Abstract: Let $ E$ be an ample and spanned vector bundle of rank $ r$ over a complex projective surface $ S$. It is shown that the sectional genus $ g(S,\det E)$ is bounded from below by the number $ b = \max \{ q(S),2 - r\chi ({\mathcal{O}_S})\} $ and pairs $ (S,E)$ satisfying $ b \leqslant g(S,\det E) \leqslant b + 1$ are characterized.
