This experiment was aimed to find out the measures or soil managements in continuous melon cultivation and to produce the high quality of yellow melon in plastic film house culture. The experiment was designed with surveying of farmer's field and conducted for 4 years. The most effective measure of soil managements was to cultivate paddy rice in June after harvesting the melon and next ways were treated with submergence or the plastic film for 40days during the period of high temperature of summer and plowed over 50cm depth with plough machine. To decrease the soil problems in continous cultivation, the addition of red earth soil of 500M/T per 10a with increasing the application rates of rice straw and fertilizer (N, P, K) in 30% and 10% respectively was effective in plastic film house culture. The effect of soil amendment application was continued for two years at least and it increased the commercial quality and sugar content in brix of yellow melon in 10% and 2.6 degree respectively.

The present study was performed to investigate the pre-harvest residue limit (PHRL) of pesticides namely, metalaxyl-M and flusilazole in oriental melon, and to identify the biological half-life and characteristics of their residues. In this study, pesticides were sprayed once as single spray and double spray on oriental melon. The oriental melon samples were collected at 0, 1, 2, 3, 5, 7, 9 and 11 days before harvest and samples were extracted with QuEChERS method. The residues of both the pesticides were quantified using GC/NPD and LC/MS/MS. The limit of detection was found to be 0.02 mg/kg and 0.01 mg/kg and their recoveries were greater than 95% (95.7% ~ 103.2% for metalaxyl-M and 100.2% ~ 106.8% for flusilazole) for both pesticides. The biological half-lives of both metalaxyl-M and flusilazole were 12 days at single and double spray, respectively. The PHRL of metalaxyl-M and flusilazole was found 1.0 mg/kg and 0.3 mg/kg, respectively for 10 days before harvest. The results of the present study shows the residual level of both the pesticides metalaxyl-M and flusilazole in oriental melon were less than their maximum residual limits.

Addition of starch syrup, table sugar, potato powder, skim milk powder an parched soybean powder to melon flesh was suitable as fermented melon base. The manufacturing process of fermented melon was as follows: Pasteurization for 10 min at $95^{\circ}C$, use of 1% starter culture, fermentation for 12 hours at $35^{\circ}C$ and ripening for 3 days at $8^{\circ}C$. The growth and acid production of Pediococcus acidilactici among several starter cultures were most active for the first 12 hours, but such activities were disappeared during ripening. In the case of Lactobacillus plantarum, the activities were not high during fermentation, which, however, increased during ripening. Throughout the whole manufacturing process, the fermented melon with a mixed culture of P. acidilactici and L. plantarum showed more cell number of each bacterium and higher titratable acidity than that with single cultures. Also P. acidilactici surpressed the growth of L. plantarum during ripening.

Cadusafos and fosthiazate were applied at the rate of 1.8 g a.i./6$\m^2$ as pre-plant or pre-plant＋post-plant treatments on winter-grown oriental melon in a greenhouse soil infested with Meloidogyne arenaria. Nematicides reduced root-knot nematode population from 35 to 90% compared with control； fosthiazate was better than cadusafos (P ＝ 0.003) and fosthiazate pre-plant＋post-plant application reduced nematode population densities as much as 90%. Nematicides increased yield in an average of 23% (11-38%) in May, 39% (2-65%) in June, and 31% (12-46%) for the total (P ＝ 0.085). The residue in the fruit of oriental melon by post-plant treatment of fosthiazate exceeded maximum residue limit of 0.2ppm, while the Cadusafos residue was below the limit. It is concluded that fosthiazate cannot be used as a post-plant treatment in winer-grown oriental melon with overall consideration, i. e., danger of residue, value of melon, costs of nematicide, consumer demand on safer agricultural products, and effects of fallow.

This study was carried out to determine the descriptive sensory profile of oriental melon. The sensory profile of oriental melons (cultivated in Seonju, Kyungsangbuk-do) were used quantitative descriptive analyses and twelve trained panel developed the total forty sensory attributes related appearance, aroma, texture etc. Six appearances attributes and two aromas attributes were derived from whole oriental melon with skin. Five aromas, six tastes and six textures were derived from the mesocarp of oriental melon. And also, oriental melons were analyzed for pH, titratable acidity, solid soluble contents and weight. The weight, titratable acidity and soluble solid content of oriental melons showed significant differences according to samples. And also, in the sensory attributes of these samples by trained panel and consumer test, there were significant differences between organic cultivated samples and conventional cultivated samples. Based on principal component analysis of sensory attributes data by trained panel and consumer, oriental melons were primary separated along the first principal component, which accounted for 27.73% (trained panel test) and 19.82% (consumer test) of total variance (trained panel test; 58.36%, consumer test; 46.18%) between the samples farm, cultivation method, total acidity, sweet aroma, bitterness, etc. Generally, whole oriental melon with skin showed significant differences in the sensory attributes according to cultivation method and farms. But, the mesocarp and endocarp part showed not certainly differences in the sensory attributes between organic cultivated samples except conventional cultivated samples.

Melon (Cucumis melo L.), one of the most important fruit crop species, is cultivated worldwide. In this study, a total of 206 melon accessions conserved at the National Agrobiodiversity Center (NAC) in RDA were characterized for nine morphological characteristics according to the NAC descriptor list. In addition, to confirm the genetic composition of each melon accession, genetic profiling was performed using 20 SSR markers. Among the 206 melon accessions, 159 (77.2%) were collected from Asia. The color of fruit flesh and skin were mostly 'white' (56.0%) and 'green' (49%), respectively. Days to female flowering (FD) and maturity (MD) of the accessions ranged from 58 to 72 and 17 to 63, respectively. The fruit length and width of the accessions ranged from 6.0 to 29.3 and 3.6 to 17.2 cm, respectively. The sugar content (SU) ranged from 2.5% to 13.2% with an average of 7.0%. In correlation analysis, SU showed positive and negative correlations with MD and FD, respectively. The accessions were classified into four clusters by cluster analysis. From the results of genetic profiling using 20 SSR markers, three accessions (K189118, K100486, and K190292) were expected to be inbred lines among 206 melon accessions. These results could expand the knowledge of the melon germplasm, providing valuable material for the development of new melon varieties to suit consumer tastes.

We investigated the physicochemical and sensory characteristics of oriental melon (Cucumis melo L.) to provide a consumer-oriented quality index. Oriental melon fruits were harvested at 20, 25, or 30 days after fruit set (DAFS), and each group was sorted by size (small, medium, and large). Fruits harvested at 25 and 30 DAFS had higher CIE $a^*$ and $b^*$ values, higher soluble solids content (SSC), and lower CIE $L^*$, firmness, and titratable acidity (TA) values than fruits harvested at 20 DAFS. Fruits harvested at 25 and 30 DAFS scored more highly for overall acceptance. A significant correlation was found between physicochemical characteristics and overall acceptance. In the delayed-harvest sample, increased sweetness and yellowness, and decreased sensorial texture were associated with an increase in overall acceptance. In principal component analysis, F1 and F2 explained 62.16% and 17.91% of the total variance (80.07%), respectively. Regression analysis of overall acceptance and F1 gave a coefficient of determination ($r^2$) of 0.87. Our results show that consideration of the physicochemical characteristics (CIE value, SSC, pH, SSC/TA ratio, and firmness) and sensory characteristics (yellowness, placenta area condition, oriental melon odor, sweetness, oriental melon flavor, texture, and off odor) of oriental melon in this way can be used as quality indices to predict consumer acceptance.

Agrobacterium tumefaciens-mediated cotyledonary-node explants transformation was used to produce transgenic melon. Cotyledonary-node explants of melon (Cucumis melo L. cv. Super VIP) were co-cultivated with Agrobacterium strains (LBA4404, GV3101, EHA101) containing the binary vector (pPTN289) carrying with CaMV 35S promoter-gus gene as reporter gene and NOS promoter-bar gene conferring resistance to glufosinate (herbicide Basta) as selective agent, and the binary vector (pPTN290) carrying with Ubiquitin promoter-GUS gene and NOS promoter-nptll gene conferring resistance to paromomycin as selective agent, respectively. The maximum transformation efficiency (0.12%) was only obtained from the cotyledonary-node explants co-cultivated with EHA101 strain (pPTN289) on selection medium with 5 mg/L glufosinate and not produced a transgenic melon from the cotyledon or cotyledonary-node co-cultivated with other strains. Finally, five plants transformed showed the resistance in glufosinate antibiotic and the GUS positive response in leaf ($T_0$), flower ($T_0$), seeds ($T_1$) and plantlet ($T_1$). Southern blot analysis revealed that the gus gene integrated into each genome of transgenic melon.
