Wheat, in conjunction with rice and maize, constitutes one of the three most significant staple crops worldwide, sustaining over 40% of the global population. In Korea, the annual per capita wheat consumption exceeds 30 kg, totaling approximately 4 million tons nationwide. However, more than 95% of this demand is met through imports, resulting in a meager self-sufficiency rate of approximately 0.7%, raising concerns regarding supply stability and price fluctuations. Enhancing wheat self-sufficiency in Korea requires addressing yield reductions caused by abiotic stressors, including elevated temperatures, drought, cold damage and pre-harvest sprouting induced by climate change, as well as biotic stressors such as Fusarium head blight. The development of high-quality wheat varieties with superior processing characteristics that satisfy consumer demands is crucial. This study provides critical insights for future research on the development of novel wheat cultivars in Korea. It reviews the current state of wheat cultivation and production, environmental and biological factors affecting growth, compositional elements influencing quality, domestic cultivars developed through conventional crossbreeding currently in commercial distribution, and contemporary breeding trends, with particular emphasis on novel breeding technologies, such as biotechnology.

Climate change caused by global warming, is predicted to have severe consequences for ecosystems and economic sectors. In the agricultural industry, it is predicted that there will be decreased crop yields resulting from shifting planting seasons, as well as higher temperature and water stress which significantly reduce crop productivity. Kimchi cabbage, a cold-loving plant, is particularly vulnerable to high-temperature stress which can lead to stunted growth, increased susceptibility to pests like soft rot, reduced yield, and lower quality that will negatively impact the Kimchi cabbage market. Kimchi cabbage can be cultivated in highland regions with low summer temperatures and reduced pest occurrence, but rising temperatures and water stress are expected to increase pest pressure, resulting in a rapid decrease in the potential cultivation area of Kimchi cabbage. Currently, research is being conducted around the world to identify physiological mechanisms of heat tolerance at the molecular level, selection of heat-tolerant material, and studies on cellular responses of plants under high-temperature conditions. Despite numerous studies on physiological and biochemical responses of

However, this region experiences recurrent and severe drought risks driven by climate variability associated with the El Niño-Southern Oscillation (ENSO), resulting in significant economic losses. Consequently, biotechnology- based drought-tolerant soybean breeding has emerged as a critical national strategy across these countries. Argentina has positioned itself as a primary technology originator with the development of the HB4 soybean, the world’s first commercial drought-tolerant trait, utilizing the sunflower-derived transcription factor HaHB4. Brazil is advancing beyond single-trait approaches by developing multistacked biotech varieties that integrate drought tolerance with herbicide resistance, insect resistance, and oxidative stress mitigation. Furthermore, Paraguay and Uruguay are rapidly emerging as international hubs for field testing and commercialization, supported by streamlined regulatory frameworks and a “dual-track” strategy for both genetically modified (GM) and genome-edited (GE) crops. This review integrates molecular strategies, national regulatory systems, and commercialization trends in South America and discusses strategic implications for Korea. Despite Korea’s limited domestic experience in large-scale commercial cultivation owing to regulatory constraints, it possesses internationally competitive expertise in transcription factor engineering, CRISPR-based precision breeding, and AI-driven stress phenotyping. We propose a strategic technology export model that leverages Korea’s advanced R&D capabilities as a “technology provider” and “joint developer,” in partnership with South American countries. Such collaborations can foster a climate-resilient agricultural ecosystem and secure Korea’s position in the global biotech seed market.
‘Chamdongjin’ is a rice cultivar with a distinctively large grain size and good palatability, similar to ‘Sindongjin,’ which is a mega-cultivar in Korea. ‘Younghojinmi’ is a rice cultivar known for having the highest taste value among premium quality cultivars. In this study, we conducted quantitative trait loci (QTL) analysis of quality-related traits using recombinant inbred lines (RILs) derived from a cross between ‘Chamdongjin’ and ‘Younghojinmi’ to elucidate their genetic interactions. We analyzed 20 traits, including protein content, amylose content, glossiness of cooked rice, 7 traits related to grain appearance, 6 traits related to pasting properties, and 4 traits related to texture. Quality-related QTL were primarily detected on chromosome 3. In particular,

The development of pollen-free Lilium varieties can reduce the potential for allergies and increase the ornamental value as cut flowers. Moreover, lilies are not only ornamental but also edible, making them versatile in application. In this study, we developed a pollen-free Asiatic lily variety ‘Red Velvet’ with antioxidant activity. The crossbreeding was conducted in 2003 using the blackish-red ‘A3-22’ lineage and the orange and yellow bicolor ‘Cancun’. From the seeds produced, the pollen-free and color-excellent ‘A05-70’ was selected in 2005, and through growth and flowering characteristic tests, ‘Red Velvet (‘WonKyo C1-123’)’ was developed by 2015. Compared to the control ‘Brunello’, ‘Red Velvet’ exhibits superior horticultural characteristics, including taller plant height and excellent coloration in red and orange hues. Analyses of active components (total phenols and total flavonoids) and chemical antioxidant activity (DPPH and ABTS+ free radical scavenging) showed higher contents and antioxidant activity than the control, highlighting the potential for an expanded use of this new variety. The pollen-free ‘Red Velvet’ variety is expected to solve the problem of pollen issues and, through antioxidant activity research, expand the floriculture market and applications as a functional ingredient (Registration No. 6516).

Fusarium head blight (FHB) causes yield reduction, quality deterioration, and mycotoxin contamination in wheat, highlighting the need for resistant wheat varieties. In this study, we evaluated FHB resistance genes and infection rates in 44 domestic wheat varieties. Among them, 42 had the Type I resistance gene
In this study, we aimed to develop a method for the rapid and nondestructive prediction of wheat seed viability using Near-Infrared Spectroscopy (NIRS). Thirteen wheat cultivars were used to establish and validate an NIRS calibration model. The seed samples were divided into a calibration set (n=1,360) and a validation set (n=1,000), representing a wide range of germination rates created through the accelerated aging treatment (98±2% relative humidity, 40°C, 0-10 days). Spectral data were collected within the wavelength range of 400-2,500 nm. Among the three regression models tested, the Modified Partial Least Squares (MPLS) model exhibited the best performance for predicting seed viability, achieving the highest coefficient of determination (R2=0.936) and lowest standard error of calibration (SEC=7.514). The results of this study highlight the utility of NIRS-based models for the rapid, nondestructive assessment of seed viability in wheat. Additionally, this is the first study to apply NIRS for the nondestructive evaluation of wheat seed viability, providing a substantial advancement in seed quality assessment.
, Joo-Sung Im, Byung-Won Lee, YoungKwang Ju In 2022, Jindami was developed as an early maturing mealy sweet potato variety. It was derived from a cross between Dahomi (IT309420) with early maturity and Jinyulmi (IT327287) with early maturity and good palatability. The storage roots of Jindami have a light-purple skin, yellow flesh, and a reverse-ovate shape. When steamed, Jindami storage roots exhibit a mealy texture and are tenderer than those of the check variety, Jinyulmi. The sugar content of steamed Jindami storage roots was 25.4 mg/100 g on a dry weight basis, which was 6.0% higher than that of Jinyulmi. The marketable yield of Jindami storage roots was 28.6 t/ha in the early-season production, which was 19.2% higher than that of Jinyulmi with high yield in the early-season production. Jindami is resistant to root-knot nematode and

Image-based digitalization of germplasm stock holds significant promise for accelerating plant breeding and crop improvement. This technology facilitates efficient germplasm characterization, evaluation, and management through the capture and analysis of visual phenotypes. However, widespread adoption is hindered by challenges that include image quality control, data analysis complexity, and phenotypic representation limitations. This study investigated these constraints and proposed strategies to address them. By managing technical challenges, refining phenotypic data extraction, and developing robust data analysis pipelines, researchers can fully leverage image-based digitalization to enhance germplasm utilization and contribute to sustainable agriculture.

, Jong-Il Chung, Jin-Young Kim, Jin-Seong Moon, Jeong-Ho Shin, Hye-suk Yoon, Seon-Hui Kim, Mun-Hee Yang, Eon-Jung Ryu, Chan-Hee Kang, Jae-Won Cho, Jung-Sun Lee ‘Saebonghwang’ was developed as a mid-late ripening rice variety with good cultivation stability and yield in transplanting and under direct seeding cultivation. It was bred by backcrossing ‘Hopum’, which has excellent cultivation stability and adaptability to direct seeding, as a repeat parent, and ‘Hitomebore,’ a Japanese rice variety with excellent taste, as a donor. The heading date of ‘Saebonghwang’ was August 11 under ordinary planting, which is two days earlier than that of ‘Nampyeong’, and August 13 under wet-direct seeding cultivation, which is the same as that of ‘Dongan’. ‘Saebonghwang’ had a culm length of 74 cm under wet-direct seeding cultivation, which is larger than that of ‘Dongan’ (69 cm), and had good cultivation stability, including lodging resistance. ‘Saebonghwang’ is resistant to bacterial leaf blight and rice stripe virus and shows moderate resistance to rice blast. Furthermore, ‘Saebonghwang’ has better grain appearance, superior taste and better milling characteristics than ‘Nampyeong’. The yield of ‘Saebonghwang’ when cultivated under ordinary planting, wet-direct seeding, and double cropping was 5.65, 5.37, and 5.37 MT/ha, respectively. Under wet direct sowing by drone cultivation, ‘Saebonghwang’ showed good initial survival rate and cultivation stability. The yield was 4.49 MT/ha, slightly lower than that obtained under transplanted cultivation (5.03 MT/ha), but was not statistically different; therefore, ‘Saebonghwang’ was adjudged to be adaptable to drone wet-direct seeding. ‘Saebonghwang’ can be used in various ways to suit the working conditions of farms, increase farm work efficiency, and expand the area of wet direct-seeding cultivation (Registration No. 9171).

Most paprika farmers in Korea have grown bell-type paprika, mostly for export to Japan. However, continued long-term yen depreciation has worsened the export profitability of paprika, increasing domestic sales and decreasing farmers’ income. Gyeongsangnam-do Agricultural Research and Extension Services developed ‘New Daon Red’ as a new mini paprika to replace some bell-type paprika cultivation to cope with the change. The maternal line, Trirosso, has deep orange conical fruits with good fruit set, while the paternal line, SBR970, exhibits red fruits and stable fruiting with strong vegetative growth. F1 ‘New Daon Red’ was selected as an excellent cultivar for fresh consumption in 2018 from the on-site test that lasted 2 years starting in 2017. This cultivar showed similar plant height to the control ‘Raon Red’ but had larger leaves. The fruit weighed 71 g, 8% heavier than that of the control, with a longer and narrower shape. Fruits of ‘New Daon red’ had a sweetness level of 9 °Brix and were soft. The occurrence rates of blossom-end rot and skin cracking were 1.4% and 2.4%, respectively, in ‘New Daon Red,’ while they were 0.2% and 0.8% in ‘Raon Red.’ However, ‘New Daon Red’ had a 26% higher yield per land unit due to its better fruit set than the control cultivar. Therefore, it is expected that the high productivity of this cultivar, along with good fruit quality, could contribute to increasing farmers’ income (Registration No. 9684).
