Numerical models for the chemical evolution of the Galaxy have been computedwith the new stellar yields published by Maeder (1992). These metallicitydependent yields represent an important improvement in the chemical evolutionof galaxies but there are still uncertainties in the stellar evolution whichprevent completely satisfactory results. {}From the comparison of the modelpredictions with the corresponding observational constraints we find thatMaeder's nucleosynthesis reproduces the oxygen and carbon abundances andprovides consistent $\Delta$Y/$\Delta$(O/H) ratios if a significant amount ofgas is accreted by the galactic disc during its whole lifetime. The lower masslimit for the black hole formation (M$_{bh}$) must be larger than 22.5M$_{\odot}$ to avoid oxygen underproduction.
