Soybean cultivar ‘Seonpung’ was developed for soy-paste and tofu. Suwon 224 and YS1325-3S-2 were crossed in 2003 and selected from F3 to F5 by pedigree method. The preliminary yield trial (PYT) and advanced yield trial (AYT) were conducted from 2009 to 2010, and regional yield trial (RYT) in twelve regions was conducted from 2011 to 2013. In RYT, ‘Seonpung’ was stable in variable environments and a high yield cultivar. ‘Seonpung’ is determinate, white flower, yellow spherical seed and yellow hilum. Flowering date and maturity date were Aug. 5 and Oct. 19, respectively. Plant height was similar to ‘Daewonkong (standard cultivar)’. However ‘Seonpung’ has higher node number (16) and seed weight (25.9g/100-seed weight) than ‘Daewonkong’ (14 and 24.2g/100-seed weight). ‘Seonpung’ is resistant to root rot, and it also has high level of resistance to bacterial pustule and soybean mosaic virus. The yield of tofu of ‘Seonpung’ was 241%, and noticeably lighter, and solidity was higher than ‘Daewonkong’. Soybean malt scent, fermented soybean yield and γ-polyglutamic acid (γ-PGA) of ‘Seonpung’ were 4, 181% and 31.7㎎/g. The yield in adaptable regions was 340kg/10a (21% increase compared to ‘Daewonkong’). ‘Seonpung’ is expected to be cultivated and used widely for soy-paste and tofu. (Registration number: 5931)
‘청아’는 내재해 다수성 장류용콩 신품종을 육성하기 위하 여 내도복, 다수성 품종인 ‘신팔당콩 2호’를 모본으로 1999년 도에 인공교배한 SS99505 조합으로 계통육성법으로 선발하였으며 계통명은 ‘강원 110호’이다. 꽃색은 백색이고 잎모양 은 난형이며, 종자모양은 구형이다. 종피색과 배꼽색은 황색 이고 백립중은 25.2 g으로 ‘태광’보다 2.4 g 무거운 대립이다. ‘태광’에 비하여 개화기는 7월 20일로 11일 빠르고 성숙기는 9월 30일로 5일 빨라 조숙종이면서도 등숙기간은 6일 길다. 특히, 도복에 강하며 불마름병과 바이러스에 강하다. 수량성 은 ‘태광’보다 생산력검정시험에서는 15% 증수하였고, 철원 등 4개 단작지역 적응성검정시험에서는 14% 증수하여 평균 종실수량이 ha당 2.72톤이다.
A new soybean cultivar for tofu and soy-paste, "Daemang 2", was developed from the cross between 'Shinpaldal 2' and'Seokryang' by soybean breeding team in the Yeongnam Agricultural Research Institute (YARI) in 2005. A promising line,SS93205-2B-8-3-2-1-1-1
