The New bicolor spray rose (Rose hybrida Hort.) cultivar was developed by line selection in 2000 at the Flower Breeding Research Institute, Gyeongnam ARES. Characteristics were investigated three times from 2003 to 2006. 'Yellow King' was crossed between 'Spring Time' and 'Flair' and it has a Yellow Orange-group color (RHS No. 16A), few thorns and spray flower with a good harmony between ray floret and flower center. The vase life of cut flower was 9.1days. It was registered as commercial cultivar in 2006. This new cultivar could be planted in most of greenhouse production region of Korea and will be released to general rose growers in 2007.

경남농업기술원 화훼육종연구소에서 2000년부터 교배조합 육성을 위하여 국내의 재배농가와 종묘업체로부터 유전자원을 수집한 후, 2000년부터 2007년에 걸쳐 교배 및 계통선발육종을 하였다. 2004년부터 2006년까지 3회의 특성검정을 거쳐서 호접란 신품종 '리틀 듀'를 개발하였다. '리틀 듀'는 백색 미니 다화성계 품종으로 꽃잎, 꽃받침, 설판이 모두 백색이며 꽃 크기는 3~4cm 정도이다. 특히 화경이 3~4개 정도가 발생하여 많은 꽃이 피고 꽃배열도 우수하여 관상가치가 높아 시장성이 우수하다고 판단되었다. 또한 조직배양을 통해 영양번식도 용이한 것으로 나타났고 재배가 용이하고 생육속도도 매우 빠른 것으로 나타났다. 꽃수명도 긴 편이며 병충해 발생도 적고 저온처리를 통한 개화조절도 용이하여 상업용 재배에 적합한 품종으로 판단되었다.

"Hyehwa" an Asiatic lily cultivar was released in 1998 at National Institute of Horticultural and Herbal Science (RDA), Suwon, Korea. The cross was made in 1991 between Asiatic lily "White Bird", a white colored, and "Avignon", an unspotted scarlet red colored. It was preliminarily selected as A93-20 in 1993. Its multiplication, bulbing growth and flowering characteristic tests were conducted from 1994 to 1998. A new cultivar "Hyehwa" flowers in middle of June and grows 98.7 cm in height. Flowers bloom upward-facing, thick orange (RHS, 28A). Year-round flowering is possible by storage of the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease control is needed in the wet season.

A new gerbera variety "Pink Swan" was released by the National Horticultural Research Institute (NHRI) in 2007. A cross was made between "Royal" with orange and single and 'Himalaya' with white and semi-double in 2004. After investigation of the characteristics for 4 years (from 2004 to 2007), it was selected specially for the use of cut-flower. "Pink Swan" is a vigorous medium-sized cultivar with pink (RHS R48D), yellow green center and semi-double. The average flower diameter is 10.6 cm. And inner ray floret and disc diameter is 5.99cm and 1.83cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height. We believe that "Pink Swan" has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.

A new spray chrysanthemum cultivar, 'Moon Festival' was released by National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Korea in 2007. A cross was made in 2002 between '01B1-559', a breeding line of NHRI and 'Baeksokuk', a spray cultivar with white petals. Trials were conducted from 2005 to 2007 for evaluation and selection of this cultivar, including shading culture in summer and retarding culture in autumn. The natural flowering time of "Moon Festival" is late October, but year-round flowering is possible by shading and lighting treatment. The cultivar is semi- double type flowers with light-ivory white petals and green flower center. Flower neck and stem are very hardy. The diameter of flower is 67.5 mm. The number of flowers per stem and petals per flower is 11.5 and 100.5, respectively. The days to flowering under the short day is about 54 in autumn season.

The rapid growth of world population, reduction of cultivated areas for crop production, and detrimental effects of pests, diseases, and climate changes have required to breed new rice cultivars with high yield, accepted quality, but strong resistance to abiotic and biotic stresses. However, traditional breeding needs much time to breed a new cultivar, whereas the successful use of molecular breeding is still questionable. We have developed a novel mutation which allow to cross many rice cultivars together with low segregation, that allow to breed a new cultivar in only several cropping. The mechanism has been unknown, but we suggest that gene linkage may play a crucial role, of which the semi dwarf gene might be the center gene for gene linkage occurrence. The phenomenon of this possible gene linkage is contrary to Mendel rules, but it is promising to breed new rice cultivars, of which, the most elite genes in rice might be able to gather in a targeted rice variety.
