Abstract We prove a higher genus version of the genus 00 local-relative correspondence of van Garrel-Graber-Ruddat: for (X,D)(X,D) a pair with X a smooth projective variety and D a nef smooth divisor, maximal contact Gromov-Witten theory of (X,D)(X,D) with λg\lambda _g -insertion is related to Gromov-Witten theory of the total space of OX(−D){\mathcal O}_X(-D) and local Gromov-Witten theory of D . Specializing to (X,D)=(S,E)(X,D)=(S,E) for S a del Pezzo surface or a rational elliptic surface and E a smooth anticanonical divisor, we show that maximal contact Gromov-Witten theory of (S,E)(S,E) is determined by the Gromov-Witten theory of the Calabi-Yau 3-fold OS(−E){\mathcal O}_S(-E) and the stationary Gromov-Witten theory of the elliptic curve E . Specializing further to S=P2S={\mathbb P}^2 , we prove that higher genus generating series of maximal contact Gromov-Witten invariants of (P2,E)({\mathbb P}^2,E) are quasimodular and satisfy a holomorphic anomaly equation. The proof combines the quasimodularity results and the holomorphic anomaly equations previously known for local P2{\mathbb P}^2 and the elliptic curve. Furthermore, using the connection between maximal contact Gromov-Witten invariants of (P2,E)({\mathbb P}^2,E) and Betti numbers of moduli spaces of semistable one-dimensional sheaves on P2{\mathbb P}^2 , we obtain a proof of the quasimodularity and holomorphic anomaly equation predicted in the physics literature for the refined topological string free energy of local P2{\mathbb P}^2 in the Nekrasov-Shatashvili limit.
