Abstract

This study was carried out to examine growth characteristics and seed qualities of 1,296 Korean soybean landraces. The range of days to flowering, and days to maturity was 38 to 83 days and 47 to 102 days, respectively. The range of growth days were 105 to 160 days, and 38% was belonged to maturity group III. The 100 seed weight was 19.5g, showing the range of 2.4 g to 40.4 g, and 19.5 g in mean. 35.3% was in the range from 13.1 g to 20.0 g, and 29.4% in the range from 20.1 g to 25.0 g. Mean contents of crude protein was 41.8%, showing the range from 32.7% to 49.2%. Mean contents of crude oil was 18.0%, showing the range from 11.8% to 22.2%. The composition of unsaturated fatty acids were from 81.8% to 94.2%, and 85.4% in mean. Sucrose contents were in the range from 1.24% to 7.91% with the mean 5.21%, and oligo-saccharide contents from 2.45% to 11.13% with the mean 8.01%. Total isoflavone contents were in the range from $278.4\;{\mu}g/g$ to $2,736.9\;{\mu}g/g$ with the mean $1,066.8\;{\mu}g/g$. Among isoflavone contents, daidzein, glycitein, and genistein contents were in the range from $48.8\;{\mu}g/g$ to $1,709.6\;{\mu}g/g$ with the mean $483.2\;{\mu}g/g$, from $0.98\;{\mu}g/g$ to $892.3\;{\mu}g/g$ with the mean $111.6\;{\mu}g/g$, and from $79.8\;{\mu}g/g$ to $1242.3\;{\mu}g/g$ with the mean $472.0\;{\mu}g/g$, respectively.
