  We have experimentally produced rubidium Bose-Einstein condensate in an
optically-plugged magnetic quadrupole (OPQ) trap. A far blue-detuned focused
laser beam with a wavelength of 532 nm is plugged in the center of the magnetic
quadrupole trap to increase the number of trapped atoms and suppress the
heating. A radio frequency (RF) evaporative cooling in the magneto-optical
hybrid trap is applied to decrease the atom temperature into degeneracy. The
atom number of the condensate is $1.2(0.4)\times10^5$ and the temperature is
below 100 nK. We have also studied characteristic behaviors of the condensate,
such as phase space density (PSD), condensate fraction and anisotropic
expansion.
