The upper critical field {ital H}{sub {ital c}2}({ital T}) of the heavy fermion superconductor UPt{sub 3} for a magnetic field applied in the basal plane has been studied down to 150 mK and under hydrostatic pressure up to 10 kbar. The kink already observed in {ital H}{sub {ital c}2}({ital T}) at ambient pressure disappears by applying a relatively low pressure. This suggests that the high-temperature low-field superconducting phase reported recently is rapidly suppressed by pressure. A possible interpretation of these results is discussed in connection with recent theories.
