China is a one of the largest agricultural countries in the world. China consumes around 12.5 billion kilograms of seeds each year. Suchhuge demand for seeds has made the Chinese seed market more and more attractive for investment. Through analysis on the present situation and existing problems of the seed industry in China and based on the current Chinese seed industry development, some future prospects for investments are indicated. This investigation was carried out to propose the appropriate strategies on the development of the Korea seed industry as it considers its entry into the China seed market as a new growth engine in the agricultural sector. The basic law regulating the Chinese seed industry is the PRC Seed Law that generally refers to the protection of germplasm resources, verification of varieties, seed quality issues, the import and export of seeds, seed administrative management, and various rights and obligations. The regulations were aimed at the protection of the rights concerning new varieties of plants. China has two main industry associations, the National Seed Association and the China Seed Industry IP Union, that are non-profit associations consisting of entities and people engagin in the seed scientific research, production, operation and management. The China National Seed Group Co., Ltd. (“Sino Seeds”) is the market leader in China regarding the seed industry. The chinese government, however, encourages investment from multinational companies as well as importation of modern crop planting management technologies and equipment. It supports the entry of investors with proven experiences in breeding and germplasm resources expansion and R&D. There has never been a better time for multinational companies with proven seed industry experience to look at building relationships with the Chinese government and enterprises.

Isoflavone contents in soybean seeds are affected by both genetic and environmental factors. Correlation analysis between these factors and isoflavone contents are considered as valuable inputs when breeding improved soybean cultivars. In this study, the seeds of 49 soybean accessions grown in Korea were grouped as black, yellow, green, yellowish-green, pale yellow, and green with a black spot based on their seed coat colors. The contents of 12 isoflavones were analyzed and the association between isoflavone content and seed coat color was determined. The accessions were also grouped as early, intermediate, and late-maturing based on their days to maturity. Out of the 12 isoflavones, 11 were found in 2 accessions, 9 in 18 accessions, 8 in 11 accessions, 7 in another 11 accessions, and 6 in 7 accessions. The total isoflavone content (TIC) in black, yellow, green, yellowish-green, pale yellow, and green with black spot soybeans was in the ranges 2.110 ~ 5.777, 2.487 ~ 4.733, 2.185 ~ 4.413, 2.681 ~ 4.065, 1.827 ~ 4.085, and 3.376 ~ 4.133 ㎎/g, respectively. The average TIC was highest in green with black spot soybeans (3.616 ㎎/g), and lowest in pale yellow soybeans (2.875 ㎎/g). Besides, the average TIC was lowest in early maturing accessions compared to late- and intermediate-maturing accessions. TIC was strongly correlated to malonylgenistin (r = 0.91) and malonyldaidzin (r = 0.78) contents, and poorly correlated to glycitein (r = 0.04) and malonylglycitin (r = 0.18) contents. Also, days to maturity showed strong correlation with malonylgenistin (r = 0.47) content and TIC (r = 0.38). The principal component analysis outlined accessions with high TIC and diverse isoflavones along the first and second components, respectively. The results of the present study depicted that green soybeans with a black spot could be sources of high TIC. Furthermore, late-maturing accessions with diverse isoflavones in their seeds could be useful in future agricultural systems in Korea.

Pigeon pea (Cajanus cajan) is an important legume species that produces seeds that are rich in phenolic compounds and dietary nutrients. The aim of the present study was to evaluate the agricultural characters, phenolic and nutritional contents, and antioxidant capacities of seeds from 82 pigeon pea germplasms cultivated in the Republic of Korea. The accessions exhibited compact (24.39%), semi-spreading (74.39%), or spreading (1.22%) growth habits and determinate (89.02%), indeterminate (8.54%), or semi-determinate (2.44%) flowering patterns. Days to 75% maturity ranged from 30 to 72 d, and yield per plant ranged from 6.00 to 148.60 g. Meanwhile, total phenolic, crude protein, crude fiber, and dietary fiber contents ranged from 16.42 ± 0.62 to 29.67 ± 0.43 ㎎ gallic acid equivalent per g of dried extract, from 16.76 ± 6.74% to 22.61 ± 0.05%, from 4.70 ± 0.24 to 8.63 ± 0.02%, and from 12.98 ± 0.71 to 33.19 ± 1.50%, respectively. In addition, DPPH radical-scavenging capacity ranged from 1.61 ± 0.10 to 16.04 ± 2.30 ㎎ ascorbic acid equivalent per g of dried extract, and Trolox equivalent antioxidant capacity ranged from 3.03 ± 0.86 to 42.24 ± 0.72 ㎎ Trolox equivalent per g of dried extract. Phenolic content was correlated with both DPPH radical-scavenging capacity (r = 0.63) and Trolox equivalent antioxidant capacity (r = 0.29). Nine accessions (IT170290, IT170291, IT170270, IT170276, IT170379, IT170386, IT170388, IT170418, and IT170340) exhibited early maturity, compact and erect growth habits, and above average antioxidant activities and phenolic and protein contents. In addition, accessions IT170290 and IT170291 were especially promising pigeon pea germplasms to grow, owing to various favorable characteristics (e.g., high yield and dietary fiber content). Hence, these accessions could be useful cultivars to the Republic of Korea if considered in future agricultural systems.

In crop breeding program, information about genetic dissimilarity on breeding resources is very important to corroborate genealogical relationships and to predict the most heterozygotic hybrid combinations and inbred breeding. This study aimed to evaluate the genetic variation in Kenyan sunflower breeding lines based on simple sequence repeat (SSR). A total of 83 alleles were detected at 32 SSR loci. The allele number per locus ranged from 2 to 7 with an average of 2.7 alleles per locus detected from the 24 sunflower accessions and the average value of polymorphic information contents (PIC) were 0.384. A cluster analysis based on the genetic similarity coefficients was conducted and the 24 sunflower breeding resources were classified into three groups. The principal coordinates (PCoA) revealed 34% and 13.38% respectively, and 47.38% of total variation. It was found that the genetic diversity within the Kenyan sunflower breeding resources was narrower than that in other sunflower germplasm resources, suggesting the importance and feasibility of introducing elite genotypes from different origins for selection of breeding lines with broader genetic base in Kenyan sunflower breeding program.

In Korea, common and Tartary buckwheat are cultivated mainly in spring and fall, however the available buckwheat varieties are still very limited. In this study, we have evaluated buckwheat germplasm for agronomic traits and compared flavonoids contents in different cultivation period and collection area. In common buckwheat, the number of days from sowing to flowering was 40 and 31 days and from sowing to maturity took 90 and 69 days in spring and fall cultivation, respectively. The number of nodes and branches were higher in spring cultivation while the hundred seed weight was higher in fall cultivation. The average flavonoids contents in common buckwheat were 0.20 ㎎/g dry weight (DW) and 0.40 ㎎/g DW in spring and fall cultivation, respectively. The highest flavonoids content was detected in Jeonnam accessions with 0.29 ㎎/g DW and 0.43 ㎎/g DW during spring and fall cultivation, respectively. The flavonoids contents were varied from 1.5 to 2.5 times according to the collection area. These results suggest that the agronomic traits and flavonoids contents were vary depending on the cultivation environment and germplasm collection area. Therefore, it is necessary to select the material by considering the characteristics of the germplasm for breeding of new varieties.

A total of 447 accessions consisting of seven Brassica spp.; Brassica carinata (34), B. juncea (199), B. rapa subsp. dichotoma (18), B. rapa. subsp. oleifera (14), B. rapa subsp. rapa (36), B. rapa subsp. trilocularis (56) and B. alba subsp. alba (90) were studied for their morphological characters and fatty acid compositions. There was a wide variation for morphological traits, oil content and fatty acid composition among Brassica species. Seed number/silique and yield/plant were varied from 4.2 (B. alba) to 25.1 (B. rapa subsp. trilocularis) and from 170.7 g (B. rapa subsp. oleifera) to 351.9 g (B. juncea L. Czern.), respectively. Among Brassica species, B. rapa subsp. trilocularis exhibited the highest oil (29.2%), stearic (20.4%) and erucic acid (45.3%) content. B. carinata had the highest content of palmitic (5.2%), oleic (21.2%) and linolenic acid (11.1%). B. rapa subsp. dichotoma and B. rapa subsp. oleifera exhibited the highest content of linoleic (8.1%) and behenic (26.9%) acid, respectively. B. rapa subsp. trilocularis exhibited the highest (45.3%) erucic acid content and significant positive relationship was observed between oleic acid and linoleic acid. This variation of agronomic and fatty acid compositions in Brassica species can be utilized to develop new varieties.

Rice blast, caused by a fungus Magnaporthe oryzae, is one of the most devastating diseases of rice worldwide. Analyzing the valuable genetic resources is important in making progress towards blast resistance. Molecular screening of major rice blast resistance (R) genes was determined in 2,509 accessions of rice germplasm from different geographic regions of Asia and Europe using PCR based markers which showed linkage to twelve major blast R genes, Pik-p, Pi39, Pit, Pik-m, Pi-d(t)2, Pii, Pib, Pik, Pita, Pita/Pita-2, Pi5, and Piz-t. Out of 2,509 accessions, only two accessions had maximum nine blast resistance genes followed by eighteen accessions each with eight R genes. The polygenic combination of three genes was possessed by maximum number of accessions (824), while among others 48 accessions possessed seven genes, 119 accessions had six genes, 267 accessions had five genes, 487 accessions had four genes, 646 accessions had two genes, and 98 accessions had single R gene. The Pik-p gene appeared to be omnipresent and was detected in all germplasm. Furthermore, principal component analysis (PCA) indicated that Pita, Pita/Pita-2, Pi-d(t)2, Pib and Pit were the major genes responsible for resistance in the germplasm. The present investigation revealed that a set of 68 elite germplasm accessions would have a competitive edge over the current resistance donors being utilized in the breeding programs. Overall, these results might be useful to identify and incorporate the resistance genes from germplasm into elite cultivars through marker assisted selection in rice breeding.

This study was investigated to develop mass evaluation system for the contents of crude protein, oil and fatty acid in soybean germplasm using NIRS. NIRS equations were created with 345 soybeans, multiple correlation coefficients of crude protein, oil, palmitic, stearic, oleic, linoleic and linolenic acid between data obtained from NIRS and quantitative analysis were 0.983, 0.969, 0.592, 0.514, 0.978, 0.961 and 0.957, respectively. Equation statistics indicated that contents of crude protein, oil and unsaturated fatty acid except palmitic and stearic acid in soybean seed were suitable for determination by NIRS. Those NIRS equations were applied to examine crude protein, oil and unsaturated fatty acid of 854 soybean landraces from Korea. The average contents and ranges of crude protein and oil were 39.2% with a range of 33.7-47.0% and 15.0% with a range of 9.8-20.3%, individually. In addition, those of oleic, linoleic and linolenic acid were 21.4% with a range of 12.1-30.2%, 55.6% with a 47.8-62.3% and 8.1% with a range of 5.9-10.7% respectively. We conducted quantitative analysis to reconfirm with IT154552 (45.1%) and IT023955(46.9%) above 45% of crude protein, the results were similar from NIRS (45.2%, 47.0%). NIRS data for protein from this study made no difference with lab data, which would be useful for mass evaluation. There was negative correlation (-0.203) between crude protein and oil, positive correlation (0.379) between crude oil and oleic acid, and significantly negative correlation (-0.879) between oleic and linoleic acid.

Low temperature germinability (LTG) is an important trait for breeding of varieties for use in direct-seeding rice production systems. Although rice (Oryza sativa L.) is generally sensitive to low temperatures, genetic variation for LTG exists and several quantitative trait loci (QTLs) have been reported. The objective of this study was to develop and employ high-efficiency molecular markers for evaluation of LTG in rice germplasm. A panel of japonica rice accessions (n=180) from temperate regions in Asia was evaluated for LTG and genotyped with markers from regions previously reported to harbor other LTG QTLs. ANOVA revealed that four markers on chromosome 2, 4, and 11 from previously reported QTLs showed highly significant value (p < 1.0e-04) and their R2 ranged 0.083 (qLTG11-1) to 0.190 (qLTG4b-1). An association analysis was conducted using SNP data generated by sequencing of the panel. Eight SNP markers were found to be significantly associated with LTG using general and mixed linear models. Three SNP-based CAPS and dCAPS markers from these results were developed and showed higher accuracy in predicting sensitive LTG germplasm. These new LTG markers will be useful for molecular evaluation of germplasm, particularly to identify sensitive or weak LTG accessions.

This experiment was carried out to compare the morphological traits of Korean, Chinese, Japanese and Southeast Asian(SEA) soybeans from RDA genebank. Days to flowering were ranged from 51 to 125 days with an average of 75 days. Those of China were the shortest with an average of 58 days and those of SEA were the longest with an average of 99 days. Growth days were the shortest with 94 days from China, and longest with 188 days from Korea and SEA. The 100 seed weight of soybeans was ranged from 3.4g to 46.4g, with an average 22.2g. The 100 seed weight was the lightest with an average 11.8g from SEA and the heaviest with an average 24.6g from Korea. In growth habit, over 50% of being collected from Korea, Japan and China were erect type, but 94% from SEA were intermediate type. The highest percentage of seed coat color was yellow(66.1%), followed by yellowing green(10.0%). As a result of cotyledon color in 760 black seed was 76.1% with yellow, 23.9% with green. Green cotyledon was much more in Korea(38.6%) and Japan(33.3%) than other countries. One thousand seven accessions from Korea, Japan, China and SEA were analyzed using 7 SSR markers. One hundred eighty alleles were detected with a lowest 16 at the Satt537 and a highest 35 at the Satt390. The average polymorphism information content(PIC) was 0.68, the highest with 0.7 in Japan. Gene diversity was the highest with 0.73 in China and Japan, while the lowest in SEA with 0.68.

Among the diverse crops, rice (Oryza sativa L.) has been domesticated as a staple carbohydrate sources mainly in Asia region, and RDA Genebank at the National Agrobiodiversity Center (NAAS) has conserved about 37 thousand rice accessions accordingly. Seed dormancy, one of domesticated traits, prevents pre-harvest sprouting (PHS) which causes degradation of grain quality in cereal crop. In previous study, we surveyed the variation of seed germinability of diverse 200 rice germplasm and detected the three distinguished groups besides admixed types; the first group (G-1) revealed high germinability at harvesting time, and the second group (G-2) and third group (G-3) acquired high germnability subsequent to after-ripening and dormancy breaking process, respectively. To reduce environmental effects on detected variation of germinability, we selected representative 14 accessions which have similar heading date of each group and measured the degree of PHS using freshly harvested panicles. Variation of PHS showed similar tendency of germinability group; generally, high PHS for G-1, low PHS for G-2 and no PHS for G-3. To resolve genetic and physiological factors concerning on PHS and seed dormancy, we checked the change and variation of ABA known for critical regulator for seed dormancy, and high PHS accessions interestingly revealed high ABA content in 10 DAF. Based on these study, we plan to analyze genetic factors affecting the degree of seed germinability and PHS.

Soybean (Glycine max L.) is crucial legume crop as source of high quality vegetable protein and oil, and Korea is regarded as a part of center of soybean origin. To expand the information of conserved genetic diversity, we analyzed the genetic variability of soybean collection mainly introduced Korean accessions using 75 microsatellite markers. A total of 1,503 alleles with an average value of 20.0 alleles were detected among 644 accessions. Korean collection revealed average allele number of 13.4 while Chinese, Japanese and Southeast Asian accessions showed 9.0, 5.4 and 6.5 mean alleles, respectively. Especially, Korean accessions showed more number of private allele per locus as 3.4 contrary to other geographical groups. The mean expected heterozygosity and polymorphic information content was 0.654 and 0.616, respectively, and expected heterozygosity values were not significantly distinguished according to the geographical groups. The phylogenetic dendrogram and deduced population structure based on DNA profiles of 75 SSR loci showed Korean accessions formed distinct gene pool against Chinese accessions, and could be divided into five subpopulations. Korean soybean accessions have specific genetic diversity and might be serve the valuable alleles for bio-industry as a part of the center of soybean origin.

본 연구는 농업유전자원센터에 보존 되어있는 콩 유전자원 중 한국 재래종 자원 880점을 대상으로 농업적 특성을 조사하고, 분자마커를 이용하여 유전적 다양성을 분석하였으며 결 과는 다음과 같다. 1. 개화일수는 51∼104일, 평균 74.4일이었으며 성숙일수는 28∼106일, 평균 72.2일이었고 생육일수는 101∼188일, 평균 146.6일이었다. 지역별 평균 개화일수는 강원지역이 69.5일로 가장 짧고, 제주지역이 77.9일로 가장 길었다. 또한 평균 생육일수는 강원지역이 평균 140.6일로 가장 짧고, 제주지역이 152.8일로 가장 긴 것으로 나타났다. 대조품종의 생육일수는 태광콩 133일, 대원콩 143일, 일품검정콩 129일, 풍산나물콩 146일과 비교하였을 때 중만생종인 태광콩보다 생육일수가 길어 우리나라 재래종에 만생종이 많음을 알 수 있었다. 2. 100립중의 범위는 4.3∼46.4 g이며, 평균 26.1 g이고, 립중별 분포는 대립종의 비율이 39.2%로 가장 많고, 중립종 30.8%, 극대립종 17.5%, 소립종 8.8%, 극소립종 3.8% 순으로 중립종 이상의 비율이 87.5%로 대부분이었다. 3. 종피색은 검정색의 비율이 52.4%로 가장 많았고, 황색 28.5% 순이었다. 지역별로는 경남지역 수집자원은 황색종피 비율이 높고, 제주지역은 황색, 녹색, 검정색의 비율이 유사하였으며, 경기지역은 녹색종피의 비율이 28.8%로 황색종피보다 많았다. 4. 검정콩 460점을 대상으로 자엽색 조사 결과 황색이 59.7%, 녹색이 40.1%이었다. 자엽색의 지역별 분포는 매우 커서 제주와 경남지역은 녹색 자엽비율이 각각 83.3%와 62.7%로 황색 자엽보다 월등히 많았으며, 전북과 전남지역의 녹색자엽 비율은 각각 5.7%와 13.8%로 극히 낮아 지역별 차이를 보였다. 5. 기초특성 평가 자원중 350점에 대해 7개의 SSR 마커를 이용하여 프로파일링한 결과 총 110개의 대립인자(allele)가 확인되었으며 각 유전자좌별로 대립인자수는 10개에서 26개 평균 15.7개였다. 유전적 다양성(PIC)은 0.711로 비교적 높았으며, 각 유전자좌별 allele의 수는 경북지역이 9.7로 가장 많고, 유전적 다양성은 제주가 0.693으로 가장 높았다.
