‘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).

The soybean cultivar, ‘Jangpung’, is adaptable for mechanized harvest with fewer branches and a higher first pod height. ‘Jangpung’ was developed through a pedigree method involving a cross between ‘Shingi’ and ‘SS03102-B-B-3S-21-4’ cultivars from 2010-2021. The promising line, ‘YS2243-B-B-35-1-1-1’, was selected and designated as ‘Milyang361’, whereafter it was tested in regional yield trials (RYT) for three years from 2019-2021. Its performance and stability were approved after the RYT and thereafter released as ‘Jangpung’. It has a determinate growth habit, purple flowers, grey pubescence, yellow seed coat, yellow hilum, spherical seed shape, and large seeds (28.2 g/100 seeds). ‘Jangpung’ is a late-maturing cultivar; its flowering and maturing dates were 9 August and 22 October, respectively. ‘Jangpung’ exhibited resistance to bacterial pustule and soybean mosaic virus, as well as tolerance to lodging and shattering resistance, as confirmed through genetic validation using the marker, qPDH-KS. Considering its higher first pod height, lodging and shattering tolerance, and disease resistance, the soybean cultivar, ‘Jangpung’, might assist soybean producers in achieving high adaptability for mechanization and paddy field cultivation (Registration number: 9972).

A soybean cultivar, “Seonyu2ho” for double cropping using soy-paste and tofu was developed in 2011 using the pedigree method by crossing “Milyang235ho” and “Jungmo3004ho.” A promising line, YS2441-B-2S-11-3, was selected and named as “Milyang334.” It demonstrated prominent early maturing, shattering resistance, and high yield in regional yield trials (RYTs) from 2017 to 2019, and was released by the name “Seonyu2ho.” The cultivar showed a determinate growth habit, white flowers, grey pubescence, yellow seed coat, yellow hilum, flat-spherical seed shape, and large seed size (27.9 g per 100 seeds). “Seonyu2ho” matured on October 5 (112-growing day cycle) in RYT and was suitable for double cropping with winter crops, such as wheat, barley, and onion. It was resistant to bacterial pustule and soybean mosaic virus and tolerant to lodging in fields. Particularly, “Seonyu2ho” showed a high yield (3.34 ton/ha) and shattering resistance, even if the previously developed early matured cultivars exhibited low yield and easy shattering. Overall, “Seonyu2ho” can contribute to stable soybean production in double cropping.

A white sesame variety ‘Nuri (Sesamum indicum L.)’ with resistance to Phytophthora blight disease was developed in 2016. It was derived from a cross between ‘Suwon 131’ and ‘Yangbaek’ in 1999. ‘Nuri’ has few branches and triple capsules per node. Notably, ‘Nuri’ exhibited resistance to Phytophthora blight and Fusarium wilt and a yield of approximately 1.19 tons per hectare, 17% higher than that of ‘Kopoom’. ‘Nuri’ presented a crude fat content of 49.0% and protein content of 26.1%. Thus, this variety would contribute to increased sesame production. (Registration no. 7889).

‘Cheongmiin’ is a green seed-coated soybean cultivar developed from a cross between ‘Cheongjakong’ and ‘Daemang’ in 2002. The F₁ and F₂ populations were grown for 2 years, and promising lines were selected based on the pedigree method from generations F₃ to F₅. Preliminary and advanced yield trials were conducted from 2009 to 2010, and regional yield trials (RYTs) were conducted in eight regions from 2011 to 2013. ‘Cheongmiin’ is a determinate soybean with white flowers, green cotyledons, and spherical green seeds. The average flowering and maturing dates of ‘Cheongmiin’ were August 1^st and October 22^nd, respectively. In terms of quantitative characteristics, ‘Cheongmiin’ has a larger seed size (34.3 g/100-seed weight) than that of ‘Cheongdu1ho’ (24.5 g/100-seed weight), and has also been shown to be tolerant to lodging and pod shattering in the field in RYTs and oven drying tests, respectively. Furthermore, ‘Cheongmiin’ has been found to be resistant to bacterial pustules in the field and soybean mosaic viruses (G5H and G6H strains) in inoculation tests. The mean yield of ‘Cheongmiin’ in the RYTs was 272 kg/10 a, which was 4% higher than that of ‘Cheongdu1ho’. Given its large seed size and seed coat color, ‘Cheongmiin’ is expected to be highly useful for cooking with rice and for the preparation of rice cakes (Registration No. 7688).

‘Haewon’ is a soybean cultivar for soy-sprouts. ‘Bosug’ and ‘Somyeong’ were crossed in 2003, and promising lines were selected from F3 to F6 using the pedigree method (Pedigree: HS1450-2B-3-1-1-2-2-1). Preliminary yield (PYT) and advanced yield trials (AYT) were conducted from 2010 to 2011, and regional yield trials (RYT) were conducted in five regions (Suwon, Naju, Miryang, Dalseong, and Jeju) from 2012 to 2014. In the RYTs, ‘Haewon’ had a smaller seed weight and higher yield than the standard cultivar ‘Pungsannamulkong’, which are desirable characteristics for the soy-sprout process. The morphological characteristics of ‘Haewon’ are as follows: determinate plant type, purple flowers, gray pubescence, yellow pods, small, yellow spherical seeds (8.1 g/100-seeds), and light brown hilum. The flowering and maturity dates were July 29th and October 6th, respectively. Plant height and first pod height were 55 cm and 12 cm, respectively. The lodging tolerance was also strong compared to that of ‘Pungsannamulkong’. The germination rate, total length, hypocotyl length, thickness, and sprout yield of soybean sprouts were 97%, 19.1 cm, 8.8 cm, 2.1 mm, and 513%, respectively. The yield in adaptable regions was 337 kg/10 a, 16% higher than that of ‘Pungsannamulkong’. ‘Haewon’ can be used for soy-sprout with favorable seed size and soy-sprout characteristics, such as germination and sprout-yield.

Perilla has a long history of cultivation and consumption in Korea. Its cultivar ‘Sodam’, which is used for its oil and powder, was developed from a cross between two parents ‘K015926’ and ‘Miryang27’. The parents were crossed in 2004, and their progenies were selected from F₃ to F₅ generations through pedigree method. Regional yield trials (RYTs) were conducted in four regions from 2012 to 2014. ‘Sodam’ is a light gray and small spherical-seeded cultivar. It matures earlier (October 2) than ‘Saeyeopsildeulkkae’, a standard cultivar, and the number of flower clusters per plant as well as the number of ears per cluster is higher in ‘Sodam’ than in the standard cultivar. Its seeds contain approximately 46.4% crude fat, and the oil is rich (about 65.0%) in alpha-linolenic acid, an omega-3 fatty acid. ‘Sodam’ is characterized by upright plant growth with narrow branch angles. The average yield of this cultivar was 1.23 ton/ha in adaptable regions. ‘Sodam’ is expected to be a potential cultivar source for production of good quality perilla oil (Registration No. 6729).

‘Aram’ is a soybean cultivar developed for soy-sprout. It was developed from the crossing of ‘Bosug’ (Glycine max IT213209) and ‘Camp’ (G. max IT267356) cultivars in 2007. F₁ plants and F₂ population were developed in 2009 and 2010. A promising line was selected in the F₅ generation in 2011 using the pedigree method and it was evaluated for agronomic traits, yield, and soy-sprouts characteristics in a preliminary yield trial (PYT) in 2012 and an advanced yield trial (AYT) in 2013. Agronomic traits and yield were stable between 2014 and 2016 in the regional yield trial (RYT) in four regions (Suwon, Naju, Dalseong, and Jeju). Morphological characteristics of ‘Aram’ are as follows: determinate plant type, purple flowers, grey pubescence, yellow pods, and small, yellow, and spherical seeds (9.9 g 100-seeds^-1) with a light brown hilum. The flowering date was the 5^th of August and the maturity date was the 15^th of October. Plant height, first pod height, number of nods, number of branches, and number of pods were 65 cm, 13 cm, 16, 4.5, and 99, respectively. In the sprout test, germination rate and sprout characteristics of ‘Aram’ were comparable to that of the ‘Pungsannamulkong’ cultivar. The yield of ‘Aram’ was 3.59 ton ha^-1 and it was 12% higher than that of ‘Pungsannamulkong’ in southern area of Korea. The yield of ‘Aram’ in the Jeju region, which is the main region for soybean sprout production, was 20% higher than that of ‘Pungsannamulkong’. The height of the first pod and the tolerance to lodging and pod shattering, which are connected to the adaptation to mechanized harvesting, were higher in ‘Aram’ compared to those in ‘Pungsannamulkong’. Therefore, the ‘Aram’ cultivar is expected to be broadly cultivated because of its higher soybean sprout quality, and seed yield and better adaptation to mechanized harvesting.

Haepum’ is a soybean cultivar for soy sprouts. ‘Bosug’ and ‘Suwon 214’ were crossed in 2001, and promised lines were selected from F₃ to F₅ using the pedigree method (Pedigree: HS1273-2B-4-1-2-3-3). Preliminary yield (PYT) and advanced yield (AYT) trials were conducted from 2008 to 2009, and regional yield trials (RYT) in four regions (Suwon, Naju, Miryang, Jeju) were conducted from 2010 to 2012. In RYT, ‘Haepum’ had higher plant height and first pod height than other cultivars, which are desirable characteristics for mechanized harvest. Morphological characteristics of ‘Haepum’ are as follows: determinate, white flowers, grey pubescence, yellow pods, yellow spherical small seeds (10.4 g/100 seeds), and light brown hilum. The flowering and maturity dates were July 29 and October 6, respectively. Plant height was 61 cm, 6 cm longer than that of ‘Pungsannamulkong’ (standard cultivar). Moreover, the first pod height of ‘Haepum’ was 15 cm, 6 cm longer than that of ‘Pungsannamulkong’. The lodging tolerance was also stronger (1) than that of ‘Pungsannamulkong’ (6). The germination rate, total length, hypocotyl length, thickness, and sprout yield of ‘Haepum’ soybean sprouts were 99%, 20.6 cm, 9.7 cm, 2.1 mm, and 453%, respectively. The yield in adaptable regions was 301 kg/10 a, which was 10% higher than that of ‘Pungsannamulkong’. ‘Haepum’ could be broadly used for soybean sprout culture and an adequate cultivar for conversion to jeju and mechanized harvesting.

Perilla cultivar ‘Deulsaem’ was developed for perilla oil and powder. ‘YPL139’ and ‘Daesildeulkkae’ crossed in 2003 and selected from F₃ to F₅ by pedigree method. The selected pedigree is ‘YPS142-B-28-1-3-2-2’ and named as Miryang No. 57. The regional yield trial (RYT) in five regions was conducted from 2011 to 2013. In RYT, ‘Deulsaem’ was a high yield and quality. ‘Deulsaem’ is determinate, white flower and brown spherical seed. Maturity date was Oct. 8, similar to ‘Saeyeopsildeulkkae’(standard cultivar). However, ‘Deulsaem’ has higher number of flower cluster and ear per cluster than ‘Saeyeopsildeulkkae’. The yield of oil content and linolenic acid of ‘Deulsaem’ was 39.4% and 61.0%, respectively. The yield in adaptable regions was 1.42 ton/ha (5% increase compared to ‘Saeyeopsildeulkkae’) and ‘Deulsaem’ is expected to be cultivated and used widely for good quality perilla oil.

An interspecific cross between P. citriodora and P. hirtella constitutes ideal material for a linkage map construction in genome project of Perilla. The chromosomes of the species are same with n=10 and progenies of the cross are normal in growth and seed set. The phenotype of F2 population of the cross are normally distributed and this is a proof of high affinity of the chromosomes during their sexual reproduction. Rosmarinic acid, Luteolin and Apigenin contents of F2 plants were distributed in similar range with tetraploid perilla cultivars. Luteolin and Apigenin are positively correlated with correlation coefficient of 0.762. 21 QTLs were detected in agronomic traits and Rosmarinic acid, Luteolin and Apigenin contents. Even though Luteolin and Apigenin are positively correlated, QTLs were located in different position. Purple leaf color related QTL was mapped in Chromosome 3 with LOD of 14.3, PVE of 50.4%. Three anthocyanin biosynthesis transcription factor like sequences, WD40 repeat-like superfamily protein, myb domain protein 43 and basic helix-loop-helix (bHLH) DNA-binding superfamily protein, were detected near from the QTL.
