Agronomic Characteristic and Nutrient Content from Several Soybean Promising Lines with High Isoflavones

Soybean is a high protein and source of functional food. Ten soybean promising lines were characterized for its agronomic characters and nutrition contents (protein, lipid, and isoflavone) in eight soybean production centers in Indonesia on 2012. Soybean lines of K/IAC100-64-1004-1037, K/IAC100-997-1035, and IAC100/K-60-1092-1141 have total isoflavone 398.50 ppm, 396.69 ppm, and 394.77 ppm, respectively. The seed yield were 2.70 – 2.82 t/ha, protein content from 34.79 – 37.44%, lipid content from 17.34 – 19.18%, seed weight from 11.53 – 15.33 g, and the days to maturity of 83 days. These lines prospective to be released as high yielding and high isoflavone soybean varieties in Indonesia.
