  In a supersymmetric model where R-Parity and lepton number are violated
bilinearly in the superpotential, which can explain the solar and atmospheric
neutrino problems, we study the unification of gauge and Yukawa couplings at
the GUT scale. We show that bottom-tau Yukawa coupling unification can be
achieved at any value of $\tan\beta$, and that the strong coupling constant
prediction from unification of gauge couplings is closer to the experimental
value compared with the MSSM. We also study the predictions for $V_{cb}$ in a
Yukawa texture ans\"atze.
