Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

패모린경의 무게를 15gr, 3gr, 5gr, 7gr, 9gr의 5등급별로 나뉘어 파종하였을 때에 그에 따른 발아상태, 초장, 개화, 자구 및 수량에 대하여 조사하였다. 1. 인경의 무게가 1.5gr 및 3gr되는 것은 발아시, 발아기간이 5gr, 7gr, 및 9gr되는 것에 비하여 발아시가 늦고 발아기간이 긴 경향을 나타냈고, 초장도 3∼5분지 1밖에 되지 않었다. 2. 개화는 인경이 무겁고 영양상태가 양호한 7gr∼9gr 상태에서 50％∼75％ 였으나, 3gr이하의 것은 1％에 불과했다. 또한 자구는 5gr이상에서 현저한 증가를 보였다. 3. 수량을 증가시키기 위하여서는 5gr이상의 패모를 사용하여야 한다는 사실을 알게 되었다.

조직배양구를 순화시키기 위하여 상토에 정식을 할 때 순화율을 높이고 구 비대에 적합한 재식밀도와 깊이를 구명하고자 시험을 수행되었다. 오리엔탈나리 대표 품종들인 '시베리아'와 '솔본느' 조직배양구의 효과적인 순화를 위한 재식 밀도를 200, 400, 600, 800, 1,000구/$m^2$ 단위로 하였으며, 재식깊이 시험을 위해 상토의 복토를 1, 3, 6, 9, 12cm로 나누어 정식하였다. 오리엔탈나리 '시베리아'의 경우 $m^2$ 당 400구 재식시 생존율 87.3%, 구주 6.4cm, 구중 8.3g, 구주 6cm 이상 비율 61.6%로 가장 적합하였다. '솔본느'의 경우도 400구/$m^2$에서 생존율 88.8%, 구주 5.0cm, 구중 7.1g 으로 가장 효율적인 것으로 생각되었다. 오리엔탈나리 '시베리아'와 '솔본느' 조직배양구의 순화를 위한 적정 재식깊이는 '시베리아'의 경우 지표면에서 3cm 재식구가 생존율 77.8%, 구주 5.9cm, 구중 7.9g, 구주 6cm이상 비율 47.2-51.0%로 가장 양호하였고, '솔본느'의 경우도 3cm 재식구에서 생존율 87.1%, 구주 5.1cm, 구중 6.5g로 가장 양호하였다.

This experiment was conducted to elucidate the effects of mulching materials and removing time of the transparent polyethylene (PE) film on the growth of garlic at Uiseong experimental field, Korea. The experimental mulching materials comprised of transparent polyethylene film (0.025 mm) and net polyethylene (NPE). Plant height and leaf number of garlic were highest at PE treatment when the PE removing date was March 18 and this treatment also promoted the no. of cloves. Length of leaf sheath and bolting rate were highest and bulb weight loss rate was lowest at PE + NPE treatment when the PE removing date was March 18. But clove number was the lowest in this treatment compared to conventional PE film treatment. Conventional mulching method accelerated secondary growth rate but bulb weight loss was vice versa. There were statistically no differences in bulb diameter among treatments but conventional treatment positively focused on bulb diameter. Whenever PE film remove can suppress weeds compared to no mulching treatment but the dry weight of weeds were increasing trends as the removal dates of PE film were delayed. Transparent PE or PE + NPE treatments can be recommended to grow best quality garlic when PE film removing date is March 18.

This study was conducted to investigate morphological characteristics of Korean local garlic varieties and to define the genetic variability and the correlations amongthe characters associated with yield. The plant height, the leaf sheath diameter, the nubmer of leaves, and bulb weight were significantly increased in the garlic plants from heavier seed bulbs. The proportation of six clove bulbs was more than 60% in Seosan variety and this was not realted with the number of cloves in seed bulb. While more than 70% bulbs in Jeoksung and Danyang varieties cultivated in paddy field were composed of 6 or 7 cloves, majority of the bulbs of Euisung and Danyang varieties cultivated in upland were composed of bulbs with 7 cloves or more. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed in bulb weight. GCV and PCV also showed high value in leaf sheath diameter. Thus, there is a greater scope for selection of these characters. The small difference between PCV and GCV values in plant height indicates that the environmental influence would be limited in this character. High heritability was observed of plant height (56.76%) and bulb weight (45.95%). And the weight per bulb (34.24%) exhibited highest genitic advance followed by leaf sheath diameter (18.8%) and plant height (9.61%), and those would be the ideal characters for selelction.

The bulb storability of eight red and ten yellow onion (Allium cepa L.) cultivars grown primarily in Korea was evaluated. During storage, sprouting occurred earlier in red cultivars than in yellow cultivars. In addition, the ratio of sprouted to unsprouted bulbs increased more rapidly in red cultivars than in yellow cultivars. However, not all yellow cultivars had strong storabilities. Bulb storability of three yellow cultivars was as poor as that of red cultivars, suggesting only a slight possibility of a pleiotropic effect of color and bulb storability. Meanwhile, $F_3$ lines of a red cultivar selected based on stronger storabilities showed intermediate storabilities between those of the red and yellow cultivars, implying that strong storability could be obtained by successive selection. In contrast, $F_1$ hybrids from crosses between yellow and red breeding lines showed poor storability compared with the yellow cultivars, indicating that poor storability may be dominant over strong storability. The relationships between color and other traits that potentially affect storability, such as fresh and dry weight, water content, and firmness of bulbs, were evaluated. No significant differences in these traits were observed between the two colors, although the water content of yellow cultivars and the dry weight of red cultivars were slightly higher than their counterparts. Correlation analyses between bulb storability and other traits, including weight, water content, and firmness, also showed no significant correlations. In this study, no correlations were identified between bulb color, storability, and other traits. However, based on these results, red cultivars with stronger storabilities could be developed through successive selection of bulbs with stronger storabilities.

마늘의 육종의 기초자료를 얻고져 주요산지 4지역에서 국내 지방종의 구 특성을 조사한 결과는 다음과 같다. 지방종의 인편수는 4에서 15쪽까지 널리 분포하였으나 6-8 쪽마늘이 70%이상을 점하였다. 국내수집종의 인편무게는 1에서 7.6g까지 넓게 분포하였으나 대부분은 3g이상이 60%이상을 차지하였다. 국내수집종의 인편 평균무게는 수집지역에 따라 차이가 있었으나 대부분이 6-8쪽 마늘에서 가장 무거웠다. 국내수집종의 구중은 인편수가 증가할수록 무거웠다.

Many onion growers and researchers assert that differences in soil type, agricultural practices, weather, and duration of prolonged onion cultivation in a particular field could affect onion bulb quality. This study evaluates the bulb quality of onions grown in different regions and determines the correlations between bulb characteristics and postharvest loss during cold and ambient storage. Soil and onion bulbs were collected from fields in six onion growing regions in Korea, during the growing season of 2011-2012. The fresh weight, dry matter content, and carbon (C), sulfur and magnesium contents of the onion bulbs were significantly affected by the location in which they were grown. Bulbs grown in Muan had the greatest number of scales, thinnest scale thickness, and the highest total soluble solids (TSS) and total flavonoids (TF). Bulbs originating from Jecheon had the lowest pyruvic acid (PA), total phenolics and TF. Storage loss of bulbs from the different regions was similar in refrigerated storage, but differed in ambient temperature storage. Bulb fresh weight was positively correlated with scale thickness (r = 0.617) and cold storage loss (CSL; r = 0.398). Dry matter content was positively correlated with C (r = 0.958) and TF (r = 0.256) contents, while it was negatively correlated with CSL (r = -0.424). CSL was primarily affected by the fresh weight, as well as the dry matter, C, and PA contents of the bulbs, while ambient storage loss was primarily influenced by the amount of TSS.

Optimmum cultivation period was determined for producing seed bulb of Korean native Allium wakegi Araki in vitro in hydroponic culture. The growth gradually increased during cultivation period. In general, plants grown for 5 months produced significantly the highest bulb number and bulb fresh weight per plant. Raising the cultivation period from 1 to 5 months remarkably increased seed bulb yield.

새로운 노지 월동작물과 수출유망 작물을 개발하기 위하여 1995년도에 shallot을 도입하였다. 적응력 시험을 수행하는 과정에서 구 비대기의 고온에 의한 식물체의 조기 고사현상 및 습해 발생으로 수량이 점차 감소되었다. 또한 영양번식체로 세대를 진전시키는데 기인한 종구의 퇴화현상과 같은 문제점이 발생하였다. 이러한 문제점을 해결하기 위하여 연도별 생산성과 지대별 적응성에 따른 shallot의 재배방법을 개발하기 위해 수행하였다. 연도별 생산성은 1995년에는 평균 구중이 18.7 g, 10a당 수량은 4,113 kg이었다. 재배 2차년(1996년)의 평균 구중은 25.8 g으로 무거워졌으나 수량은 10a당 2,013 kg으로 48.9%로 낮아졌다. 재배 3차년의 평균 구중과 10a당 수량은 1996년의 결과와 유사한 경향을 보였다. 재배 4차년(1998년)의 평균 구중은 21.1 g으로 증가하였으나 수량은 10a당 1,246 kg로 도입 당시의 30.3% 수준으로 크게 낮아졌다. Shallot의 고랭지, 준고랭지, 평야지, 해안 지대의 지대별로 적응력을 시험한 결과 식물체 생육은 월동 전 후 및 생육성기인 4월까지는 해안 지대에서 생육이 왕성하였다. 하지만 수확기인 7월에 가까워질수록 준고랭지가 해안 지대에 비해 수량이 57%가 많았다.
