임기병,김홍열,박노은,손병구,안형근 한국육종학회 2016 한국육종학회지 Vol.48 No.4

A new Phalaenopsis cultivar Hwasu 3551 was bred by Kyungpook National University, Korea, which produces young plants through tissue culture techniques. The new cultivar Hwasu 3551, showing the phenotype of pink colored large stripe type characteristics, was derived from crossing between Phalaenopsis Minho Princess and Minho Stripes. An elite individual number '03-35-51' later coined as 'Hwasu 3551' was selected among about 300 individual progenies for more than 2 years intensive selection process covering vegetative and flowering distinctiveness. In year 2006-2007, the 1st and 2nd characteristic analysis were carried out through performance and uniformity test. The Hwasu 3551 shows that flower color is bright clean pink (RHS#RP69D) and flower shape is formal type with size of 7.4 and 8.8cm in flower length and width, respectively. Hwasu 3551 is regarded as raceme flower type suitable large flower pot market. The leaf of Hwasu 3551 is rowing horizontally and about 22.3cm in length and 9.4cm in width, respectively. This cultivar also possesses no genetic variation, fast invitro propagation and easy growing due to vigorous growth habit. This Hwasu 3551 is registered (Reg.#:2917) to Korea Seed & Variety Service (KSVS) in 1st December, 2009 and PBR (plant breeder's right) is currently controlled by Sangmiwon Orchid Company, Korea.

임기병,하우미,심경구 한국원예학회 2015 원예과학기술지 Vol.33 No.3

A new Hibiscus cultivar ‘Daewangchun’, having vigorous growth, uniform plant habit, upright, compact branches, and a long red eye was developed through interspecific crosses between H. syriacus ‘Samchully’ (♀) and H. sinosyriacus ‘Seobong’ (♂). The Hibiscus breeding program was initiated in 2005 and Hibiscus × Daewangchun’ as preliminarily selected as ‘05-R-204’ in 2 008 due to i ts v igorous growth a nd s table flower q uality w ith rich pink flowers. The selected line w as further e valuated for different growth characteristics, leaf shape, leaf size, and flowering characteristics, as well as tested for distinctness, homogeneity, and stability during 2010-2012. The new cultivar ‘Daewangchun’ had violet pink flowers (RHS N80C) with a long red eye spot, medium size and fan petals. The size of flower was 12.0 cm and size of the red eye was 3.0 cm. Leaves were 8.7 cm long and 4.7 cm wide. After plant characteristic evaluation for 3 years (2010-2012), 05-R-204 was registered as cultivar ‘Daewangchun’ (4731, No. of plant variety protection rights) in 2013. This newly developed cultivar ‘Daewangchun’ has tall vigorous growth and unique flowers with a long red eye and can be used as specimen plants in landscaping.

Influence of Genotype, Explant Source, and Gelling Agent on in Vitro Shoot Regeneration of Chrysanthemum

임기병,권수진,이수인,황윤정,Aung Htay Naing 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.4

The capacity for shoot regeneration of leaf, petiole, and stem explants of eleven chrysanthemum cultivars was examined on the MS medium containing 1 μM naphthaleneacetic acid and 10 μM 6-benzyladenine solidified with 0.8% Agar, 0.4% Agarose, or 0.25% Gelrite. Significant differences in frequency of callus formation and regeneration from the different explants were observed among the different cultivars when grown on the media solidified with the different gelling agents. Gelrite was found to be the most effective gelling agent in promoting of the shoot. Of the different explants used, in general, stem exhibited the highest frequencies of shoot organogenesis and mean number of shoots per explant regardless of cultivar and gelling agent. However, the highest frequency of regeneration (11.67shoots per explant) was noted from leaf explants of cv. Borami followed by (4.33 shoots per explant) from stem explants of cv. Yes Nuri. Shoots were directly developed from the surface of explants, not through callus formation. Low frequencies of shoot organogenesis were observed for the remaining cultivars except for cvs. Yes Time and Yes Star, which exhibits no shoot formation at all. In this study, we have developed an efficient in vitro protocol for cvs. Borami and Yes Nuri from suitable explant.

국화 흰녹병균 생태 및 생명공학적 진단에 대한 연구동향

박상렬,안일평,황덕주,장안철,임기병,배신철 한국화훼산업육성협회 2013 화훼연구 Vol.21 No.3

Chrysanthemum is an economically important horticultural crop in chrysanthemum-growing areas including Korea. White rust is the most dangerous disease caused by an obligate pathogen Puccinia horiana. Control of white rust is dependent on chemical treatment and other cultural practices. However, chemical control of disease results in appearance of resistant race of white rust pathogen. Hence, development of chrysanthemum cultivar resistant to white rust is the most desirable. Nevertheless, not much research has been done about white rust pathogen (e.g infection process, pathogen diversity, etc). In order to investigate the way of chrysanthemum to overcome white rust we reviewed literatures reported about white rust pathogen, especially in terms of disease/life cycle and ecology of P. horiana and disease assessment based on polymerase chain reaction in this study. This review will be helpful for disease control and molecular breeding of chrysanthemum resistant to white rust. 국화는 국내외적으로 주요 화훼작물이지만 국화 흰녹병은 안정적 생산에 큰 걸림돌이 되고 있다. 현재까지 국화 흰녹병 방제는 농약살포를 통한 화학적 방제와 다습한 재배환경을 개선하는 재배적 방제에 의존하고 있지만, 살균제 저항성을 갖는 새로운 병원균 출현으로 농약 살포를 통한 병 방제에는 한계가 있어 병 저항성 품종 개발이 절실하다. 흰녹병은 순활물기생균인 Puccinia horiana에 의해 발생하는 곰팡이 병으로 이로 인한 경제적 손실이 크지만, 다른 주요 작물병과 비교하여 상대적으로 연구가 미흡하다. 특히 병원균의 전파 경로와 병원성의 다양성(pathogenic diversity), 병원균 침입기작 및 기주식물과의 상호작용에 대한 전반적인 지식 부족으로 효과적 농약 살포 기준 설정과 병저항성 품종개발에 어려움이 있다. 따라서 본 논문에서는 이러한 과제를 해결하는데 기초자료를 제공하고자 각 연구분야별로 현재까지 발표된 연구결과를 정리하고 앞으로 요구되는 연구과제에 대하여 모색하여 보았다. 특히 효과적 약제처리 기준 설정과 병저항성 품종 개발의 출발점이 되는 흰녹병균의 생활사와 생태, 병원균 DNA 정보를 이용한 조기진단, 병원균의 병원형 등에 관해 현재까지의 연구결과들을 정리하였다. 앞으로 흰녹병균의 식물체 침입 기작에 관한 종합적 이해의 폭을 넓히고, 병원균 침입 시 식물체내에서 발병과 병저항성 유도 요인에 대한 분자 수준에서 연구가 진행된다면 흰녹병균 저항성 품종 육성 시기를 앞당길 수 있으리라 사료된다.
