An Adzuki Bean (Vigna Angularis) Cultivar ‘Honggyeong’ with Bright Red Seed-Cort Color and Resistance to Lodging Stress

Abstract

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).
