‘Migamjosaeng’ (Diospyros kaki Thunb.) is a new pollination-variant non-astringent type (PVNA) persimmon cultivar developed by Sweet Persimmon Research Institute of Gyeongnam Agricultural Research & Extension Services. This cultivar was selected among the seedlings obtained from the cross between ‘Mazumotowase-Fuyu’ and ‘Nishimurawase’ in 1995. The seedlings were cultivated from 1996 to 2001 and ‘Migamjosaeng’ was selected in 2002. The tree growth habit and fruit characteristics of ‘Migamjosaeng’ were investigated from 2004 to 2007. The tree growth habit was moderate vigor and showed spreading shape. Flowers bloomed only in female flowers. The flowering time was similar to that of ‘Nishimurawase’ (control) in late May, but the harvest time was about 3 days earlier than ‘Nishimurawase’ in late September. ‘Migamjosaeng’ is characterized by its beautiful orange skin color with round flat shape of fruits. Average fruit size was about 160g. Soluble solids were 16.6°Brix and higher than that of control (14.5°Brix), which contributed to its excellent tastiness. It was noteworthy that occurrence of calyx-end cracked fruits and striped fruit was very rare compared with the control. Therefore, ‘Migamjosaeng’ trees produced marketable fruits much higher than the control tree. Flesh firmness was slightly high and similar to ‘Nishimurawase’.
“蜜果生”(Diospyros kaki Thunb.)是庆南农业研究推广院甜柿子研究所开发的授粉变异无涩味型(PVNA)柿子新品种。本品种选育自1995年‘maszumotowase - fuyu’与‘Nishimurawase’杂交获得的幼苗。从1996年到2001年进行了栽培，并于2002年选定了“密姜草生”。2004 ~ 2007年，对“蜜甘乔生”的生长习性和果实特性进行了调查。树木生长习性中等，活力适中，呈平展状。花儿只开雌花。5月下旬开花时间与对照“西村濑”相近，但9月下旬收获时间比“西村濑”早3天左右。“蜜柑生”的特点是表皮呈美丽的橙色，果实呈圆形。平均果实大小约为160克。可溶性固溶体的糖度为16.6°，高于对照(14.5°糖度)，口感极佳。值得注意的是，与对照相比，花萼端裂果和条纹果的发生非常罕见。因此，与对照树相比，“蜜柑生”树的可销售果实要高得多。肉质紧致度略高，与“西村濑”相似。

It is important for radish to have late flowering characteristics especially in the case of spring and winter cultivars. To understand late flowering characteristics of radish at the molecular level the flowering time genes of two radish lines (NH-JS1 and NH-JS2) with different flowering time were compared by re-sequencing their genomes. There were a total of 872,587 SNPs and 194,637 INDELs between the two lines. The SNP density of each chromosome was relatively uniform throughout, but the region with low SNP density was found at the end of R3 and the middle of R9. To compare the flowering time genes of the two lines, we first looked for the flowering time genes in radish using Arabidopsis thaliana flowering time genes. As a result, homologs of radish were found for most flowering time genes, but FRIGIDA was not found. Among 224 radish flowering time gene-homologs found, 97 genes showed more than one sequence difference (SNP or INDEL) between the two lines, and 127 genes had no difference. In particular, no sequence differences were found in FT, CO, and FLC, core flowering time control genes. Rs350520 (FVE), Rs193800 (CURLY LEAF) and Rs255320 (ATX1) with more than 100 sequence variations were expected to have a significant effect on flowering time difference between the two lines. These results will be of great help in understanding the flowering timing difference between the two lines at the molecular level.

: To diversify the grain size and shape of japonica rice, we developed the Breeding Materials with Diverse Grain Size and Shape (BM_DGS) and characterized the grain and yield-related traits. We used the donor parents Jizi1560 and Jizi1581, japonica germplasm with extremely large grain size. Four cross combinations between the each donor parents and Korean high yielding japonica rice cultivars, Deuraechan and Boramchan, were constructed and anther culture method was applied. Among 290 doubled haploid lines, we selected 91 elite lines with diverse grain size and shape and designated to the BM_DGS. The grain size and shape of BM_DGS exhibited beyond the characteristics of previously developed Korean rice cultivars. The alleles of major grain-related genes, GW2 , GS3 , and qSW5 , in BM_DGS showed two types, wild type or loss-of-function mutant type. The loss-of-function mutant alleles, gw2 , gs3 , and qsw5 , had an effect on increasing grain size. The phenotypic variation of grain length was mostly controlled by GS3 alleles, and grain width and thickness were influenced by the combinations of GW2 and qSW5 alleles. 1,000-grain weight was determined by the combinations of GW2 , GS3 , and qSW5 . The grain-related genes influenced the phenotypic variation of yield-related traits. The result of this study could be useful to elucidate the relationship between the grain-related genes and agronomic traits. And the BM_DGS are being utilized in the breeding programs to diversify the grain size and shape in japonica rice.

‘Pungwonmi’, a new sweetpotato variety, was developed for table use by Bioenergy Crop Research Institute, National Institute of Crop Science (NICS), RDA in 2014. This variety was derived from the cross between ‘Benisatsuma’ and ‘Luby3074’ in 2006. The seedling and line selections were performed from 2007 to 2009, and preliminary and advanced yield trials were carried out from 2010 to 2011. The regional yield trials were conducted at five locations from 2012 to 2014, and it was named as ‘Pungwonmi’. This variety has cordate leaf shape, and its leaves, stems, nodes, and petioles are green. Storage root of ‘Pungwonmi’ has an elliptical shape, red skin, and light orange flesh. ‘Pungwonmi’ was moderately resistant to fusarium wilt, and resistant to root-knot nematode. Dry matter content was 31.2%, and texture of steamed storage root was intermediate. Total sugar content of raw and steamed storage roots of ‘Pungwonmi’ was higher than that of ‘Yulmi’. β-carotene content of ‘Pungwonmi’ was 9.1 mg/100g DW. Yield of marketable storage root over 50 g of ‘Pungwonmi’ was 24.3 MT/ha under the early season culture, which was 46% higher than that of ‘Yulmi’. The number of marketable storage roots per plant was 2.8 and the average weight of marketable storage root was 156 g under the optimal and late season culture. Marketable storage root yield of ‘Pungwonmi’ was 24.1 MT/ha under the optimum and late season culture, which was 26% higher than that of ‘Yulmi’. (Registration No. 6428).

We developed new two-rowed covered barley ‘Gwangmaeg’ superior to ‘Hopum’ that has been widely cultivated in Korea for using beer-materials. ‘Gwanngmaeg’ was related from the line named as ‘Iksan149’ in 2010 after yield trials test in conducted for three years from 2008. And then it was registered to ‘Plant protection right, No. 5847’ in 2016 after field experiment by KSVS(Korea Seed & Variety Service). ‘Gwangmaeg’ has distinct characteristics in winter type (IV) and mid-tall culm length which makes reduce damage by off-season heading and lodging comparing to those of ‘Hopum’. ‘Gwangmaeg’ have characteristics of cold tolerance and disease resistance to BaYMV(Barley yellow mosaic virus) and Net blotch(Pyrenophora teres). Yield of ‘Gwangmaeg’ was about 611kg/10a and 524kg/10a in upland and paddy field condition, respectively, which higher 2-4% than ‘Hopum’, however, it has no significant difference. In quality examination for beer usage, ‘Gwangmaeg’ has lager grain and higher assortment ratio than those of ‘Hopum’. In malt quality, ‘Gwangmaeg’ showed higher and better quality in malt extract rate and diastatic power than those of ‘Hopum’. ‘Gwangmaeg’ would be suitable for the area above –4°C of daily minimum temperature in January in Korean peninsula.

Knowledge of the chromosomal constitution of the ancestors of modern soybean will complement plant breeding efforts to improve agronomic and economic characteristics of soybean. Variation block (VB)-based comparison using genome-wide insertion/deletion (InDel) markers was used on a diverse panel of 147 soybean cultivars to assess the impact of chromosomal changes during modern breeding. There were identical variation patterns of the examined InDels consistently appearing in the genome parts arising from parental varieties, indicating that soybean chromosomes in descendants should be all determined by genetic reshuffling of VBs inherited from parental chromosomes. Structure analysis of the accessions through the 202 InDels separated the accessions into four subgroups. Gene introgression revealed by the structure analysis agreed with the fact that a limited number of landraces and elite varieties were introduced and used as donors for breeding soybean cultivars in pedigree analysis. Especially, VBs became more reshuffled over time as a result of the breeding process, which resulted in using breeding parents with new VB-types for improving the end-use value of soybean. Therefore, their clustering using the 202 VB-specific InDels is strongly influenced by the difference in breeding ancestors among the subgroups. This indicates that the 202 InDel markers are very useful for genetic study by analyzing the reshuffling patterns of the parental genomes in the descendant.

‘Hyangdreamchal’, a new early maturing, aromatic and glutinous rice variety was developed by the crop breeding team of Crop Research & Development Division, GARES, Hwaseong, Korea in 2012. ‘Hyangdreamchal’ was derived from a cross between ‘Jinbuchal’ and ‘Miyakaori’ in 2001. This variety headed on July 28 which was 14 days earlier than ‘Hwaseongbyeo’ in Gyeonggi Province. It showed resistance to lodging with strong culm. It's culm length and panicle length were 71 cm and 20 cm, respectively. This variety has 13 tillers per hill and 92 spikelets per panicle. It was medium grain variety and 1,000 grain weight of brown rice was 20.1g. Its cold tolerance was stronger than ‘Hwaseongbyeo’ however it was susceptible to blast virus disease, bacterial leaf blight and insect pest. The milled rice of ‘Hyangdreamchal’ had a glutinous and aromatic endosperm. The yield potential of ‘Hyangdreamchal’ in milled rice was 4.15 MT/ha under the ordinary culture of the local adaptability test in 4 areas of Gyeonggi Province for three years. This variety would be adaptable to the Gyeonggi Province. (품종보호번호 : 제5568호)

‘Manbaek’ is a bacterial blight resistant mid-late maturing rice cultivar with high grain quality. ‘Manbeak’ was derived from anther culture using the backcross combination, Hopum*2/SR30075. ‘Hopum’ is a mid-late maturing rice cultivar with high grain quality and ‘SR30075’ is a pyramid line carrying three bacterial blight resistance genes. ‘Manbaek’ was selected through the pedigree method, yield trials, and local adaptability tests. ‘Manbeak’ carrying two bacterial blight resistance gene Xa3 and xa5 showed high-level and broad-spectrum resistance against bacterial blight. ‘Manbaek’ was resistant to K3a, mostly virulent race in Korea, and exhibited resistance reaction against 16 Korean bacterial blight isolates. ‘Manbaek’ was a mid-late maturing rice. The heading date of ‘Manbaek’ was August 19th, which was 5 days later than that of ‘Nampyeong’. Manbaek’ was a lodging-tolerant rice with short culm and dark green leaf. Due to the low viviparous germination, ‘Manbaek’ could be a useful material to prevent pre-harvest sprouting. ‘Mabeak’ was resistant to bacterial blight and rice stripe virus, but susceptible to other virus diseases and insect pests. The yield of ‘Manbaek’ was similar to ‘Nampyeong’. ‘Manbaek’ showed excellent grain appearance and good tastes of cooked rice, so that it could contribute to improving the quality of bacterial blight resistant cultivars. ‘Manbaek’, bacterial blight resistant cultivar with high grain quality, is suitable for the cultivation at bacterial blight prone area and has been utilized in the breeding programs for enhancing the resistance against bacterial blight (Registration No. 6069).

Kimchi cabbage (known as Chinese cabbage) is major vegetable in Korea. An inbred line of ‘Wonkyo20038ho’, was developed by the National Institute of Horticultural & Herbal Science, RDA in Republic of Korea. The microspore culture was carried out using ‘Chunhuigohangwang’ which was introduced from China in 2002. Among 3 DH inbred lines, ‘Wonkyo20038ho’ inbred line was finally selected after field exhibition in 2009. The horticultural traits of ‘Wonkyo20038ho’ inbred line; half-open head, white inner leaf colour, and dark green outer leaf colour. The average (for four years) head weight was 2025.3g, and head width and height were 15.8cm and 32.4cm, respectively. Head shape was narrow elliptic and degree of overlapping leaf was medium. Numbers of outer and internal leaves were 14.1 and 49.8, respectively. Harvest maturity was mid-late maturing type and average of seed yield for five years was 926 seeds. In addition, ‘Wonkyo20038ho’ inbred line is suitable for salad in that it possessed few trichome and narrow elliptic head shape.
