A new Adzuki bean cultivar, ‘Hongmiin’, was developed from the cross between K204656 (Toyomidainagon) and SA9905 in 2008. Hongmiin showed prominent agronomical characteristics, such as high grain quality, lodging resistance, and high yield in the regional adaptation yield trials (RYT) conducted for four years from 2017 to 2020. ‘Hongmiin’ is an early maturing variety, having a bright red seed coat, and the sediment ratio of this red bean was high because of the thin seed coat. The mean plant height of ‘Hongmiin’ was 58 cm, and its yield components were 7.4 pods per plant and a 100-seed-weight of 20.5 g of in the regional yield trials (RYT). This indicates that the Hongmiin has appropriate trait values for red bean production and processing. In the regional yield trial for the four years, the average yield potential of ‘Hongmine’ was 2.09 MT/ha, which is 8% higher than that of ‘Arari’ (Registration No. 9324).

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).

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).
