Abstract We present a critical review of the predictions of various nucleosynthetic models which may have some relevance to the elemental and isotopic cosmic-ray source composition. In particular, we compare the yields of the elements between Helium and Zinc expected from various supernova models with the bulk galactic cosmic-ray source elemental composition. On the other hand, the origin of the C, 22Ne, 25,26Mg (and possibly also 0 and 29,30Si) excess (with respect to solar system) inferred at the cosmic-ray sources is examined in the light of some specific scenarios, and especially in the framework of Wolf-Rayet star nucleosynthesis.
