This research was relative humidity (65, 75, 85 and 95%) growth characteristics of the oak mushroom (Lentinula edodes) 'Nongjingo’. At the relative humidity was 65% in growth chamber. On this condition the moisture content of medium surface was 60.5%. That was lower than other treatments. That condition makes Pileus was 77.1% and stipe was 65%. Among the growth characteristics according to the relative humidity, the pileus diameter at 75% relative humidity were 45.5mm that largest than other treatment and pileus thickness at 75% relative humidity were largest than other treatment. The stipe thickness at 65% relative humidity were 14.8mm that lagest than other treatment. The number of available stipes at 95% relative humidity were 13.3peace/2kg that largest than other treatment. The comparison yield ability of 1 cycle was 104.2g that result in largest than other treatment at 95% relative humidity. This result was associated to the relative humidity of fruiting bodies, the lower relative humidity result in the lower of yield. However, the lower relative humidity result in the higher number of whago, Especially, at the treatment of 65% relative humidity, all the fruit bodies were produced as Whago (dry). Therefore, the higher relative humidity influenced in the higher yield but produced water mushroom. That result was thought that ‘Nongjingo’ would be possible to produce high quality mushroom by adjusting the relative humidity appropriately.

One hundred seventy two accessions of safflower, collected in four countries were investigated for their morphological and biochemical characters in 2014. The accessions were categorized into two groups; South-Central (S-C) Asia and South-West (S-W) Asia, and each group was represented the accessions of two countries. Variation in morphological and biochemical characters was observed between two groups of accessions. The average value of seed weight and range of variability were higher in S-C Asia accessions while S-W accessions exhibited the variation in plant height, leaf length and days to flowering. The average value of oleic and total oil content were higher in S-C Asia accessions, and the values were 19.8%, and 231.4 mg.g-1, respectively, while the range of variability for total oil content was higher in S-W accessions. Plant height exhibited a significant positive correlation with days to flowering (r = 0.625**). Palmitic acid had positively correlated with stearic acid (r = 0.282**) and linoleic acid (r = 0.444**). Oleic and linoleic acid showed a strong negative correlation (r = -0.977**). The first three principal components explained 57% of the total variation. Morphological and biochemical variation exist in different groups of accessions could be useful to breeder for developing new safflower cultivars with high oil quantity and quality.

Ramie (Boehmeria nivea L. Gaudich.) is a hardy perennial herbaceous plant of the Urticaceae family and has been grown as a fiber crop in several countries including Korea for many centuries. Ramie leaves also have been traditionally used as a major ingredient of a type of rice cake called ‘Song-pyun’ in the Southwest area of Korea, especially Yeong-Gwang province. Despite its economic importance, the molecular genetics of ramie have not been studied in detail yet. Genetic resources of ramie were widely collected from domestic local sites by Bioenergy Crop Research Center (RDA) and Yeong-Gwang Agricultural Technology Center. For the systematic and efficient management of the genetic resources, we developed microsatellite molecular markers of ramie. To do this, we generated microsatellite-enriched genomic DNA libraries using magnetic bead hybridization selection method. 216 contigs containing microsatellite repeat motif were generated using nucleotide sequences of 376 clones from the libraries. Primer sets were designed from the flanking sequences of the repeat motif. Finally, we selected 26 microsatellite markers, possibly showing polymorphism among the genetic resources. Results on the genotype analysis of the ramie genetic resources using the microsatellite markers will be presented.

The production of hybrid onion (Allium cepa L.) seed is economically feasible using systems of cytoplasmic-genic male sterility(CMS). The identification of cytoplasm types might be helpful to development of sterile and maintainer lines. Due to this reason, a knowledge of the cytoplasm type is essential for hybrid breeding in onion. Especially, due to the biennial generation time of onion, to distinguish of onion cytoplasm type in individual plant may be helpful to reduce the efforts in a breeding program, when new sterile lines and the corresponding maintainer lines be developed. In our study, we applied the PCR-marker (orfA-501) to identify the cytoplasmic genotypes of collected 100 accessions of bulb onion. Among accessions, S-cytoplasm was found in 57 accessions. Nineteen accessions possessed only N-cytoplasm and twenty four accessions possessed both S- and N-cytoplasm.

This study was conducted to clarify the relation of the species of genus Sorbus in Korea based on multivariate analysis for the morphological characteristics and DNA polymorphism. Twenty-eight quantitative characters were assessed and analyzed by the principal component analysis and UPGMA cluster analysis. From the principal component analysis of 28 quantitative characters, three principal components (PC’s) explained the variation of inter-specific relations among the genus Sorbus. The first PC’s explained 58.95% of the variation with the Eigenvalue of 16.5, and the second and third PC’s showed the Eigenvalue of 8.3 and 3.1 and explained 88.74% and 100.0% of the variation, respectively. Especially, the first PC’s was related in order of the fruit width (FW) and length of terminal leaflet (LTL), petal length (PL), width of terminal leaflet (WTL), and diameter of winter bud (DWB). The second and third PC’s were involved in order of the No. of leaflet (NL), No. of fruit per fruiting lateral (NFL), length of upper rachis (LUR), and diameter of rachis (DR), No. of pistil (NP), respectively. Cluster analysis using them UPGMA method based on the principal components of four species of the genus Sorbus divided into two groups. Group Ⅰ comprises Sorbus commixta and S. sambucifolia var. pseudogracilis, and Group Ⅱ consists of S. amurensis and S. aucuparia. The pattern of DNA polymorphism of the 56 inter-simple sequence repeat (ISSR) markers revealed that different taxa shared different sets of bands, and DNA analysis is useful for taxonomic study on the genus Sorbus.
