Collecting useful plant genetic resources at the huksan archipelago of the Korean peninsula

The exploring mission to collect wild soybean and useful plant genetic resources was carried out at the Huksan archipelago of the southwestern part of Korean peninsula during October 28 to November 3, 1990. Totally 31 plants classified into 14 families, 18 genera and 22 species were collected. Among them, 9 collected leguminosae plants including one cultivated kidney bean belonged to 4 genera and 5 species. Useful leguminosae plants collected consisted of Rhynchosia volubilis Lour, R. acuminatifolia Makino, Amphicarpaea edgeworthii var. trisperma Ohwi and Dunbaria villosa (Thunb.) Makino and 8 collected samples belonged to 3 genera and 4 species. R. volubilis Lour at Hongdo island and R. acuminatifolia Makino and D. villosa at Bigeumdo could be collected, repectively, while A. edgeworthii var. trisperma could be observed at any exploring places. It was thought that these results were due to the limitation of place and time collected. Japanese black pine, lentinus chestnut, Camellia japonica, and Machilus thunbergii had been naturally grown from place to place at the part of Huksan county. On the contrary, it has been thought that rare plants as well as wild oriental orchid, locally called “Pungnan” might be endangered and so could be hardly found anywhere to collect. More efforts and supports to conserve nature and resources at a sustainable level should be requested than ever.
