  • Lipoxygenase and Kunitz trypsin inhibitor protein of mature soybean [Glycine max (L.) Merr.] seed are main anti-nutritional factors in soybean seed. A new soybean cultivar, "Gaechuck#1" with the traits of black seed coat, green cotyledon, lipoxygenase2,3 and Kunitz trypsin inhibitor protein free was developed. It was selected from the population derived the cross of "Gyeongsang#1" and C242. Plants of "Gaechuck#1" have a determinate growth habit with purple flowers, brown pubescence, black seed coat, black hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on dry weight basis have averaged 39.1% and 16.2%, respectively. It has shown resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. "Gaechuck#1" matured on 5-10 October with a plant height of 50 cm. The 100-seed weight of "Gaechuck#1" was 23.2g. Yield of "Gaechuck#1" was averaged 2.2 ton/ha from 2005 to 2007.

  • Lipoxygenase and Kunitz trypsin inhibitor protein are the main antinutritional factor in mature soybean seed. A new soybean cultivar, "Gaechuck#2" with yellow seed coat, lipoxygenase2,3-free and Kunitz trypsin inhibitor protein-free was developed.

Plants of "Gaechuck#2" have determinate growth habit with purple flowers, tawny pubescence, yellow seed coat, yellow hilum, oval leaflet shape and brown pods at maturity. Seed protein and oil content on a dry weight basis were 40.7% and 18.7%, respectively. It has shown a resistant reaction to soybean necrosis, soybean mosaic virus, Cercospora leaf spot and blight, black root rot, pod and stem blight, and soybean pod borer. Gaechuck#2 matured in 4 October with plant height of 54cm and a 100-seed weight of 24.4g. Average Yield of Gaechuck#2 was 230 - 250 kg/10a in 2005 - 2007.

  • A new spray carnation cultivar 'Leo' was released by the National Institute of Horticultural and Herbal Science in 2003. A cross was made between spray cultivar 'Ballantyne' and 'West peachy' in 1999. After investigation of the characteristics four years (from 2001 to 2003), it was finally selected in 2003. 'Leo' is a spray cultivar with light yellow color for a cut flower. The main characteristics are multi branching, long vase life and early flowering habit than 'Diamond'(control). It has medium resistance to Fusarium wilt and 9 days vase life.

  • The main characteristics of a new cultivar 'Jinhyang', a cross of a collection of monokaryotic strains of the brown button mushroom, were examined. 'Jinhyang' was not significantly different from the control cultivar 'Dahyang' in mycelial culture and cultivation period. The cap of 'Jinhyang' was thicker and darker in color than that of 'Dahyang'. The hardness and individual weight of the fruiting body of 'Jinhyang' were slightly higher than those of 'Dahyang'; however, the differences were not significant. The yield of 'Jinhyang' was 14.1 kg/m2, which was 8% higher than that of 'Dahyang'. Therefore, it is expected that it will be possible to supply this cultivar growers in the future.

  • A new spray chrysanthemum 'Pink Berry' was released by National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Korea in 2007. A cross was made in 2004 between 'Lineker Salmon', a spray cultivar with salmon petals, and 'Baeksokuk', a spray cultivar with white petals. Trials were conducted from 2005 to 2007 for evaluation and selection of this cultivar, including shade cultivation in summer and retarding cultivation in autumn. The natural flowering time of 'Pink Berry' is late October, but year-round flowering is possible by photo-periodic control. The cultivar has single type flowers with pink petals and a green flower center. It shows long vase life of 22 days and resistance to white rust. The diameter of flower is 52.0 mm. The numbers of flowers per stem and petals per flower are 15.5 and 29.5, respectively. Days to flowering under the short day treatment is about 56 in autumn seasons.

  • This study was executed to breed new cultivar of E. senticosus suitable for seed harvesting by selection method from 896 native plants collected from 35 regions. Basic selection points were C.V. values of characters such as filament length, blooming period, shoot length, no. of shoot and hundred fruits weight. By four steps of selection, two lines having high biomass yielding, diseases tolerant and fruiting capacities were finally selected and registered as new cultivar of Eleutherococcus senticosus at the Korea seed & variety service by regulation for seed production and marketing of plant variety.

  • A Hosta cultivar 'Neulpureum 1' was bred at the Korea National Arboretum, which produces new cultivars using vegetative propagation techniques. The new cultivar 'Neulpureum 1' was derived by crossing Hosta minor with Hosta 'Krossa Regal'. Among the induced leaf-color- and shape-modified hosta plants, the plants that exhibited deep-green color and small-bended leaves were selected. 'Neulpureum 1' maintained the deep-green leaves for longer than Hosta 'Krossa Regal'. Additionally, the plant height of 'Neulpureum 1' was shorter than that of Hosta 'Krossa Regal' and several leaves were observed on the new cultivar; therefore, it is likely to be used as a pot plant. The botanical characteristics were investigated for three years beginning 2012. A Hosta 'Neulpureum 1' can prove to be useful as a material for a pot plant or as ground cover plant at half-shadow place.

  • A new cultivar of Euphorbia milii, 'Panorama' was developed at Cactus Research Institute, Gyeonggi-do Agricultural Research & Extension Services in 2009. 'Gabi' and 'Maxi' were crossed in 2001 and three $F_1$ seedlings were obtained. Pedigree selection was performed in 2002. One line was finally selected and named as 'Panorama' through the test of specific character from 2007 to 2009. The new cultivar 'Panorama' has green and pink colored bract, and it has 2~3 each of inflorescence number, 2.0 cm of bract width, 4.3 each of lateral shoot and 14.9 cm of plant height. Characters of the cultivar can be maintained by vegetative propagation.

  • A new spray rose cultivar 'Cherry Tea' was bred from a cross between pink spray cultivar 'Pinocchio' and yellow spray cultivar 'Flair' at the National Institute of Horticultural Research Institute. The cross was made in 2003 and 'Cherry Tea' was finally selected in 2008 after evaluating characteristics for three years from 2006 to 2008. 'Cherry Tea', a light orange spray cultivar grows vigorously and has good vase life. The major characteristics of this cultivar are $137stems/m^2/year$ in yield, 68.8 cm in length of cut flower, 5.5 cm in flower diameter, 34.0 in petal number, and 12.4 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference of this cultivar is relatively higher than that of control cultivar, 'Little Marble'.
