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, 680-98-2, has been developed through comparative cultivation of several lines selected with pure line separation from local races in Korea Ginseng & Tobacco Research Institute. Preliminary and advanced yield trials were performed for 8 years. 1) One of them was designated as KG102 and it was then registered as a new variety "Yunpoong" with the regional yield and adaptation trials for 10 years (1981-1990) on November 30, 1998 in Korea.2) For the root characters, the diameter of taproot and ratio of the taproot length to the diameter of Yunpoong were bigger and lower than those of Jakyungiong. Root yield was 27.3% higher in Yunpoong than Jakyungiong.

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.

This paper reports the characteristics of 8 new cultivars for selected from Korean ginseng. The occurance of multi stems were the highest in Yunpoong(45%) and the lowest in Gumpoong(7%), but growth of aerial parts were the highest in Gumpoong and the lowest In Yunpoong among new cultiyars. The ratio of seeds harvest were the highest in Gumpoong(85.4%) and the lowest in Chunpoong(69.1%), but number of seeds per plant were the highest in Yunpoong(108.3ea) and the lowest in Chunpoong(77.5ea) among new cultivars. The ratio of leaf burning were the highest in Chunpoong but the lowest in Yunpoong among new cultivars. In weight distribution of the different parts of the ginseng roots, the ratio of main root were high in Jakyungjong(63.1%) but low in new cultivars(49%-55.9%), but the ratio of lateral root were high in new cultivars(19.3-23.3%), but low in Jakyungjong(13.2%), the ratio of fine root were not different. Root yield declined in the order of Yunpoong, Gumpoong, Gopoong, Chunpoong, Sunpoong, Jakyungjong. The length of main root were the longest in Chunpoong(8,0cm) but the shortest in Yunpoong(6,4cm), The ratio of rusty-root was low in new cultivars(0,2-9,5%), but high in Jakyungiong(16,3%). The grade of red ginseng roots decreased in the order of Chunpoong, Gumpoong, Gopoong, Sunpoong, Yunpoong, Cheongsun, Jakyungjong. The total ginsenoside contents per dry weight in main roots was high in Gumpoong(8.53mg), Yunpoong(8.13mg), Gopoong(7,47mg), but low in Chunpoong(5.73mg), Sunpoong(4.87mg).
