A small red bean cultivar, ‘Haeorom’, was developed by artificial cross breeding between ‘Milyang 7 (SA9709-2B-8-2-4-4-1)’ and ‘Toyomidainagon (K204656)’ at the National Institute of Crop Science, RDA, Korea in 2008, and selected for further yield trials under the name ‘Miryang 27’. It was prevalent and showed desirable agronomic traits such as lodging tolerance, high yields, and strong antioxidant activity during the regional yield trials (RYT) from 2014 to 2016. ‘Haeorom’ was released as a new cultivar in 2016. It has some distinct phenotypic traits, including a semi-determinate growth habit, yellow flower, green embryonic axis, bright red seed, white hilum, and small spherical seeds (18.6 g per 100 seeds). The average yield of ‘Haeorom’ was 2.04 MT/ha in the RYT, which was slightly higher than that of the check cultivar (1.87 MT/ha), ‘Chungju’ (Registration No. 7508).

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).
