‘호반’은 대립이며 종자 특성이 우수한 GWS91을 모본으로 하고 Lipoxygenase 2와 3이 결핍된 ‘진품콩’을 부본으로1995년도에 인공교배를 하고 1996년부터 1997년까지 F1-F2양성하였다. 1998년부터 2003년도에 F3 이후 세대를 전개하며 계통육종법으로 선발한 GSL95102-2B-16-5-1-1계통으로계통명은 ‘강원5호’이다. ‘호반’의 주요특성으로는 유한신육형이며 꽃색은 자색이고 엽형은 난형이다. 입형은 편구형이고종피색은 황색, 제색은 황색이며 100립중은 29.0 g으로 대립이다. 개화기는 7월 23일, 성숙기는 10월 5일로 ‘진품콩 2호’와 유사한 중만생종이다. 종실 성분중 조단백함량은 39.0%로‘진품콩 2호’와 유사하였고, 조지방 함량은 18.5%로 다소 높았다. 기능성 성분중 아이소플라본 함량이 1,995 ㎍/g 로‘진품콩 2호’보다 25% 높았으며, 콩 비린내 유발 효소인 Lipoxygenase 2가 결핍되었다. 조단백 함량은 ‘진품콩 2호’와 유사하였으나, 조지방 함량은 다소 높았고, 메주와 청국장가공 시 발효정도와 풍미가 ‘진품콩 2호’보다 양호하였으며,청국장 수율도 높았다. 수량성은 2004년부터 2006년까지 3년간 실시한 지역적응시험결과 단작지에서 2.69 MT/ha로‘진품콩 2호’ 2.62 MT/ha 대비 3% 증수하였고, 이모작지에서는 2.60 MT/ha로 ‘진품콩 2호’ 2.59 MT/ha와 차이가 없었다.
A new soybean cultivar ‘Hoban’ was released by ARES, Gangwon Province in 2007. The Goals of breeding were for large seed size, high yield, lodging tolerance, and resistance to diseases such as soybean mosaic virus (SMV) and bacterial pustule. ‘Hoban’ was derived from the cross of GWS 91, which has yellow seed coat, large seed size and late maturity, and ‘Jinpum’, which lacked two of three lipoxygenase isoenzymes (L-2 and L-3). The preliminary, advanced and regional yield trials for evaluation and selection were carried out from 2001 to 2006. ‘Hoban’ was characterized as lipoxygenase 2 free, large seed. It has a determinate growth habit with purple flower, yellow seed coat, yellow hilum and large seed weight(29.0g per 100 seeds). The maturing date of ‘Hoban’ was Oct. 5. The content of total isoflavone was 1,995㎍/g which was 25% higher than check variety (‘Jinpumkong 2’). The average yield of ‘Hoban’ was 2.69 MT/ha in the regional yield trials (RYT) carried out in two locations of Korea from 2004 to 2006 which was 3 percent higher than the check variety ‘Jinpumkong 2’. SDS-PAGE on grain storage protein shows that ‘Hoban’ was diffcient in lipoxygenase 2.
