A new soybean cultivar ‘Hoban’ was released by ARES, Gangwon Province in 2007. The Goals of breeding werefor large seed size, high yield, lodging tolerance, and resistance to diseases such as soybean mosaic virus (SMV) and bacterialpustule. ‘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 trialsfor 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 checkvariety (‘Jinpumkong 2’). The average yield of ‘Hoban’ was 2.69 MT/ha in the regional yield trials (RYT) carried out in twolocations of Korea from 2004 to 2006 which was 3 percent higher than the check variety ‘Jinpumkong 2’. SDS-PAGE on grainstorage protein shows that ‘Hoban’ was diffcient in lipoxygenase 2.
