For any 3-manifold formula12 and any nonnegative integer formula14, we give here examples of metrics on M each of which has a sequence of embedded minimal surfaces of genus formula14 and without Morse index bounds. On any spherical space form formula20 we construct such a metric with positive scalar curvature. More generally we construct such a metric with formula22 (and such surfaces) on any 3-manifold which carries a metric with formula22.
