본 연구는 근래에 건강 기능성효과가 널리 알려지면서 수요가 증가함에 따라 재배면적과 생산량이 증가하고 있는 종실용 들깨의 기계화재배를 촉진하기 위하여 수확 때 종자탈립에 의한 손실률은 최소화하고 수량성을 높일 수 있는 최적 파종시기를 설정하고자 수행하였다. 1. 파종기가 늦어질수록 파종후 개화기까지 생육일수는 짧아져 6월 15일 파종대비 6월 30일, 7월 15일 및 8월 1일 파종에서 각각 14일, 26일 및 31~32일 짧아졌으며, 또한 경장과 경태는 짧아지거나 가늘어졌으며 마디수가 적어지는 경향을 나타냈다. 2. 유효분지수는 6월 15일 파종대비 6월 30일, 7월 15일 및 8월 1일 파종에서 각각 82%, 61% 및 56%로 7월 15일 파종부터 급격히 낮아져 수량성 확보에 불리한 것으로 판단되었다. 그리고 최저화방군의 높이는 파종기가 늦어질수록 대체로 짧아지는데, 소담의 7월 15일과 8월 1일 점파구의 경우 15 cm 이하로 예취기를 이용한 기계수확에 불리하게 작용할 것으로 판단되었다. 3. 파종기와 수량성 간에는 고도의 유의성이 인정되었는데, 총수량은 6월 15일, 6월 30일 및 7월 15일 파종에서 통계적 유의차는 없었지만, 종실탈립률의 경우 7월 15일, 8월 1일 (30.3%) > 6월 15일(15.3%) > 6월 30일(13.5%) 파종의 순이었는데, 탈립된 종실을 제외한 순수량은 6월 30일 6월 15일 >7월 15일 >8월 1일 파종 순으로 높게 나타났으며 이러한 경향은 품종 및 파종방법에 관계없이 나타나는 일반적인 특징이었다. 4. 들깨 종실의 단백질 함유율은 파종기가 늦어질수록 대체로 증가하여 8월 1일 파종에서 가장 높았으며, 조지방 함유율의 경우 소담은 6월 15일과 7월 15일 파종에서, 들샘은 6월 30일과 7월 15일 파종에서 비교적 높았으며, 리놀렌산의 함량율은 8월 1일 파종에서 특이적으로 높은 수준을 나타냈다. 5. 위의 결과, 종실용 들깨의 예취기를 이용한 기계수확을 위한 최적 파종시기는 6월 30일 경으로 이때 파종하면 수확때 종실탈립에 의한 손실률은 최소화하면서 수량증대에 유리하여 기계수확에 가장 적합한 파종시기로 판단되었다.

A field trial was conducted for two consecutive seasons (2013/14 and 2014/15), at the Gezira Research Station, Wad Medani, Sudan, to evaluate the agronomic performance of fourteen early maturing soybean germplasm introduced from USA, South Korea, Vietnam, Taiwan, and Croatia, under irrigated cropping environment. Highly significant differences (P ≤ 0.0001) were detected among the fourteen varieties for the eight agronomic traits in 2013/14 and 2014/15. Over the two seasons, Vietnam coll. 1 had the high grain yield (945 kg/ha), followed by N04-9859 (828 kg/ha) and AGS 327 (798 kg/ ha). Days to maturity ranged from 71 to 86 days over the two seasons. In both seasons, Vietnam coll. 1 and AGS 327 had the high agronomic performance in fodder yield, plant height and height to first pod. The agronomic performance of Vietnam coll. 1 and AGS 327 provides a clear example of the adaptability of tropical soybean germplasm to irrigated environments in Sudan comparing to other temperate germplams. The relative high yield of Vietnam coll. 1 and AGS 327 can be maximized by increasing plant populations/unit area. The unique soybean germplasm from the southern US and South Korea is valuable genetics resource for soybean germplasms at Agricultural Research Corporation (ARC), Sudan to broaden the genetic base of the released soybean varieties through introgression of potentially useful genes for drought-related and nutritional quality traits.

The effects of drying temperature on the drying characteristics of soybeans at the different position in the dryer with 28.1% (±0.8) of initial moisture content were studied. Drying temperatures varied at 35, 45 and 55ºC, with a constant inlet air velocity (3 m/s). The local air velocities at a position 1, 5, and 9 were 0.150 m/s (±0.012), 0.247 m/ s (±0.018) and 0.795 m/s (±0.036), respectively. The drying rate increased as the local air velocity increased from 0.150 m/s to 0.795 m/s. The cracked grain ratio increased as the drying rate increased. To prevent quality degradation of soybeans during hot-air drying, the local air velocity should be considered. Thin-layer drying models were applied to describe the drying process of soybeans. The Midilli-Kucuk model showed the best fit (R2>0.99). Based on the model parameters, the drying time to achieve the target moisture content (15%) was successfully estimated. The drying time was strongly dependent on the position in the dryer and the drying temperature.

The milling characteristics of rice using different milling methods (dry and wet) were investigated. Generally, average particle sizes of dry-milling flours were bigger than those of wet-milling flours due to low moisture content. Three theoretical models for milling, such as the Rittinger, Kick, and Bond model, were applied to characterize the milling process of rice. The wet-milling method showed higher value milling constants including Bond’s work index. Baeksulgi was used to study the effect of the milling method and particle size on rice flour’s physicochemical property (water content, color value, and texture). Moisture content and hardness of Baeksulgi were smaller as the particle size became smaller. L value of Baeksulgi was greater as the particle size became smaller. The energy requirement for the milling of grains to obtain a suitable size of particles was estimated by the grinding models. The results of our study might provide a systematic way to estimate the energy requirement to obtain a suitable particle size by milling

Apolipophorin III (apoLp-III) is a well-known hemolymph protein having a functional role in lipid transport and immune response of insects. We cloned full-length cDNA encoding putative apoLp-III from larvae of the coleopteran beetle, Tenebrio molitor (TmapoLp-III), by identification of clones corresponding to the partial sequence of TmapoLp-III, subsequently followed with full length sequencing by a clone-by-clone primer walking method. The complete cDNA consists of 890 nucleotides, including an ORF encoding 196 amino acid residues. Excluding a putative signal peptide of the first 20 amino acid residues, the 176-residue mature apoLp-III has a calculated molecular mass of 19,146 Da. Genomic sequence analysis with respect to its cDNA showed that TmapoLp-III was organized into four exons interrupted by three introns. Several immune-related transcription factor binding sites were discovered in the putative 5’-flanking region. BLAST and phylogenetic analysis reveals that TmapoLp-III has high sequence identity (88%) with Tribolium castaneum apoLp-III but shares little sequence homologies (<26%) with other apoLp-IIIs. Homology modeling of Tm apoLp-III shows a bundle of five amphipathic helices, including a short helix 3’. The ‘helix-short helix-helix’ motif was predicted to be implicated in lipid binding interactions, through reversible conformational changes and accommodating the hydrophobic residues to the exterior for stability. Highest level of TmapoLp-III mRNA was detected at late pupal stages, albeit it is expressed in the larval and adult stages at lower levels. The tissue specific expression of the transcripts showed significantly higher numbers in larval fat body and adult integument. In addition, TmapoLp-III mRNA was found to be highly up-regulated in late stages of L. monocytogenes or E. coli challenge. These results indicate that TmapoLp-III may play an important role in innate immune responses against bacterial pathogens in T. molitor.

A new colored soybean variety ‘Jungmo3005’ was developed as a breeding parent. ‘Cheongjakong’ and ‘Geomjeongkong3’ were crossed in 2000. F1 and F2 populations were grown for 2 years and selected by pedigree method from F3 to F5. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2006 to 2007, and regional yield trial (RYT) in 9 regions was conducted from 2008 to 2010. ‘Jungmo3005’ is determinate, white flower, green cotyledon, green spherical seed and yellow hilum. Flowering date and maturing date were July 30 and Oct. 7, respectively. Other quantitative characteristics of ‘Jungmo3005’ were similar to ‘Cheongdu1’, but it was more tolerant to lodging and shattering than ‘Cheongdu1’ at RYT field and indoor test. Although ‘Jungmo3005’ showed symptom of mosaic disease in inoculation test at greenhouse, it had high level of resistance to soybean mosaic virus and bacterial pustule diseases at field. The yield of tofu of ‘Jungmo3005’ was more than that of ‘Cheongdu1’. The mean yield of ‘Jungmo3005’ in RYT was 256kg/10a which was 97% of the yield of ‘Cheongdu1’. ‘Jungmo3005’ is expected to be widely used as a breeding parent to cross with other varieties and lines for creating colored soybean cultivars with tolerance to lodging, shattering and bacterial pustule.

Early maturity of soybean (Glycine max (L.) Merr.) is an important character for double cultivating system with winter crops such as onion or garlic in southern area of Korea. Soybean cultivars released in the past, especially ‘Keunolkong’ was widely cultivated but it was weak at abiotic stress and low yield potential because of too short growing period and short stem height. ‘Hanol’, a new early maturing cultivar showing better abiotic stress tolerant and higher yield potential, was developed from the cross between SS91408 and ‘Hwaeomputkong’, and released in 2009. ‘Hanol’ is, compared to ‘Keunolkong’, Hanol’s growing period is five days longer and its height is 5cm higher. In addition, it showed better excess-water tolerant and 26.5g 100-seed weight. At regional adaptation yield trials (RYT) in six regions from 2007 to 2009, ‘Hanol’ showed 2.04 tons of seed per hectare, 14% higher than ‘Keunolkong’ (1.80ton/ha). ‘Hanol’ is promising for double cropping system with higher yield.

A soybean cultivar for soy-paste, ‘Hwangkeumol’, was developed from the cross between SS92414 (crossing line of ‘Pokwangkong’ and ‘Suwon163’) and ‘Hwaeomputkong’ by soybean breeding team in the National Institute of Crop Science (NICS) in 2010. A promising line, SS99409-2B-11-5-4, was selected and designated as the name of ‘Milyang202’. It was prominent and had good result from regional adaptation yield trials for three years from 2008 to 2010 and released as the name of ‘Hwangkeumol’. It has a determinate growth habit, white flower, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape and large seed (28.6 grams per 100 seeds). Maturity date of ‘Hwangkeumol’ was as early as September 15th. Therefore it is suitable for double cropping system. ‘Hwangkeumol’ was resistant to bacterial pustule and resistant to soybean mosaic virus, the major soybean diseases in Korea and tolerant to lodging in fields. The average yield of ‘Hwangkeumol’ was 2.51 ton per hectare in the regional yield trials carried out for three years from 2008 to 2010.

A soybean cultivar for soy-paste, ‘Uram’, was developed from the cross between ‘Suwon190’ and ‘SS99244’ (Shinpaldal-2 X T243) by soybean breeding team at the National Institute of Crop Science (NICS) in 2010. A promising line, SS00232-B-B-3SSD-9-4-1-1, was selected and designated as the name of ‘Milyang188’. It was prominent and had good result from regional adaptation yield trials (RYT) in southern area of Korea for three years from 2008 to 2010 and released as the name of ‘Uram’. It has a determinate growth habit, white flower, gray pubescence, yellow seed coat, yellow hilum, spherical seed shape and large seed (25.8 grams per 100 seeds). ‘Uram’ was found to be resistant to bacterial pustule and soybean mosaic virus, the major soybean diseases in Korea. The lowest pod height of ‘Uram’ was 19cm and it will be able to reduce seed loss during mechanical harvesting. The average yield of ‘Uram’ is 3.27 ton per hectare in southern double cropping area. Through these results, ‘Uram’ is soybean cultivar that is favorable for mechanization harvesting, resistant to diseases and highly yield.

Anthocyanins are very important constituent of human diet. In recent years, they have gained much attention due to their antioxidative properties. As the radish (Raphanus sativus L) has rich content of anthocyanins, the study is aimed to develop increased functional radish from selected radish varieties. ‘Bordeux’ is a hybrid variety of breeding between one accession derived from ‘Oharu’ as a maternal variety and ‘Chungpihongsim’ as a paternal variety. In this study, we investigated the new varieties of radish commonly consumed in Republic of Korea for their total phenolic content (TPC) and antioxidant activities using three (DDPH, FRAP and CUPRAC) different assays. The selected radish varieties like ‘Bordeux’, ‘Chungbok’, ‘3209’, ‘Chungwoon’, ‘Oharu’, and ‘Chungpihongsim’ were procured from the company Syngenta Korea. Among the selected radish varieties, ‘Bordeux’ (289 μg/g FW) and ‘Chungpihongsim’ (276 μg/g FW) revealed maximum amount of phenolics; whereas ‘3209’ (103 μg/g FW) and ‘Chungwoon’ (166 μg/g FW) showed the lower amount of phenolics content, respectively. Extracts from these studied radishes showed good to moderate antioxidant activities. The varieties ‘Chungpihongsim’ and ‘Bordeux’ revealed maximum antioxidant activity for all assays as demonstrated. However, some varieties like ‘3209’ and ‘Oharu’ exhibited the lowest antioxidant activity in all the tested assays, viz; DPH, FRAP and CUPRAC in μg TE/g FW, respectively. The antioxidant activities may be attributed to the higher phenolic acid contents as a linear relation was observed between the two components and the antioxidant parameters.
