  • A new gerbera variety 'Yellow Wing' was released by the National Horticultural Research Institute (NHRI) in 2007. A cross was made between 'Gold Finger' with yellow and single and 'Yellow Springs' with yellow and spider in 2004. After investigation of the characteristics for 4 years (from 2004 to 2007), it was selected specially for the use of cut-flower. 'Yellow Wing' is a vigorous cultivar with yellow (RHS YO14B), green center and spider type. The flower diameter is 10.6cm. And inner ray floret and disc diameter is 2.83cm and 2.03cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height and brilliant color. We believe that 'Yellow Wing' has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.

  • Bud sport (bud mutation) is a valuable source for existing new genotypes in mulberry (Morus spp.) as well as critical materials for studying the molecular mechanisms underlying essential traits. Thus, identification, collection, characterization, and conservation of such natural variants are prerequisites for enhancing the mulberry genetic resource in the germplasm. In this context, we identified and characterized three bud sports (VBS-1, VBS-2, and VBS-3) of a popular mulberry cultivar, Victory-1 (V-1). These bud sports are morphologically, anatomically, and genetically more distinct from their mother plant, Victory-1. Moreover, these bud sports display lower growth and yield potential. Furthermore, these showed remarkably lower 2C DNA contents of 0.74 pg (VBS-1), 0.78 pg (VBS-2), and 0.76 pg (VBS-3), when compared to their mother plant V-1 (2C = 0.81 pg). On the other hand, molecular characterization between the bud sports and their mother plant revealed the existence of genetic variation due to the natural bud mutation that occurred in the mulberry cultivar Victory-1.

  • Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at $4^{\circ}C$. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.

  • Root and shoot development of two rice (Oryza sativa L.) cultivars with different genetic backgrounds was studied with reference to their relative growth. Tongil type (indica-japonica hybrid) cultivar 'Kuemkangbyeo' and japonica cultivar 'Koshihikari' were grown in $5000^{-1}$ a Wagnar pots under flooded condition. Three plants with roots of both cultivars were taken in every phyllochron through the heading stage to record morphological characteristics of shoot and root system. Compared to Koshihikari, Kuemkangbyeo produced more tillers and had greater shoot weight and leaf area per hill. Length and weight of the root system in both cultivars increased exponentially with time. At the same time, root system development was significantly faster in Kuemkangbyeo than in Koshihikari after the panicle initiation stage. As a result, Kuemkangbyeo has a vigorous root system which consists of larger number of nodal roots compared to Koshihikari. Also, the root length and weight per unit leaf area of Kuemkangbyeo were larger than those of Koshihikari in the later half of growing period, which suggests possible higher physiological activity of the root system of Kuemkangbyeo which is known as a high-yielding cultivar. The relationship between root traits (crown root number, total root length, and root dry weight) and shoot traits (leaf area and leaf+culm dry weight) in both cultivars closely showed allometry until the flag leaf stage.

  • 'Jaha'는 경기도농업기술원 선인장연구소에서 2006년에 육성된 적색대륜계 팔레놉시스 품종이다. 1999년에 진분홍색 꽃, 진적색 설판인 'KYP74'를 모본으로 분홍색 꽃 'KYP88'를 부본으로 하여 인공교배 후 264개의 실생묘를 얻었다. 2002년에서 2006년까지 3차례의 특성조사를 거쳐 최종적으로 'Jaha' 선발되었다. 자하는 화색이 자주색이고 설판은 적자주색인 대륜계품종이다. 꽃수는 11.0개 이상이며 화경장은 81.0로 꽃배열이 가지런하여 보기 좋다. 엽색은 녹색으로 생육속도도 빠르고 평균 꽃 수명 또한 55일 이상으로 길다.

  • 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.

  • 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.

  • 농촌진흥청 국립원예특작과학원에서는 2007년 백색 반겹꽃 'Wonder King'과 연녹빛의 백색 반겹꽃 'Ever Green'을 교배하여 얻은 실생계통으로부터 2007년부터 2010년까지 4년 동안의 생육특성검정을 거쳐 초세가 강건한 흑심의 순백색(RHS W155D) 반겹꽃 절화용 거베라 신품종 'Whiteny'를 품종육성하였다. 꽃의 직경이 11.5 cm인 대륜계통이며, 내화경과 화심장이 각각 7.8 cm와 2.2 cm이었다. 절화장은 52.2 cm로 매우 길며 꽃목의 굵기가 굵고 절화수명이 길다. 초세가 강건하고 국내 재배환경에 적합한 품종으로 재배농가의 기호도가 높아 앞으로 국내육성품종의 재배면적 확대 및 농가의 로열티 절감에 기여할 수 있을 것으로 기대된다.

  • 1999년도에 백색의 스탠다드 'Escimo' 품종을 모본으로 생육이 우수하고 다수성인 스탠다드 'Medeo' 품종을 부본으로 인공교배 하였다. 2000년에 파종을 실시하여 840개체의 실생을 획득하여 이들을 대상으로 2001~2003년까지 3차에 걸쳐 특성검정을 실시한 후 최종 특성검정 단계에서 기호도 조사를 실시한 결과 최종선발된 '원교 D1-54'를 'Honey Lemon'로 명명하였다. 'Honey Lemon'의 화색은 백색으로 RHS 칼라챠트번호 4D이며 화형은 고심형이며 향기는 거의 없었다. 꽃잎수는 17.0개로서 'Tineke'의 69.9개보다 훨씬 적었으며 화폭은 8.0 cm로 'Tineke'보다 약간 작았다. 평방미터당 연간 절화수량은 248.0본으로 'Tineke'보다 2배 이상 많았으며 절화장은 53.0 cm 절화경경은 5.0 mm로 'Tineke' 보다 길이와 굵기는 약하였으나 수량성이 높고 강건한 절화형태를 보였다. 또한 절화수명은 16.9일로 'Tineke'보다 2배 이상 길었다.
