Lycopene is the red-coloured carotenoid predominantly found in tomato fruit and one of the major carotenoids in the diets of North American and Europeans. Interest in lycopene is growing rapidly following the recent publication of its effects as a natural antioxidant and prevention of cardiovascular disease and cancers. Lycopene, a polyene hydrocarbon carotenoid haying 13 double bond, of which 11 are conjugated double bonds in a linear array exhibits a strong antioxidant property almost twice as strong as that of ${\beta}$-carotene. Lycopene has been shown in recent epidemiological and experimental studies to protect against oxidative damage of DNA which plays an important part in development of various cancer. Lycopene also contribute towards reducing the risk of cardiovascular diseases by preventing oxidation of low-density lipoprotein(LDL) cholesterol. This review summarize our knowledge and the current understanding of lycopene in human health as well as the results of experiments we conducted. We conducted experiments for investigating the effects of antioxidant in broiler and the possibilities of production of high quality eggs containing lycopene by the dietary lycopene supplementation with synthetic lycopene or tomato paste. The results shows that thiobarbituric acid reaction substances(TBARS) values in process of LDL oxidation in blood serum of broiler were significantly decreased by dietary lycopene and tomato paste. The dietary lycopene supplementation resulted in improved egg yolk color and in decreased the malondialdehyde (MDA) of egg yolk after 4 wk of storage at room temperature significantly(P<0.05). The dietary tomato paste was more effective in the MDA reduction compared to the lycopene(P<0.05). The contents of lycopene in egg yolk of the lycopene supplementation groups were significantly higher than those of the control group.

The Average daily PET (Potential evapotranspiration), evaluated based on the last 30 years meteorological data and the lysimeter experiment carried out by RDA during 11 years, of 9 regions in Korea for the tomato cultivated in greenhouse, was $3.41mm\;day^{-1}$. Two kinds of water saving irrigation standard (WSIS), deficit irrigation standard (DIS) and partial root-zone drying irrigation standard (PRDIS) that include the irrigation interval and the amount of irrigation water according to the region, soil texture and growing stage, were established. According to the DIS and PRDIS, the cultivator can save water up to 29.2% and 53.7%, respectively, for tomato cultivation in greenhouse compared to the full irrigation standard (FIS) which established in 1999. WSIS can be used easily by the cultivator without complicate procedures such as soil sampling and measurement of soil water status by expensive sensors. But the cultivator should care about irrigation method such as PRDI (partial root-zone drying irrigation) without yield decrease.

Eight potato-producing provinces of Iran were surveyed during the growing seasons of 2004-2006 to detect the presence of Tomato yellow fruit ring virus (TYFRV), a tentative species in the genus Tospovirus. A total of 1,957 potato leaf samples were collected from plants with tospovirus-like symptoms of chlorotic or necrotic spots, chlorosis and necrosis. The samples were tested by enzyme-linked immunosorbent assay using TYFRV-specific antibodies. Among those tested, 498 samples (25.4%) were found to be infected with the virus. The virus was detected in 72.4% of the potato fields in all provinces surveyed. Thirteen potato isolates of TYFRV were selected for further biological and molecular studies. Based on their reactions on Nicotiana tabacum plants, the isolates were separated into two groups, namely L (local infection) and N (systemic infection). The nucleotide sequences of the nucleoprotein (N) genes of the isolates were determined and compared with the homologous sequences in Genbank. No recombination evidence was found in the isolates using different recombination-detecting programs. In the phylogenetic tree, the potato isolates fell into two major groups: IRN-1 and IRN-2 corresponding to the two biologically separated groups. This study shows for the first time the biological and phylogenetic relationships of geographically distant TYFRV isolates from potatoes in the mid-Eurasian country of Iran.

Crown rot was found find tomatoes growing on a rockwool culture system in a glasshouse at Dongkwangyang in 1992. The disease occurred on the stem of 'Trust' tomato plants with 3~4 cluster of flowers. Infected plants showed stem girdling and necrosis at or slightly above the rockwool line. Internal tissues of crown and stem including cortex, vascular bundle, and pith became decayed resulting in a chocolate-brown discoloration extending no more than 10~15 cm above the crown. Diseased tomato plants with the similar symptoms were found at Ansung and Taejon where tomatoes were grown on either rockwool or soil in plastic greenhouses. The size of macroconidia of Fusarium isolated from a diseased plant was 26.0~41.6$\times$2.9~4.7${\mu}{\textrm}{m}$, and microconidia were formed on short monophialide and the size was 3.6~12.5$\times$2.9~3.6 ${\mu}{\textrm}{m}$. Morphological characteristics and inoculation tests indicated that the causal organism of the disease was Fusarium oxysporum.

This study was carried out to breed and develop high quality and functional nutrient tomato with multi disease resistance as well as a stable growing adaptation for fresh market usage under protected plastic houses cultivation. The materials were used 5 inbred lines and their 6 hybrids of large tomato group, which have been bred and developed from 1999 to 2007 in Division of Plant Resource Department of Chungnam National University. Fruit weight showed hybrid vigor effect that $F_1$ hybrids weighed more than their parent lines, fruit shape formed three type of oblate, deep oblate and globe shape, in firmness and pericarp thickness have got a high significant correlation, inbred DN611 line was measured the most firm fruit with 6.04 mm pericarp thickness. In fruit color at maturity, pink color crossed to red color appeared all red fruit color in the $F_1$ hybrids, it means red skin color is a dominant gene compared to pink skin color is a recessive gene in tomato, while between fruit skin color and shoulder part color showed no any co-relationship. The sugar content and titratable acid of $F_1$ hybrids inherited an intermediate data of their parent lines, the flavor of KP543 inbred line and the hybrid (JB535 x KP543) revealed the better taste with high brix and proper titratable acid content$^{*}$. In beta carotene content DN611 line showed 2~3 times higher than other materials so that its 3 hybrids contained an increased level of beta carotene, lycopene content was not so much difference among inbred lines and $F_1$ hybrids, of them MD508 contained higher of 8.72 mg and hybrid (JB535 x JA517) had 8.05 mg lycopene content per 100 g fruit, overall pink skin color and red skin color measured a higher lycopene content than yellow and orange skin color at ripe stage. In disease resistance test by PCR marker for Fusarium race2 (I2), Nematode (Mi1), ToMV ($Tm2^2$), Cladosporium (Cf9), (JB535 x JA517) hybrid have got multi-resistance with homozygote band in Nematode, ToMV, Cladosporium and heterozygote band in Fusarium race2. Through this breeding program we could select high quality and functional nutrient with multi resistant $F_1$ hybrids and inbred lines in tomato which are two best hybrids (JB535 x MD508), (JB535 x JA517), additionally developed high beta carotene inbred line DN611 and increased the level of lycopene inbred line MD508. These results will be very useful to make a high quality tomato variety continuously.

본 연구는 배지 구성물질로서 발포 유리질 소재(CGF)와 탄화 밤나무 목재입자(CCW)를 이용하여 배지를 재발하고 원예재배용 배지의 국산화를 위해 수행되었다. 토마토 종자는 발포 유리질 소재, 탄화 목재입자, 입상암면(GR), 그리고 피트모스를 혼합한 4종의 배지를 만들어 플러그 트레이에 충진하여 종자를 200구 플러그 트레이에 4반복으로 파종한 후 fog 번식상에서 3일간 발아시켰다. 발아 후 양지붕형 유리온실에 난괴법으로 배치하여 저면관수로 양액을 공급하여 육묘하였다. 상업적으로 이용되는 공정육묘 배지(토실이)를 대조구로 이용하였다. 플러그묘의 생육은 파종 후 31일째 측정하였다. 모든 처리에서 유사한 생육결과를 나타냈지만 특히 CCW(67%)+peatmoss(33%) 혼합배지에서 초장, 뿌리등급, 생체중, 그리고 배지의 기상과 가비중이 다른 처리에서보다 유의성 있게 좋았다. 모든 배지의 pH는 6.3∼7.4의 범위로 측정되었다. CGF와 입상암면의 혼합비율이 증가할수록 배지의 pH는 증가하였다. 재배 후 배지의 EC는 대조구에서 가장 높았으나 독성증상은 관찰되지 않았다. 엽수와 엽록소 함량은 처리간 유의성이 없었다.
