A new small red bean cultivar, 'Seona', was artificially crossed between 'SA9201-2B-18-1-4-1-4' and SA9411-2B-1-1-2 in 1999, with fixed excellent agronomic characters using the pedigree breeding method, and selected for the further trials a 'Miryang 18'. It was prominent and had desirable characteristics such as high grain quality, lodging resistance, and high antioxidant activity in the regional adaptation yield trials (RYT) for three years from 2012 to 2014 and was released for public consumption as 'SA9914-2B-9-2-3-3-1' in 2014. 'Seona' has a semi-determinate growth habit, yellow flowers, green embryonic axis, dark red seed coat, white hilum, and small spherical seeds (15.6 g per 100 seeds). The average yield of 'Seona' was 2.04 MT/ha in the regional yield trials (RYT) carried out for three years from 2012 to 2014, which was a slightly higher than that (1.97 MT/ha) of the control variety, 'Chungju' (Registration No. 6051).

A new small redbean cultivar, 'Hongjin', was developed by an artificial cross between 'SA9206-2B-6-1-2-3-3-2' and 'Suwon38' at the National Institute of Crop Science, RDA, Korea, in 1999, and selected for the further yield trials under the name 'Miryang 23'. It was prominent and had desirable agronomic traits, such as high grain quality, lodging tolerance, and high antioxidant activity in the regional adaptation yield trials (RYT) from 2013 to 2015. 'Hongjin' was finally released as a new cultivar in 2015. 'Hongjin' has some distinct phenotypic traits, including a semi-determinate growth habit, yellow flowers, green embryonic axis, dark red seed coat, white hilum, and small spherical seeds (15.4 g per 100 seeds). The average yield of 'Hongjin' was 1.99 MT/ha in the regional yield trials (RYT), which was slightly higher than that of the check cultivar 'Chungju' (1.84 MT/ha) (Registration No. 7510).

In 2008, a new adzuki bean (Vigna angularis) cultivar, 'Honggyeong', was developed using artificial cross between 'Milyang 7 (SA9709-2B-8-2-4-4-1)' and 'SA0001' at the National Institute of Crop Science, RDA, Korea. It was selected for further yield trials-named 'Miryang 36'. This cultivar was prominent and showed desirable agronomic traits, such as lodging tolerance, high yield, and high antioxidant activity during the regional adaptation yield trials (RYT) from 2016-2018. 'Honggyeong' was finally released as a new cultivar in 2018 and its distinct phenotypic traits included a semi-determinate growth habit, yellow flowers, green embryonic axis, bright red seed-cort color, white hilum, and large seeds (18.4 g per 100 seeds). The average yield of 'Honggyeong' was 2.06 MT/ha in the regional yield trials (RYT), which was slightly higher than that of the check cultivar (1.89 MT/ha), 'Chungju' (Registration No. 7934).

With the aim of developing an adzukibean variety to manufacture white bean pasta, an adzukibean (Vigna angularis) cultivar, "Huinnarae" was developed in 2014. "Huinnarae" was developed in 2003 by crossing Gyeongwon and Sodubanggei 3. It was a late-maturing variety, having a bright yellow seed coat. Moreover, "Huinnarae" showed more white lightness than "Chungju." Its plant height was 79 cm, and its yield components showed 6.7 pods per plant and 16.6 g of 100-seed weight in the regional yield trial(RYT). Further, in the RYT conducted for the three years, the average yield potential of "Huinnarae" was 1.86 MT/ha, which was 4% lower than that of "Chungju." Moreover, it is suitable to make white bean pasta. "Huinnarae" is expected to increase diversity, create new demand surges, and improve the value and consumption of adzukibean (Registration 6050).

A new small red bean cultivar, 'Geomguseul', was artificially crossed between 'Chilbo' and 'SA8412-3-1-4-3-3-2-3' in 1998, fixed excellent agronomic characters by pedigree breeding method, and selected for the further trials with the name of 'Miryang 10'. It was prominent and showed good result, such as high grain quality, lodging resistance, and high-antioxidant activity in the regional adaptation yield trials (RYT) for three years from 2009 to 2011 and released for the public consumption as the name of 'SA9801-24-4-3-1' in 2011. 'Geomguseul' has a semi-determinate growth habit, yellow flower, green embryonic axis, black seed coat, white hilum, and small spherical seed (12.2 grams per 100 seeds). The average yield of 'Geomguseul' was 2.01 MT/ha in the regional yield trials (RYT) carried out for three years from 2009 to 2011 which was a little higher than that (1.98 MT/ha) of the check variety, 'Chungju'.
