The Konno invariant of a projective varietyXis the minimum geometric genus of the fiber of a rational pencil onX. It was computed by Konno for surfaces in, and in general can be viewed as a measure of the complexity ofX. We estimatefor some natural classes of varieties, including sharp asymptotics for polarized K3 surfaces. In an appendix, we give a quick proof of a classical formula due to Deligne and Hoskin for the colength of an integrally closed ideal on a surface.
