bunge, as well as 44 taxa of aquatic plants, including Najas marina L., Nuphar oguraensis Miki, and Nymphoides indica (L.) Kuntze, were investigated in this region. Fifty-nine taxa of naturalized plants were recorded, among which the following six taxa were plants that caused ecosystem disturbance: Ambrosia artemisiifolia L., Humulus scandens (Lour.) Merr., Lactuca scariola L., Rumex acetosella L., Solidago altissima L., and Symphyotrichum pilosum (Willd.) G.L.Nesom.

Breeders typically use core collections of a specific trait or core collections selected by a few genotypes to efficiently select breeding materials or to study functional genes. As a result, many accessions have been deemed redundant or duplicated and are no longer considered for use. This study aimed to investigate the agronomical characteristics and genetic diversity of 1,514 previously unused and unstudied wheat germplasms and to confirm their value as breeding materials using population structure analysis. The performance of these wheat germplasms was compared with that of 8,878 wheat breeding materials and 72 known Korean wheat cultivars. The results of agronomic trait diversity comparison showed that the germplasm populations used for breeding research did not completely encompass the unused germplasm populations. The agronomic traits of wheat germplasms varied greatly. ANOVA and PCA results revealed the greatest differences in growth habits (CV=0.339), panicle length (CV=0.330), and awn length (CV=0.296). To accurately assess the value of unused wheat germplasms as breeding materials, 106 SSR markers were extracted from the analysis of four representative Korean cultivars: Geuru, Geumgang, Uri, and Jokyoung. Among these, 24 SSR markers were chosen, and 129 wheat resources were subjected to population structure analysis, which revealed five subpopulations. Most of the 34 germplasms that originated in Korea were distributed in subpopulation 1 (18 accessions, 52.9%) and subpopulation 4 (12 accessions, 35.3%). Subgroups 2, 3, and 5 differed significantly in agronomic traits and genotypes, indicating their potential as breeding materials. The findings of this study could serve as a foundation for breeders and aid in the discovery and utilization of new wheat breeding materials.
