The experiment was conducted to obtain basic information on breeding of flue-cured tobacco varieties. Nine cultivars and partial diallel set of 36 F1 hybrides were grown at Taegu Experiment Station, Korea Ginseng & Tobacco Research Institute in 1983. Estimated heritability in the narrow-sense ranged from 66.21% to 94.12% for yield, leaves per plant, days to flower, leaf weight, leaf width, leaf shape, nicotine content and reducing sugar content, while that for stalk height, leaf length, midrib weight and midrib width ranged from 28.12% to 56.25%. The genotypic correlations were positive among yield, leaf weight, leaf length, leaf width, midrib weight and midrib width in the middle leaves, days to flower, nicotine content and reducing correlated with leaf length than leaf width. At the path coefficient analysis of the effect of leaf and midrib characters upon yield according to stalk position, leaf weight, leaf width and midrib width in the middle leaves, and leaf weight, and leaf width in the top leaves showed high direct effects.

This study was conducted to analyze the morphological characteristics such as flower color, flower type, flower diameter and flower stalk, and the main annual production yield, and genetic similarity of twenty four Gerbera species growing in Korea. Most of flower colors were pink. The numerical order of flower color was pink, orange, red, double-colored, and milk-white. Majority of flower types were sin81e or semidouble flowers. A few species were double flowers. flower diameters were from 7 ㎝ to 12 ㎝, showed significant differences compared to other characteristics. Flower stalks were ranged from 55 ㎝ to 65 ㎝. Only one species was the shortest as 55 ㎝. The others were similar size as about 65 ㎝. Main annual production yields were between 190 and 400 blossoms. Fifty seven reproducible polymorphic bands from eighty primers were used for analyses of genetic similarity. The genetic similarity of 24 collected Gerberas was largely classified into five groups. The average similarity coefficient was 0.72 ranged from 0.50 to 0.90. The highest similarity coefficient was shown between 'Sardana' with red/white flower color and double flower type, and 'Tamara' with orange flower color and double flower type as 0.90.

작약(芍藥)의 화뇌제거시기가 생육(生育), 건근수량(乾根收量) 및 Paeoniflorin함량(含量)에 미치는 영향을 구명코자 시험연구한 결과는 다음과 같다. 1. 작약 재배시(栽培時) 화뇌제거에 따른 경장은 무제거에 비하여 $7{\sim}9cm$정도 제거된 만큼 짧아졌으며, 경수와 경직경은 차이가 없었다. 2. 화뇌제거에 따른 뿌리수와 생근중은 제거시기가 빠를수록 증가하였으며 , 건근수량은 화뢰크기가 10mm정도 될 때 제거한 것이 1,647/10a으로 무제거에 비하여 27% 증수되어 가장 많았다. 3. 화뇌제거시기별 paeoniflorin 함량은 뿌리굵기 5mm와 10mm에서는 무제거와 일정한 경향이 없었고, 15mm이상부터는 화뢰를 일찍 제거한 것이 화뢰 무제거보다 증가되었다. 4. 잎, 줄기의 paeoniflorin 함량은 잎이 줄기보다 높았으며, 생육초기에 높고 후기로 갈수록 낮아졌는데, 화뢰를 제거한 것이 무제거에 비하여 높았다.

The aim of this study was to investigate the characteristics and antioxidant activities of vinegar made with Etteum bell flower root (0.5%, 1%, 1.5% and 2%) during two-step fermentation. Acetic acid was fermented at $30^{\circ}C$ for 16 days and samples of vinegar were extracted at 2, 4, 6, 8, 10, 12 and 16 days. The pH of Etteum bell flower root vinegar did not significantly differ among the samples, but the acidity increased during fermentation. Alcohol content decreased at 16 days of fermentation and less than 1% alcohol was shown in all samples after fermentation. The pure acetic acid yield was 88.85~98.97%, whereby the total phenolic compound content and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities increased as the ratio of the Etteum bell flower root increased. The sensory scores of vinegar fermented with 1.5% Etteum bell flower root are greater than those of vinegar prepared by other treatments. Therefore, vinegar with 1.5% Etteum bell flower root added is considered to be the most suitable for manufacturing.

본 실험은 '설향' 딸기에서 정식날짜와 정식전 단근처리 및 정식후 굴취처리가 생육, 출뢰율 및 수확량에 미치는 영향을 조사하였다. 60~70일 묘령의 모종을 9월 7일, 9월 14일, 9월 21일 정식하였고 단근처리는 전체 뿌리의 25%, 50%를 각각 잘라내어 무처리와 비교하였다. 굴취처리는 9월 7일 정식한 묘를 10일후 굴취한 다음 재정식한 것과 20일후 굴취하여 재정식한 것을 비교하였다. 정식일이 늦을수록 지상부 생육이 억제되고 수량이 감소하였다. 정화방과 액화방 출뢰는 다소 앞당겨지는 경향이었다. 단근처리와 굴취처리는 지상부 생육이 억제되고 수확량이 감소하는 경향이었고 25% 보다 50% 처리구에서 더욱 확연하게 보였다. 단근처리시 정화방과 액화방 출뢰일은 무처리에 비해 늦추는 경향을 보인 반면 정식 20일후 굴취처리에서 액화방 분화를 약 7일 정도 앞당길 수 있었으나 수확량은 무처리에 비해 낮은 결과를 보였다. 따라서 액화방의 분화를 앞당기기 위해서는 강한 근권부 스트레스가 필요할 것으로 판단되나 수량과 생육을 낮추는 요인으로 작용하므로 재배시 신중한 판단이 요구된다.

This study was carried out to utilize the byproducts (flower, immature and mature berry, leaf and stem) of ginseng. Yield of byproducts were $32.7{\pm}9.8g$ in flower, $68.2{\pm}2.2g$ in immature berry, $48.5{\pm}4.3g$ in mature berry, $316.2{\pm}20.5g$ in leaf, and $296.6{\pm}15.4g$ in stem per $3.3m^2$ ($180{\times}90cm$, ginseng root $675.5{\pm}35.7g$/drybasis. The total saponin contents of ginseng byproducts and root are $52.36{\pm}1.24$, $68.71{\pm}1.98$, $168.89{\pm}0.57$, $68.26{\pm}1.32$, $7.85{\pm}0.61$ and $35.08{\pm}0.96$ mg/g, respectively. The main ginsenoside of all byproducts was Re and the highest content was $132.23{\pm}1.56$ mg/g in mature berry. But flower and berry was not detected Rf and Rh1, respectively. Total polyphenolic compound content on mature berry was the highest, $2.242{\pm}0.140%$, after, immature berry > leaf > flower > root > stem order. The DPPH radical scavenging activity on mature berry was the highest, $0.115{\pm}0.004$ mg/mL($IC_{50}$), and the others were the same order of polyphenolic compound and ginsenoside content on byproducts.

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 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.

국내 재배환경에 적합한 다수성인 거베라의 우수 신품종 육성을 위하여 경남농업기술원 화훼연구소에서 2000년부터 교배조합 육성을 위하여 국내의 재배농가와 종묘업체로부터 품종을 수집한 후, 2002년 3월에 황색 대륜계의 '99-가-2'를 모본, 핑크색 대륜계의 '99-나-7-6'을 부본으로 인공교배를 실시하여 교배조합으로부터 8475개의 종자를 획득하였다. 교배 후 결실이 된 조합은 채종 즉시 파종 하였으며, 파종 1개월 후 발아된 807개의 유묘는 본엽이 4~5매 전개되었을 때 화훼연구소 유리온실 내의 선발 포장에 정식하였다. 그 후 교잡 1세대의 특성검정 결과, 화색이 선명하고 수량이 많은 우수 4개체 (02036-122, 345, 578, 705)를 1차로 선발하였다. 그 후 특성이 우수한 02036-578(경남 G-30)개체를 생장점배양에 의해 개체증식 후 화훼연구소 유리온실내의 특성검정 포장에 정식하여 2004년 9월부터 2007년 8월까지 3회에 걸쳐 생육 및 수량특성 검정을 실시하였다. 특성검정을 실시한 결과 화색, 화형, 수확량 등 품질과 수량이 우수하다고 판단되어 2007년 농작물 직무육성 신품종선정위원회의 심의를 거쳐 "Golden Time"으로 명명 품종등록 하였다. "Golden Time"은 황색 반겹꽃 절화용으로 수량이 많고 화형이 안정된 대륜화로서 화색과 화심색이 잘 조화된 기호도가 높은 품종이다. 본당 수량은 연간 3회 검정 결과 평균 49.5개이며, 평균 절화수명은 12.3일이다.
