Paddy Field and Mechanization-Adaptable Soybean Cultivar, ‘Jangpung’, with Fewer Branches and Higher First Pod Height

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).
