초록
‘Seum’ is a black-seed coated soybean cultivar developed from crossing ‘IT21785’and ‘Wonkwang (IT218557)’ in 2010. F1 and F2 populations were grown for 2 years andpromising lines were selected by pedigree method from F3 to F5. The preliminary yield trial(PYT) and advanced yield trial (AYT) were conducted from 2016 to 2017, and regional yieldtrial (RYT) in 7 regions was conducted from 2018 to 2020. ‘Seum’ is determinate, has a lanceolateleaflet shape, purple flowers, green cotyledons, and black spherical seeds. Flowering and maturing dates were Aug. 4 and Oct. 21, respectively. ‘Seum’ has smallseed size (11.4 g/100-seed) and shorter plant height than that of ‘Socheongja’. ‘Seum’was more tolerant to lodging and pod shattering in regional field and indoor trials than thatof ‘Socheongja’. ‘Seum’ was resistant to bacterial pustule during field tests and to soybeanmosaic virus (G6H strain) during inoculation tests. The mean yield of ‘Seum’ in RYT was292 kg/10a which was higher than that of ‘Socheongja’. ‘Seum’ is expected to rapidly replacethe elite variety ‘Socheongja’ based on its lodging tolerance and high yield potential(Registration No. 9449).
