Abstract： The property of σ-meson or f0 (400-1200) is studied in the general color symmetry model (GCM) for quantum chromodynamics. With recent determined values of mσ, fσ and fπ in GCM, the isoscalar ππ S-wave amplitude is calculated without any free parameter. The T-matrix pole for f0 (400-1200) is found to be 1011- i 284MeV, which is very close to the Particle Data Group value (400-1200)-i(300-500) MeV.
