  • There are some international standards and organization controling the quality characteristics of varieties and seeds such as UPOV, OECD, ISTA, AOSA. The National List system to check variety performance such as quality characteristics of plant varieties and seeds was established by each countries. The UPOV (International Union for the Protection of New varieties of Plant) regulates the requirement of plant variety protection that is distinctness (D), uniformity (U), stability (S) (here in after called DUS), Novelty and Denomination, and some quality characteristics are used to examine the requirement of plant variety protection by each crops. OECD (Organization for Economic Cooperation Development) seed scheme regulates the seed certification for seed trade between countries. ISTA (International Seed Testing Association) and AOSA(Association for Official Seed Analyst) regulates the seed analysis standard and methods. Most of the countries in Europe has the National List system, which check the value for cultivation and use(VCU), that is to say, variety performance such as yield, quality and stress to environment. All the seeds should be enlisted in the National List before sell the seed in their country. All the quality characteristics checked variety performance are for instance, amylose and amylopectin content in rice, molting quality, $\beta$-glucan, protein in barley, protein and sugar content in soybean, sugar and amylopectin content in corn etc. Conditions for the protection of new variety of plant are DUS. Quality characteristics may be the important characteristics and used to check DUS in crop by crop. It is very important to develop a new characteristics and establish standard method fur examine the VCU and DUS test for each crop.

  • Characteristics of seed and plant growth of the nine local collections of the medicinal plant, Agastache rugosa were evaluated. Seed size of the collection from Garyungsan was larger than the others. Seeds of Damyang collection were the smallest in size. Seeds of the collections were mostly oval shaped. There were no differences between brown and black seed coat color groups in seed width, ratio of seed length to seed width and 1,000 seed weight. Stem lengths of Garyungsan and Bongpyung collections were 99.9 and 95.6 cm, respectively, and were longer than Damyang and Jindo collections. Garyungsan collection had long leaf shape. Leaf size was the smallest for Damyang collection, but was the largest for Bongpyung collection. Inflorescence length of Mokpo collection (15.6 cm) was longer than the average over all collections (12.3 cm). Damyang collection was the shortest (10.1 cm) in inflorescence. Top dry weight of each collection from Soonchun, Bongpyung, Mokpo, Jindo, and Gurye was greater than the average over all collections (20.38 g/plant). Jinju and Damyang collections had less top dry matter than others. There was no difference in the growth traits examined between brown and black seed coat groups. The brown seed group was greater in leaf weight than the black seed group. However, these two groups were not different in stem and inflorescence weight. Collections of A. rugosa from Bongpyung, Soonchun, and Mokpo were promising for commercial cultivation because of their great top dry weight, especially in leaf and inflorescence.

  • We manufactured the sausages replaced part (8%) of the pork fat (20.8%) with pepper seed powder (1%) and pepper seed oil (7%). The treatment of pepper seed did not affect pH and microbial quality, but decreased TBARS and VBN of sausages. Although the addition of pepper seed hardly changed textural properties of sausages except for increasing cohesiveness, it enhanced sensory characteristics such as taste, appearance, and overall acceptability. As expected, significant reductions were observed in the content of calorie, total fat, saturated fat, and sodium by replacing pork fat with pepper seed oil and pepper seed powder in sausages. Therefore, pepper seed is good enough to improve the sensory and nutritional quality of sausages.

  • The purpose of this study was to evaluate agronomic characteristics and identify the useful traits to utilize the wheat genetic resources for breeding programs by understanding the phenotypic variation among germplasm through multivariate analysis. In this study, a total of 394 wheat accessions were characterized for 15 agronomic traits using the National Agrobiodiversity Center (NAC) descriptor list, of which 31 accessions from 6 species and 363 unidentified accession (Triticum spp.) available at the NAC, Rural Development Administration (RDA), Korea. Growth characteristics such as leaf width, culm length, spike length, spikelet length, solid stemmed, days to heading, days to maturity, grain-filing period, and also seed characteristics such as width, height, area, perimeter, circle, solidity, and germination percent were studied. Among the 15 agronomic characteristics, the germination percent showed the smallest variation between resources (CV = 0.4%), and the spikelet length (CV = 66.5%) showed the highest variation. A strong positive correlation was found between seed traits such as seed height and seed area (r = 0.90), seed height and seed perimeter (r = 0.87) and seed length and width (r = 0.80). Principal component analysis (PCA) was conducted and the first five principal components comprised 76.7% of the total variance. Among the first five PCs, PCI accounted for 28.5% and PC2 for 20.0%. Wheat resources (394) were classified into four clusters based on cluster analysis, consisting of 215 resources(I), 117 resources(II), 48 resources(III), and 14 resources(IV). Among the clusters, the resources belonging to Cluster III showed the lowest seed width, height, area, and perimeter characteristics compared to other clusters. The wheat resources belonging to cluster IV had small seed width and low germination percent, but took longer to form heads and mature than resources in other clusters. These results will serve as the basis for further genetic diversity studies, and important agronomic characteristics will be used for improving wheat, including developing high-yielding and resistant varieties to biotic and abiotic stresses via breeding programs.

  • This study investigated the effects of mustard seed extracts on physicochemical and storage characteristics of dry-aged pork loin ham during the aging period. In experiment 1, antioxidant activity was assessed for mustard seed extracted with varying ethanol concentrations and the results showed high antioxidant activity at 25%, 50%, and 75% ethanol concentrations. In experiment 2, pork loin was treated with mustard seed extracts obtained using different ethanol concentrations: not treated (control), 25% (MS25), 50% (MS50), and 75% (MS75). Physicochemical and storage characteristics of pork loin ham were measured in wk 0, 2, 4, and 6. The pH, aw, CIE b*, thiobarbituric acid reactive substances and volatile basic nitrogen values were lower in treated samples compared to the control (p<0.05). In conclusion, applying mustard seed extracts, particularly MS75, in the dry-aged pork loin ham production process could enhance storage stability and improve color attributes without having negative impacts on product quality.

  • Background: This study was conducted to investigate the growth characteristics, root yield and curcuminoid content of turmeric (Curcuma longa L.), cultivated using mother seed rhizomes (MR) and finger seed rhizome (FR) of different sizes. MR are attached to the stem, and FR are connected to the MR, and are used as a general seed rhizome. Methods and Results: Seed rhizomes of different types and sizes were used: large, medium and small for FR, and large, half-sized, and small for MR. These were assigned to the experimental groups and cultivated under greenhouse conditions. The growth characteristics, root yield, and curcuminoid content did not show clear difference between MR and FR, but suggest that the larger seed rhizomes (above 30 g) could have higher root yields. On average, harvested mother rhizomes (HMR) contained more curcuminoid than harvested finger rhizomes (HFR), while the yield of HFR was higher than that of HMR. The higher weight of harvested roots correlated significantly with elevated curcuminoid content. Conclusions: The two seed rhizomes, MR and FR, did not differ in root yield and curcuminoid contents, but larger seed rhizomes may produce better root yields. This suggest that the optimum seed rhizome is larger FR, to produce higher yields and quality in turmeric root production.

  • This study was carried out to obtain the several data for improving the seed supply in Pinus densiflora. Seed characteristics and germination properties according to change of cone production from 2003 to 2006 were analyzed in three plus stands of P. densiflora. P. densiflora showed good production at interval of two years in the periodicity of seed production. Seed potential and percent of filled seed (PFS) among the major seed characteristics showed positive relations to the change of cone production, whereas percent of developed seed (PDS) and seed efficiency showed opposite trend. As a result of regression analysis between seed characteristics and cone production, seed potential ($R^2=0.682$, p<0.01) and PFS ($R^2=0.161$, non-significant) presented positive correlation with cone production while PDS ($R^2=0.418$, p$R^2=0.308$, non-significant) presented negative correlation. In germination properties percent of germination (PG) showed similar tendency to cone production, while mean germination time (MGT) showed opposite tendency. As a result of regression analysis between germination characteristics and cone production, PG showed positive correlation, whereas MGT showed negative correlation. Therefore, we could expect high germination percentage and short period for germination when we harvested cones at good cone production time.

  • To examine the quality characteristics of bread made of different amounts of chia seed powder, a functional food ingredient, this study made bread by adding chia seed powder by 1%, 3%, and 5% of the flour weight. When bread dough properties were determined using mixograph, all doughs were appropriate for bread-making. In the evaluation of fermentation rate, the dough with 3% of chia seed powder CS 3 showed the most favorable fermentation rate during the first 60-min fermentation of the bread. According to CrumbScan, the fineness of bread pores were higher in control group than bread loaves containing chia seed powder. The volume of bread in control group was significantly lower than those of other experimental groups. The volume and specific volume were highest when chia seed powder was added by 3%. According to preference analysis, appearance and taste was best in CS 3, showing the highest overall score in preference. Therefore, the optimum amount of chia seed powder is identified to be 3% in bread-making.
