A new adzuki bean cultivar, ‘Hongchan’ (Vigna angularis (Willd.) Ohwi & H. Ohashi), with a bright red seed coat and large seed size was developed through a pedigree selection by crossing ‘YA0814’ and ‘Milyang9’ from 2009 to 2022. A promising line, ‘YA0912-B-B-6-1-3-3-1-2,’ was selected and designated as ‘Milyang50. ’ From 2020 to 2022, regional yield trials (RYTs) were conducted in four locations (Miryang, Iksan, Cheongju, and Chuncheon). This line demonstrated stable performance and was released under the name ‘Hongchan.’ It has a semi-determinate growth habit, green embryonic color, green stems, yellow flowers, yellow pods, and a white hilum. It is late-maturing, but flowers early; its flowering and maturing dates were August 10 and October 9, respectively, which were 10 days earlier in flowering and 5 days later in maturity than ‘Arari.’ The stem height, number of pods per plant, and number of seeds per pod were 56, 24, and 6.5, respectively. There were significant differences (p<0.05) in the L*, a*, and b*values of the seeds and pastes of ‘Hongchan’ and ‘Arari.’ The average 100-seed weight of ‘Hongchan’ was 21.3 g, which was 4.9 g heavier than that of ‘Arari.’ The average yield of ‘Hongchan’ was 2.11 ton/ha, which was 6% higher than that of ‘Arari’ in the 3-year regional yield trial. These results indicate that ‘Hongchan’ is an adzuki bean cultivar suitable for mechanical harvesting and paste processing (Registration No. 5573).

The global seed distribution market is rapidly transforming into a high-value-added seed market, with the production and distribution of processed seeds expanding, led by multinational seed companies. However, domestic seed companies still lack investment in seed processing, and the level of technology for processing distributed seeds is relatively low. The proportion of seeds processed and produced by seed companies must be increased to transform the domestic seed industry into an internationally competitive export industry. According to the results of a survey of 2,679 domestic companies by the National Seed and Variety Service (2021), the main business field of seed companies is seed production (1,192 companies), followed by seed sales (1,041 companies), nurseries (328 companies), and seed processing (35 companies). In conclusion, few companies conduct business in the field of seed processing. Accordingly, the government plans to build seed-processing facilities for joint utilization by seed companies to expand the supply of high-quality seeds from domestic seed companies. To this end, we investigated the seed- processing status of major seed companies and conducted a demand survey for facilities and equipment in the seed-processing field. Details and operational plans for the establishment of a tentatively named ‘Seed Enterprise Joint Utilization Seed Processing Center,’ based on domestic companies' processing status and demands, are presented in this paper.

Oats are known for their abundance of quality proteins and lipids compared to those of other grain crops; they especially contain a large amount of good quality fibers, including β-glucan. The Korean domestic consumption of oats is rapidly increasing due to their high nutritional value. However, the research for functional food breeding material has been insufficient because oats have been focused on as feed. Therefore, this study aimed to evaluate the agronomic traits and important nutritional ingredients, including β-glucan, protein, lipid, fiber, and dietary fiber, of 142 oat germplasms from Korea, China, and Japan, which are maintained in the National Agrobiodiversity Center. In addition, the diversity by origin of the germplasms was analyzed based on their agronomic traits. For the agronomic characteristics, Korean oat germplasms were on average headed and matured earlier than the Chinese and Japanese ones. Seven accessions, including IT151107, were matured before mid-June, which makes double cropping possible in the Southern region of Korea. In the diversity analysis by origin based on quantitative agronomic traits, Korean oat germplasms were in the distinguished group compared to Chinese and Japanese germplasms. Oat germplasm had a wider range of main ingredients compared to that of Korean domestic oat cultivars. However, Chinese germplasms had a significantly higher β-glucan content, while Korean germplasms had significantly higher crude protein, crude lipid, and crude fiber contents, than did other germplasms from other origins. Dietary fiber contents showed no significant differences between origins. IT129802 (China), IT166594 (Korea), IT166584 (Korea), IT151108 (Korea), and IT129798 (China) showed the highest β-glucan, protein, lipid, fiber, and dietary fiber contents, respectively. These selected oat germplasms can be superior breeding materials for various functional and agronomic purposes.

Consumption of oat-based food is rapidly increasing due to consumer preference for functional foods. Until now, breeding is focused on the development of naked oat for food in Korea. Hulled oats recognized as forage have strong merits for yield and stability in cultivation except milling properties. Lately, advanced milling technology provides an opportunity to use hulled oats for food. Therefore, the processing characteristics of hulled oats are of great importance for food use. This study examined the physicochemical properties and dietary fiber of 9 Korean oat cultivars (4 hulled oats as compared with 5 naked oat cultivars). Findings showed that the color values (i.e. L and W) of hulled oat cultivars in seed and flours are lighter than the naked oats. The protein and ash contents are higher in hulled oats as compared with naked oats. The unsaturated fatty acid (USFA), mainly C18:1, C18:2 were 80~83%. USFA of ‘Daeyang’ (DY, naked) and ‘Jopung’ (JP, hulled) were 82.0 and 81.9% respectively. Total Dietary fiber and Total β-Glucan contents ranged from 13.2 to 20.6% and from 3.4 to 4.1% in oat flours. The ‘DY’ (4.10%, naked), ‘JP’(4.09%, hulled) and Highspeed (4.07%, hulled) showed high levels of β-Glucan contents. Findings of the study will provide useful information in extending the use of hulled oats for food.

The influence of seed maturity, stratification, and seed washing method on seed germination were investigated for establishment of seed propagation system in dropwort (Oenanthe stolonifera DC). Seed germination rate was increased as period of the seed ripening increased, especially the seed over 40 days after flowering showed the highest germination rate. The optimum period of cold stratification treatment to promote seed germination was about 8 weeks. The seed treated by a cold wet stratification with sand exhibited higher germination rate compared to the seed treated by a cold wet stratification without sand. The stratified seeds that were stored in the ground having fluctuating temperature were improved up to 19%, while stratification stored under constant temperature(4°C) did not improve germination rate. In addition, 8 weeks of stratification period under fluctuating temperature in the ground was most effective. Sodium hypochlorite, vital oxide, and distilled water were used as chemicals to remove the germination inhibitor of seed coat. Water washing of seed coat after soaking in 0.5% sodium hypochlorite and 0.0005% vital oxide for three minutes and 60 minutes respectively could effectively remove the germination inhibitors in the seed coat.

DOI: https://doi.org/10.9787/KJBS.2014.46.3.323

A new naked oat (Avena sativa L.) cultivar ‘Suyang’ was developed by National Institute of Crop Science, RDA in 2010. It was derived from the cross between ‘Sikyonggwiri’ and ‘Gwiri23’. Subsequent generations were handled in a bulk method and pedigree selection program, and ‘SO96025-B-303-44-2-4’ was selected for agronomic appearance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, being designated as ‘Gwiri56’. The ‘Gwiri56’ was subsequently evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2010 and was released as the name of ‘Suyang’. ‘Suyang’ had 11 days earlier heading date and 6 days earlier maturing time than the check cultivar ‘Seonyang’ in field condition. The ‘Suyang’ had 23.7 cm of spike length, 568 spikes per m2, 73 grains per spike, 29.2 g of 1,000-grain weight, and 646 g of test weight. ‘Suyang’ showed better winter hardiness than that of the check cultivar ‘Seonyang’, and similar seed quality to the check cultivar in respect to crude protein (11.3%) and β-glucan content (4.7%). However, it showed higher husking rate than that of check cultivar. The grain yield of ‘Suyang’ in the regional yield trial for 4 years was averaged 4.35 MT ha-1, which was 29% higher than that of the check cultivar ‘Seonyang’. ‘Suyang’ is recommended for fall sowing cropping only in the south area where daily minimum mean temperatures are averaged higher than -4°C in January.
