Phomopsis seed decay (PSD) is part of a major fungal disease complex found in most soybean production areas of the world. To establish the genetic linkage map and efficient soybean breeding program, DNA markers were surveyed for polymorphism between PSD resistant (cv. PI 417479) and susceptible (cv. Hwaeomput-kong) varieties. F2, BC1F2, BC2F2 and the corresponding F2:3 population families were used to evaluate the correlation between molecular markers and resistance to PSD. In SSR analysis, Sct_033 was the most significantly associated with PSD resistance among selected eight primers. AF1, AF2, and AF3 were also selected in AFLP analysis. And a few promising lines could be selected from two times of back cross. Especially a breeding line SS01415-8-1 was developed, which has high seed quality such a large seed size, bright hilum color, round shape, and etc. It might be considered a good breeding material for new recommend variety having resistance gene to PSD with good seed quality.

Blast resistance of 18 rice cultivars which recommended as a high quality rice cultivars evaluated by blast nursery test, seedling test, and field screening and sequential planting methods. Sangmibyeo, Hwayeongbyeo, and Dongjin 1 were showed high resistance reaction to leaf blast at the blast nursery continuously, while Chucheongbyeo showed highest disease severity. All of the early maturing cultivars, Odaebyeo, Junghwabyeo, and Sangmibyeo, showed the lowest compatibility against 25 blast isolates. Saechucheongbyeo, a multiline variety of Chucheongbyeo genetic background showed 45.8%, half compatibility of 82.6% in Chucheongbyeo against 25 isolates screened. Diseased leaf areas (DLA, %) of cultivars were very low level at all test sites in the field test. Three cultivars, Sangmibyeo, Ilmibyeo, and Junghwabyeo didn’t show any leaf blast lesions across the test sites. The most variable incidences of panicle blast were observed on Odaebyeo which was 42.4%, 0.4%. and 0.0% at Jaecheon, Naju, and Chuncheon, respectively. In the sequential planting method, four rice cultivars, Nampyeongbyeo, Sindongjinbyeo, Hwayeongbyeo, and Junambyeo showed less than 40% disease leaf area (DLA) from 1st planting to 7th planting, so those cultivars were considered as a durable resistant rice cultivar against rice blast diseases.

This study was conducted to investigate nitrite scavenging and Angiotensin Converting Enzyme (ACE) effects by antioxidant ingredient and the contents of phenolic compounds is isolated and purified from various sweetpotato cultivars. Various sweetpotato cultivars contained 4 phenol compounds including gallic acid, chlorogenic acid, gentisic acid and caffeic acid. The range of total phenol compound contents within cvs. Saengmi, Seonmi, Hongmi and Zami was at 23.0~48.8mg/100g and cv. Zami containing anthocyanins pigment whose total phenol compound content was at 48.8mg/100g was by far higher than the other cultivars. The assay of antioxidant activity using solvent fractionated extraction methods was investigated in various sweetpotato cultivars. Antioxidant activity of ethyl acetate (41.2~86.2%) was much higher than chloroform and butanol. Antioxidant activity from cvs. Sangmi, Seonmi, Hongmi, Shinyulmi, Zami and Sinchunmi was much higher than α-tocopherol well-known as natural antioxidant. Rancidity inhibitory effect about soybean oil of extracts fractionated by ethyl acetate from cvs. Saengmi, Seonmi, Hongmi and Zami was high considerably. Ethyl acetate layer among various solvent fractionated extraction had a good effect on nitrite scavenging rate but not had a effect on AEC inhibitory. Solvent of column chloromatography to isolate antioxidant contents from ethyl acetate layer was even better on 30% (MeOH) : 70% (Water) condition. There are 5 ingredients at HPLC chromatogram and antioxidant activity effect of individual ingredients was slightly better on Rt 11.9 and Rt 16.9 fraction.

Transient expression profiles for several chimeric β-glucuronidase (GUS) gene constructs were determined in microspore-derived embryos of wheat following microprojectile bombardment. The constructs analyzed consisted of the uidA (GUS) reporter gene driven by six different promoters [Cauliflower Mosaic Virus 35S (CaMV35S), Nopaline synthase (NOS), Mannopine synthase (MAS), Chlorella Mosaic Virus Adenin methyltransferase (AMT), maize Ubiquitin 1 (UBI1), and enhanced 35S (E35S)]. The total numbers of GUS blue spot were determined manually under a dissecting microscope after histochemical staining for GUS. Results suggest that the E35S promoter is the most active and UBI1 promoter is the second active in embryos or embryogenic calli derived from wheat microspore. In addition, by flurometric assay on GUS, the E35S promoter was the best. Therefore, both UBI1 and E35S promoter are suitable for constitutive expression of the gene of interest in microspore-derived embryos of wheat. This information describing promoter functionality in wheat will be important when designing gene constructs for traits modification and when choosing appropriate cultivars for improvement through gene transfer experiments.

The genetic diversity was evaluated using RAPD and ISSR among natural populations and Korean wheat cultivars (Triticum aestivum). Understanding the genetic diversity of putative parental and wild stocks would be useful in wheat breeding programs. Ninety three populations were evaluated with fifty RAPD and three ISSR primers. A total of 185 RAPD and ISSR polymorphism were produced. These markers were considered to estimate the genetic distance among accessions. The genetic similarity ranged from 0.41 to 0.86. The dendrogram were constructed by using the UPGMA clustering algorithm based on genetic similarity. The genetic diversity within and among accession was assessed through Principal Component Analysis (PCA) for statistics analysis. In cluster analysis, four groups were clustered and 17 accessions were not clustered. The PCA was corresponded well to the result. This study provides basic information about the genetic relationships for breeding purposes.

Perilla is an oil and vegetable crop growing in Korea, Japan, and China. We have conducted a field expedition for collecting Perilla germplasm in Korea in 1998 and 2002. P. frutescens var. frutescens was found to be grown and cultivated in large scale throughout the country, whereas var. crispa was not seen. Weedy types of both var. frutescens and var. crispa were often found in roadsides, waste lands and areas around the farmer’s fields. Total number of collection was 176 with 123 accessions of cultivated type of var. frutescens, 33 accessions of weedy type of var. frutescens, and 20 accessions of weedy type of var. crispa. The accessions of cultivated var. frutescens had four different seed coat colors; white, gray, brown and dark brown. Brown and dark brown types were more frequently found than the white type and distributed from north to south of Korea, whereas the white type was mainly found in southern part of Korea. The seeds of cultivated var. frutescens were either soft or hard and large in size (> 2mm), whereas seeds of both weedy types were small and hard with dark brown color. The accessions collected will be useful for preserving genetic diversity of this crop for further breeding programs of Perilla crops.

Identification of QTLs for some agronomic traits under two different N-fertilizer conditions in rice
This study was conducted to identify QTLs for some agronomic traits under two different N-fertilizer conditions. A recombinant inbred population (DT-RILs) between Dasanbyeo (a tongil type rice, derived from an indica × japonica cross and similar to indica in its genetic make-up) and TR22183 (a Chinese japonica variety), consisting of 166 F8 lines, was developed and used for mapping. A frame map of 1,409 cM containing 113 SSR and 103 STS markers with an average interval of 6.5 cM between adjacent marker loci was constructed using the DT-RILs. The DT-RILs were cultivated in ordinary N-fertilizer (N-P2O5-K2O=100-80-80 kg/ha) condition and low N-fertilizer (N-P2O5-K2O=50-80-80 kg/ha) condition in order to compare the different N-fertilizer effects. Grain yield was positively correlated with spikelet number in both conditions. Path analysis revealed that spikelet number is the most positive contributor to grain yield. Twenty-nine single QTLs (S-QTLs) and sixty-five pairs of epistatic loci (E-QTLs) were identified for days to heading, culm length, panicle length, panicle number, spikelet number, spikelet fertility, 1000-grains weight and grain yield in both N-fertilizer conditions. The phenotypic variance explained by these S-QTLs and E-QTLs ranged from 8.8% to 61.1% and from 10.0% to 55.6%, respectively. The total phenotypic variance explained by all the QTLs for each trait ranged from 15.4% to 92.3%.

“Hwanggeumchal”, a new covered waxy cultivar derived from the cross between “Chalssalbori” and “Milyang 65” with waxy endosperm and early maturing cultivars, respectively was developed at Honam Agricultural Research Institute (HARI), NICS, RDA, 2006. The origin of “Hwanggeumchal” is “Suwon 403” (SB942090-B-B-B-42-1). The initial cross was made in 1994 and the selected line showed a high yield and good quality characteristics under yield trial test in 2003. “Suwon 403” consistently performed well for three years (2004-2006) from the four locations of regional yield trial (RYT) in Korea and released as “Hwanggeumchal”. The characteristics of “Hwanggeumchal” were the following: rate I growth habit, green leaf and stem, compact spike and with long rough awns. The heading date was April 30 in upland and April 28 in paddy field, which was 1 and 4 days later than that with check cultivar, “Seodunchalbori”. The culm length was 81 cm which was 3 cm shorter than those with check cultivar. It showed spike length of 4.5 cm and 633 spikes per m2, 64 grains per spike, 27.6 g of 1,000-grain weight and 632 g of test weight. It showed stronger winter hardiness and higher resistance to barley yellow mosaic virus (BaYMV) than those with check cultivar. It had yellow aleurone and showed higher water absorption, expansion rate and total phenol content than those of check cultivar, but lower protein, β-glucan content and pearling rate. The average yield of the pearled grain in the RYT was 4.04 ton ha-1 in upland and 4.12 ton ha-1 in paddy field, which was 10% higher and 4% lower than that of the check cultivar, respectively. This cultivar would be suitable for the area above the daily minimum mean temperature of -8℃ in January in Korean peninsula.
