Let (X,H) be a polarized K3 surface with, and letbe a smooth curve of genusg. We give an upper bound on the dimension of global sections of a semistable vector bundle onC. This allows us to compute the higher rank Clifford indices ofCwith high genus. In particular, when, the rankrClifford index ofCcan be computed by the restriction of Lazarsfeld–Mukai bundles onXcorresponding to line bundles on the curveC. This is a generalization of the result by Green and Lazarsfeld for curves on K3 surfaces to higher rank vector bundles. We also apply the same method to the projective plane and show that the rankrClifford index of a degreesmooth plane curve is, which is the same as the Clifford index of the curve.
