The purpose of this note is to give the one loop radiative corrections to thetop quark pair production in the $p\bar{p}$ annihilation at the FermilabTevatron in the context of the Minimal Supersymmetric Model. We concentratehere on the supersymmetric QCD corrections and give the analytic expression forthese corrections. Recently Li et. al. have reported the supersymmetric QCDcorrections to this process we indicate clearly a comparison of their and ourwork. In particular, we find additional corrections [crossed box and gluonself-energy] at the one loop level which are not given by Li et. al.. Ournumerical results disagree with the original claim of Li et. al. The numericalvalues given by them in a recent erratum do agree with the general trend of ournumerical results however the actual values still disagree. We find that thepercentage corrections at the hadronic corrections changes from $22\%$ to$-0.5\%$ as the squark mass is changed from 100 GeV to 600 GeV, for a gluinomass of 200 GeV. For a gluino mass of 150 GeV the squark-mass dependence isless abrupt; they change from $-5.3\%$ to $1\%$ as the squark mass is variedbetween 100 GeV and 600 GeV. We also present numerical results for differentialcross section at the hadronic level, and percentage corrections at the partonlevel. PACS number(s): 14.80Dq; 12.38Bx; 14.80.
