Background : Recently, there is a urgent demand for development of new varieties with enhanced resistance to various biotic/abiotic stresses. In order to develop ginseng varieties with such traits, systematic breeding program and comprehensive field studies are prerequisite. Methods and Results : ‘Cheonmyeong' seeds were collected in 2008 from the farmer field of Buyeo. Physiological investigation and propagation were conducted from 2009 to 2011. It was given the name 'Eumseong No. 8 through the observed yield trial from 2012 to 2013 and local adaptability was carried out from 2014 to 2015. All phenotypes including agronomic characteristics, seed yield, and physiological response to biotic/abiotic stresses were investigated according to the ginseng GAP and UPOV guidelines. Yellow-red leaf and pink berry at maturing stage were observed. The time of emergence, flowering and berry maturity of the ‘Cheonmyeong’ were faster than those of ‘Chunpoong’. Stem length of ‘Cheonmyeong’ was shorter than that of ‘Chunpoong’, whereas stem diameter was thicker than that of ‘Chunpoong’. Main root length was shorter but main root diameter is thicker than that of ‘Chunpoong’. Number of seeds of ‘Cheonmyeong’ was fewer than that of ‘Chunpoong’ but 1,000-seeds weight and stratification rate were higher than those of ‘Chunpoong’. The yield performance of this variety was 661 kg/10 a in local adaptability test for two years, which is 22% higher than that of ‘Chunpoong’. ‘Cheonmyeong’ showed strong resistance to phytophthora blight, mulberry mealybug and nematode and moderate resistance to alternaria blight. ‘Cheonmyeong’ did almost not occur yellow spot of aerial part and rusty skin of root, show moderate resistance at high temperatures. Conclusion : Our study demonstrated that ‘Cheonmyeong’ is an ideal variety with heavier root weight and enhanced stress resistance and contribute will enhance biotic/abiotic stress resistance and increase the farmers' income.

“Greenstar”, a new Saxifraga cultivar was bred by crossing between “Geumgongjak” with green (YG145C) petals and “Rokseon” with red purple (RP62A) petals in 2003. The selection and flower characterization were conducted from 2003 to 2006 in greenhouses of the National Institute of Highland Agriculture. The flowering of “Greenstar” starts on September 17 for 36 days and the number of flowers per plant was about 290. The flower color is a green (G142C) and the number of petals was 5. Flower width is 2.1 cm and flower length is 1.9 cm. “Greenstar” can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occur usually by over-irrigation.

The selection and flower characterization were conducted from 2004 to 2006 in greenhouse of the National Institute of Highland Agriculture. The flowering of “Snowmaple” starts on October 9 for 16 days, The number of flowers per plant was 315 with strong concurrent flowering habit. The flower shows red purple (RP62C) at opening, but It turns gradually changable from red purple to white. The flower has 5 petals, and the size is 2.0 cm in width and 2.3 cm in length. “Snowmaple” can be used for pot flower. Fifty percent shading is a good cultural practice against direct sunlight and soft rot disease would occurs usually by over-irrigation.

“Harmony”, a new Saxifraga cultivar was released by the National Institute of Highland Agriculture (NIHA), in 2006. A crossing was made between “Hongsaja” with red purple (RPN66A) petals and “Yangwoo” with red-purple (RP61C) petals in 2004. The selection and flower characteristics were investigated from 2004 to 2006 in greenhouse. The first flowering time of “Harmony” is 28th of September, period of flowering is 29 days and number of flowers per plant was 224.1. The flower color shows a red purple (RPN66A) and number of petals was 11.0. Flower width is 1.8 cm and flower length is 1.4 cm. It can be used for pot flower. 50% shading treatment is a good cultural practice against direct sunlight and soft rot disease occurs usually by over-irrigation.

“Piangse”, a new Saxifraga cultivar was released by the National Institute of Highland Agriculture (NIHA), in 2006. A crossing was made between “Jeokhoamugab” with red purple (RP68B) petals and “Okchung” with red-purple (RP62A) petals in 2004. The selection and flower characteristics were investigated from 2004 to 2006 in greenhouse. The first flowering time of “Piangse” is 25th of September, period of flowering is 25 days and number of flowers per plant was 98.1. The flower color shows a white (W155C) and number of petals was 7.0. Flower width is 3.6 cm and flower length is 2.9 cm. It can be used for pot flower. 50% shading treatment is a good cultural practice against direct sunlight and soft rot disease occurs usually by over-irrigation.

“Festival”, a new Saxifraga cultivar was released by the National Institute of Highland Agriculture (NIHA), in 2006. A crossing was made between “Bulzihoa” with red purple (RPN57C) petals and “Hongkyo” with red purple (RPN57C) petals in 2002. The selection and flower characteristics of “Festival” were investigated from 2003 to 2006 in greenhouse. The first flowering time of “Festival” is 19th of September, period of flowering is 36 days and number of flowers per plant was 119.9.
