Perilla is a traditional oilseed crop cultivated in Korea. The ‘Nulsaemi’ cultivar was developed for oil use because of its large seed size and high functional compound content. It originated from a cross between ‘Daesil’ (IT274265), with high crude fat content and a soft seed coat, and ‘Milyang16’ (K015415), with large, brown seeds and a hard seed coat. The cross was created in 2008, and promising lines were selected through pedigree breeding up to the F₆ generation. Advanced yield trials were conducted in 2016 and regional yield trials were conducted at four sites (Milyang, Suwon, Cheongju, and Iksan) from 2017 to 2019. ‘Nulsaemi’ matures around October 8, which is slightly later than the standard cultivar ‘Dayu’. It also has a 1,000-seed weight of 5.2 g, which is 1.4 g heavier than ‘Dayu’. The seed hardness was low, making it suitable for processing. The average yield was 125 kg/10a, about 3% higher than that of ‘Dayu’. The seeds contained approximately 45.1% crude fat and 63.4% alpha-linolenic acid, similar to those of the standard cultivar. However, rosmarinic acid content was significantly higher at 2,130.6 μg/g, about 18% more than ‘Dayu’. In sensory evaluation, oil extracted from ‘Nulsaemi’ showed better appearance, aroma, taste, and overall preference compared to the control, in both cold-pressed and roasted oil types. ‘Nulsaemi’ is expected to be a high-quality oilseed cultivar suitable for premium perilla oil production (Registration No. 8792).

‘Saebom’ is a new vegetable perilla (Perilla frutescens (L.) Britton) variety developed at the National Institute of Crop Science, Rural Development Administration, in 2020, following a cross made in 2011 between YPL54-2B-36-1-1-1-2-2 and YPL83-2B-5-2-5. It was developed using a pedigree breeding method. YPL156-2B-9-2-1-3-2 was selected and named ‘Milyang 83.’ Subsequently, summer and winter productivity tests were conducted. ‘Saebom’ has small, round-shaped leaves and its maximum leaf length is 13.1 cm, which allows for the distribution of leaf harvesting labor. In addition, the leaves are thick, which is beneficial for storage, and the ratio of the apical leaf length/leaf length is 55.8% (‘Namcheon’ 37.2%). This value is considered high and makes ‘Saebom’ highly marketable. Its leaf yield and leaf number were 10% and 8% higher than those of ‘Namcheon,’ respectively, and its antioxidant activity was also higher. In December 2020, the variety was named ‘Saebom’ by the new variety selection committee for its excellence, and its variety protection rights were registered in 2023 (Registration No. 9305).

‘Saedeul’ is a saddle-patterned seed-coated soybean cultivar developed from a cross between ‘IT224183’ and ‘Daepung (IT214696)’ in 2010. The F1 and F2 generations were grown for 2 years, and promising lines were selected using the pedigree method from F3 to F5 generations. The preliminary yield trials (PYT) and advanced yield trials (AYT) were conducted during 2016-2017, followed by regional yield trials (RYT) across seven regions during 2018-2020. ‘Saedeul’ is a determinate cultivar, having oval-shaped leaflets, purple flowers, and saddle-patterned seeds. The flowering and maturing date were August 11 and October 28, respectively. Considering its quantitative characteristics in comparison to the ‘Cheongja3ho’ cultivar, ‘Saedeul’ has a smaller seed size (27.9 g/100 seeds) and shorter plant height, but a higher first pod height. ‘Saedeul’ showed greater tolerance to both lodging and pod shattering in the RYT field and indoor tests than ‘Cheongja3ho’. It demonstrated resistance to bacterial pustule in field tests but was susceptible to soybean mosaic virus (G6H strain) in inoculation tests. The mean yield of ‘Saedeul’ in the RYT was 261 kg/10a, exceeding that of ‘Cheongja3ho’. ‘Saedeul’ is expected to replace landraces due to its resistance to lodging and bacterial pustule.
