In scenarios with relatively light down squarks, motivated, e.g., by SO(10) D terms, jets + missing $E_T$ signals can be observed at the luminosity upgraded Tevatron even if the squarks are much heavier than the gluinos and the common gaugino mass ($M_{{1/2}}$) at $M_G$ lies above the LEP allowed lower bound. In the conventional mSUGRA model with heavy squarks practically no signal is expected in this channel. The possiblity of distinguishing between various SUGRA motivated scenarios by exploiting the missing $E_T$ and jet $p_T$ distributions, opposite sign dileptons + jets + missing $E_T$ events and clean trilepton signals have been discussed.
