To develop a new ginseng varieties with good quality and high yielding, a lot of individual ginseng plants were selected in the farmer's fields in 1972. Among them, a promising line, 7259-3-1, has been developed through comparative cultivation of several lines selected with pure line separation of local races in Korea Ginseng '||'&'||' Tobacco Research Institute. Preliminary and advanced yield trials were performed for 8 years. It was then designated as "KG 101" and tested in the regional yield and adaptation trials for 10 years (1981-1990). KG101 has a green stem with light violet and orange-yellow fruit and flowers 3-7 days later than local race, Takyungjong. Taproot of KG101 was longer than local race Jakyungjong, and root yield of KG101 was 9% higher than local race Jakyungjong. In red ginseng quality, the rates of Chun-Jeesam (Chun and Jee means 1st and 2nd grade, respectively) were 22.3% and 9.4% for KG101 and Jakyungjong, respectively. In these results, it was clarified that KG101 was superior ginseng line with good quality.y.

KG101 was developed by the Korea Ginseng & Tobacco Research Institute. We reported about yield trials and local adaptability test. Growth characteristics and red ginseng quality of KG101 in local performance test can be summarized as follows. Aerial parts growth, stem and leaf, was similar about KG101 and Jakyungjong, 4-year old and 6-year old ginseng. Emergence rate of KG101 was higher than Jakyungjong in the 3 location of local performance test. Taproot diameter of KG101 was smaller than Jakyungjong and taproot shape of KG101 had fitted characteristics, radish type and human body type, to manufactured red ginseng. Raw ginseng grade, 1st and 2nd of KG101 was higher than Jakyungjong's. Chun, Jeesam ratio to manufacture of 2nd grade of raw ginseng of KG101 was 25%, Jakyungjong was 6-13% in 3 location of local performance test. Distribution of red ginseng weight of Jakyungiong was heavier than KG101 in 2 location, Kongju and Jungup, but KG101 was heavier than Jakyungjong in Ichon. Red ginseng quality of KG101 was better than Jakyungiong. Main degrade factor of red ginseng quality was inside cavity and inside white, was not different lines and location.

To develop a new ginseng variety with good quality and high yielding, a lot of individual ginseng plant were selected in the farmers'fields in 1968. Among them, a promising line,680-83-4, has been developed through comparative cultivation of several lines selected with pure line separation from local races in KT&C Central Research Institute, preliminary and advanced yield trials were performed fir 8 years.680-83-4 was designated as KG103, which was then registered as a new variety “Gopoong” with the regional yield and adaptation trials for 10 years (1981-1990) on December 27,2000 in Korea. Gopoong has different phenotype of a dark violet stem and dark red fruit and inverted triangle shape of berries cluster as compared with other varieties. Taproot of Gopoong was longer than local race Jakyungjong, and root yield was 4.5% higher than local race Jakyungjong. In red ginseng quality, the rates of Chun-Jeesam grade(Chun and Jee means 1 st and 2nd grade, respectively) were 16.6% and 9.4% for Gopoong and Jakyungjong, respectively. In these results, it was that Gopoong was superior ginseng line with good quality far manufacture of red ginseng.
