Tamra' was selected in Jeju in 1997 and its open-pollinated progenies were proliferated at the Korea Forest Research Institute in Suwon, Kyungkido. Stability of genetic characteristics was evaluated from 2001 to 2004. The progenies were annually managed with transplanting and 5 to 6 times in weeding. Leaves, flowers, branches and growth characteristics on selected trees were investigated. Results of morphological characteristics showed that 'Tamra' has simple flower in open type of flower and funnel shape in flower type. It has flower diameter of 100.0 mm that is relatively very large as compared with contrastive cultivar, 'Chilbo'. The petal is slightly folded as compared with contrastive cultivar and its eye zone is not spread. Leaf type is in oval shape, and leaf length and width are short (47.1 mm) and narrow (23.8 mm), respectively. Leaf width to width of leaf shoulder ratio having 1.5 is much wider as compared with contrastive cultivar having 1.4. Thickness of leaf, gloss of leaf and density of branch are all medium. Quantity of bloom is in normal condition and changes in the number of flowers by seasons are small, also, its blossom comes into summer. 'Tamra' having large flowers and red color could be useful for a good ornamental and garden tree.

A new variety 'Suni' was released from the cross between 'Ujeong' and 'Asadal' by the breeding laboratory of the Korea Forest Research Institute (KFRI) in 2001, and the preliminary, advanced and regional trials for evaluation and selection of this variety, were carried out from 1997 to 2001. The progenies were annually managed with transplanting and 5 to 6 times in weeding. Leaves, flowers, branches and growth characteristics on selected trees were investigated. Results of morphological characteristics showed that 'Suni' has simple flower in open type of flower and funnel shape in flower type. The diameter of flower is 61.9 mm and very small as compared with contrastive cultivar, 'Yeongkwang'. The petal is fully folded as compared with contrastive cultivar and diameter of eye zone is 19.7 mm. Leaf type is in oval shape, and leaf length and width are short (58.3 mm) and narrow (34.4 mm), respectively. Leaf width to width of leaf shoulder ratio having 1.7 is very wider as compared with contrastive cultivar having 1.4. Shape of leaf margin, depth of leaf margin and shape of base of the variety are serrate, medium and rounded, respectively. Quantity of bloom is in normal condition and changes in the number of flowers by seasons are small, also, its blossom comes into summer. 'Suni' having very small flowers could be useful for a good ornament as a dwarf variety.

To investigate and compare the variety of different flowers used in a painting of flowers and birds of Japan and Korea, the relevant Japanese era to Joseon Dynasty where traditional folk art revitalized was studied. This study aims to deliver a through and prescriptive approach to the research in question through horticulturalistic and color-orientated approach as well as the standard format of research and development. Through this study Japanese paintings were shown to prefer peony at best and other flowers such as Japanese apricot, Chrysanthemum, Bamboo, Japanese red pine were also popular which is similar to those of the Joseon period. However in Joseon dynasty, peony seized 17% of all flowers used in Folk-Art paintings unlike 10% in Japanese paintings. Whatsmore 10 of 20 most favoured plants of Joseon dynasty were shown to be shrubs whilst it was 6 for Japan illustrating flowering plants were more popular. The study of range showed paintings of Joseon dynasty using 85 varieties whilst Japanese paintings using 82 varieties hence again showing similarity. Moreover Joseon paintings illustrated that they used mostly wild flowers whilst Japanese paintings depicted more imported flowers such, Pyracantha, Gladiolus, Carnation In terms of identification of flower in the paintings, Japanese practiced precise painting technique making it easy to identify unlike the Joseon paintings where more abstract techniques of folk-Art producing difficulties in classification.

Encouraging progress in the mutation breeding has been achieved since a mutation induction has become increasingly important for a cultivar development for complex reproductive or propagating modes, the creation of new genetic resources, especially for crops with a narrow genetic base, and the use of mutants for a genomics study. In Korea, more than 35 cultivars have been released by using the mutation breeding method since the mid-1960s, and the released cultivars were mostly developed (76%) by exposing to radiations (gamma and/or X-ray). Most of the released mutant cultivars (74%) in Korea were food and oil seed crops, especially for improving agronomic traits such as yield, lodging tolerance, maturity, or functional compounds. Currently a high yield potential of cultivated crop cultivars is relatively less popular than before, but the expectation of value-added crops, from the farmer’s side, is in high demand. Accordingly, the mutation breeding program in Korea has assigned more resources to other crop species, including some flowering and ornamental plants. These flowering and ornamental plants are ideal systems for a mutation breeding because their favored traits such as flower color or shape or plant architecture can be visually monitored after a mutagenic treatment. Additionally, these plant species are genetically heterozygous and often propagated vegetatively, which allows for an isolation and selection of mutants within M1 generation. In Korea, a program for the development of potential cultivars of flowering and ornamental crops was launched with financial support from the Biogreen 21 project in RDA. Thisintegrated program which will be conducted by a diverse array of experts will focus on major flowering and ornamental crops in Korea such as rose, chrysanthemum, lily, carnation, orchids, and clover. The potential outcomes from the program will be new highly valued-added cultivars which will provide greater money gains to Korean farmers and lots of valued mutants used for a gene isolation of interest and reverse genetics or functional genomics. Appropriate strategies should be implemented to complete its goals successfully, which includes a)induction of a wide mutant spectrum, b)applications of new irradiation techniques, c)unraveling the complex genetic phenomena controlling mutant traits, and d)development of a mass production and an intensive export system for the developed cultivars.

본 연구는 대학교의 원예 비전공 일반 학생들을 대상으로 한 교양과목인 생활원예 수강자를 대상으로 화훼식물에 대한 인지도 현황을 알아보기 위하여 수행되었다. 주변에서 흔히 화훼식물로 이용하고 있는 초본화훼류 52가지와 관엽식물 20가지, 화목류 18가지, 야생화 10가지를 포함한 총 100가지 식물을 LCD 프로젝터로 보여주고 각 식물에 대한 일반 정보를 구두로 전달한 뒤 식물명을 응답자가 기록하였다. 조사된 초본화훼류 52종 중에서 응답자들은 평균적으로 13.2% 만을 식별하여 식물명을 기록하였다. 대부분이 도입식물인 관엽식물의 경우에는 실내 생활 속에서 가장 흔히 볼 수 있음에도 불구하고 2.8%라는 가장 낮은 인지도를 보였다. 주로 자생하는 식물류인 화목류와 야생화의 경우 화목류의 인지도는 38.6%로 매우 높았으나, 야생화는 11.5%로 낮은 인지도를 나타냈다. 성별에 있어서 여성 응답자의 인지도는 18.0%로 남성 응답자의 13.2%보다 높았다. 비도시지역 출신의 응답자는 도시나 대도시 출신 응답자보다 인지도가 높았다. 결론적으로 응답자의 화훼식물에 대한 전체 평균 인지도는 15.5%로 매우 낮아, 교양과목으로서 생활원예는 무엇보다도 화훼식물명에 대한 학습이 선행되어야 할 것으로 판단된다.

한국의 화훼산업은 1980년도부터 화훼류의 국내소비가 급증하게 되었고 그 수요를 충족시키기 위하여 화훼산업이 급진적으로 발전하였던 것은 사실이다. 그러나 농산물의 세계화에 따른 국내 생산의 차별화가 요구되는 시기이다. 따라서 생산적인 측면보다는 소비촉진에 관련한 연구가 매우 긴요한 시기일 것이다. 본 연구는 한국의 화훼소비 중에 잠재적 수요라 할 수 있는 일반수요의 촉진을 위해 결혼한 성인을 대상으로 그들의 소비형태 와 이용 동기에 기초 자료를 제공코자 하였다. 그 결과를 요약하면 다음과 같다. 첫째, 여성이 남성에게 가장 주고 싶은 선물은 꽃(41%)으로 가장 높았고, 여성에 있어서 자녀로부터 받고 싶은 선물은 37%로 꽃 선물이 가장 높았다. 둘째, 성인이 선호하는 화훼류는 전체적으로 난류(33.6%)>분화(25.1%)>분재(16.4%) 순으로, 여성은 남성과 달리 분화(32.5%)에 대한 선호도가 높았다. 그리고 화훼용도에서는 자가 장식용(66.7%)으로 구매하는 특성을 보였으며, 여성에 있어서는 더욱 현저하였다. 셋째, 성인의 선호 화훼류 형태는 난분(41.0%)>꽃다발(32.6%)>꽃바구니(22.3%)>꽃꽂이(3.0%) 순이고, 꽃선물 1회 비용에 있어서는 전체적으로 2만원(40.4%)을 사용하고, 여성은 남성에 비해 다소 높았다. 넷째, 성인의 이용동기에 있어 식물도입의 이유는 정서적(49.4%)>미적(38.4%)>공학적(8.2%)>건축적(2.8%) 순으로, 남성은 정서적(52.7%)에 대한 식물 도입의 동기가 가장 높았다. 또한 식물 도입이 아동에 미치는 영향은 정서적>미적>화목적>위생적>육체적 순으로 그 효과에 관하여 인식하고, 가정원예의 즐거움은 전반적으로 미감적>화목적>오락적>경제적ž위생적 순으로 인식하고 있었다. 성인의 화훼류 이용 동기에 관하여 요인분석은 효능 기능적 동기, 자기 지향적 동기, 타인 지향적 동기 그리고 사회적 상호적 동기로 4개의 집단으로 구별됨을 알 수 있었다. 결론적으로 화훼시장 정보의 중요성을 인식하면서 보다 계층적이나 연령적으로 세분하여 더 많은 연구가 필요할 것으로 생각된다.

The backcross population obtained from a reciprocal cross between PD7 (A. inodora × 수식 이미지 A. psittacina) and P002 (A. inodora) was used for the QTL analysis. A total of 122 individual BC₁ 수식 이미지 plants were scored for 12 traits and interval ma
