Abstract

A new soybean cultivar 'Daewang' was released by Agricultural Research & Extension Services, Gangwon Province in 2008. The Goals of breeding the variety was for large seed size, high yield, lodging tolerance and resistance to diseases such as soybean mosaic virus (SMV) and bacterial pustule. 'Daewang' was derived from the cross of GWS91, which has yellow seed coat, large seed size and late maturity, and 'Seokryang-putkong', which has large seed size and early maturity. The preliminary, advanced and regional yield trials for evaluation and selection were carried out from 2002 to 2007. It has a determinate growth habit with purple flower, yellow seed coat, yellow hilum and large seed weight (33.6 g per 100 seeds). The maturity date of 'Daewang' is 16 days later than the 'Taekwang'. It has a high content of total isoflavone ($1,851{\mu}g/g$). The average yield of 'Daewang' was 2.68 MT/ha in the regional yield trials (RYT) carried out in four locations in Gangwon province from 2004 to 2007 which was 4 percent higher than the check cultivar 'Taekwang'.

'대왕'은 대립이며 종자 특성이 우수한 GWS91을 모본으로 하고 '석량풋콩'을 부본으로 1996년도에 인공교배를 하고 1997년부터 1998년까지 $F_1-F_2$ 양성하였다. 1999년부터 2001년도에 $F_3-F_5$ 세대를 계통육종법으로 선발한 GSL96202-2B-1-3-7계통으로 계통명은 '강원106호'이다. 주요 특성은 다음과 같다. 1. 유한신육형이며 꽃색은 자색이고 엽형은 난형이다. 입형은 구형이고 종피색은 황색, 제색은 황색이며 100립중은 33.6g으로 대립이다. 2. 개화기는 7월 27일, 성숙기는 10월 20일로 '태광콩'에 비하여 만생종이다. 3. 종실 성분중 조단백질 함량은 38.3%로 조단백질 함량에서 '태광콩'보다 다소 많았으며, 조지방 함량은 17.1%로 다소 낮았다. 기능성 성분중 아이소플라본 함량이 $1,851{\mu}g/g$로 다소 높았다. 4. 수량성은 2004년부터 2007년까지 4개년간 실시한 지역 적응시험결과 강원도 4개소 평균수량은 2.68 MT/ha로 '태광콩' 2.56 MT/ha보다 약 4% 증수하였다.
