Abstract
The soybean cultivar ‘Gangpoong’ was developed for soy-paste and tofu. Suwon 223 and SS 00419 were crossed in 1999 and their progenies were selected from F3 to F5 using the pedigree method. Preliminary yield (PYT) and advanced yield (AYT) trials were conducted from 2008 to 2010, and regional yield trials (RYT) were conducted at three locations from 2011 to 2013. In RYT, ‘Gangpoong’ was stable in variable environments. ‘Gangpoong’ was determinate, with white flowers, yellow elongated spherical seeds, and a light brown hilum. The flowering and maturity dates were July 27 and October 8, respectively. The plant height was 67 cm shorter than that of ‘Daewonkong’ (81cm, standard cultivar). ‘Gangpoong’ had fewer node numbers (16) than that of ‘Daewonkong (18) and had a heaver seed weight (30.1 g/100-seed weight) than that of ‘Daewonkong (26.0 g/100-seed weight)’. ‘Gangpoong’ showed lodging tolerance. The tofu yield of ‘Gangpoong’ was 213%, and the physical characteristics of tofu were similar to those of ‘Daewonkong (208%, standard cultivar)’. The soybean malt scent and fermented soybean yield of ‘Gangpoong’ were 2 and 105%, respectively. The yield in adaptable regions was 3.4 MT/ha, which was 14% higher than that of ‘Daewonkong’. Therefore, ‘Gangpoong’ could be cultivated and used widely for soy-paste and tofu in the near future (Registration number: 5932).
