We have performed a test of the conserved-vector-current hypothesis (CVC) by determining the baryon charges and magnetic moments from the hyperon semileptonic data. Then CVC was applied in order to make a joint fit of all baryon semileptonic decay data and baryon magnetic moments for the spectrum-generating-group (SG) model as well as for the conventional (Cabibbo and magnetic moments in nuclear magnetons) model. The SG model gives a very good fit with chi/sup 2//n/sub D/ = 25/20/sup triangle-open//sub 21% C.L. whereas the conventional model gives a fit with chi/sup 2//n/sub D/approx. =244/20.
