Abstract
The quark flavor and spin distributions in octet baryons are calculated both in the SU(6) quark spectator diquark model and in a perturbative QCD (pQCD) based model. It is shown that the Lambda has the most significant difference in flavor structure at large x between the two models, though the flavor and spin structure of other baryons can also provide tests of different models. The Drell-Yan process for Sigma(+ -) beams on isoscalar targets can be used to test different predictions concerning the valence quark flavor structure of the Sigma(+ -).
