The baryon-strangeness correlation in the hadronization of the quark matteris studied within the quark combination mechanism. We calculate the correlationcoefficient $C_{BS} = -3\big(\langle B S \rangle -\langle B\rangle \langleS\rangle\big)/\big( \langle S^2 \rangle-\langle S \rangle^2 \big)$ of initialhadrons produced from the deconfined free quark system with $C^{(q)}_{BS}=1$.The competition of the production of baryons against that of mesons is the keydynamics that is most relevant to the change of baryon-strangeness correlationduring system hadronization. Results of quark combination under the Poissonstatistics agree with the statistical model predictions for a hadron resonancegas at vanishing chemical potential but differ from those at relatively largechemical potentials. Results beyond Poisson statistics are also obtained andare compared with calculations of Lattice QCD in the phase boundary, giving thebest agreement at temperature $T =163$ MeV. We predict the dependence of the$C_{BS}$ of hadron system on the baryon chemical potential and strangeness.These predictions are expected to be tested by the future Lattice QCDcalculations at non-zero chemical potentials and/or by the Beam Energy Scanexperiment of STAR Collaboration at RHIC.
