  In the paper we first construct rational solutions for the
Nijhoff-Quispel-Capel (NQC) equation by means of bilinear method. These
solutions can be transferred to those of Q3$_\delta$ equation in the
Adler-Bobenko-Suris (ABS) list. Then making use of degeneration relation we
obtain rational solutions for Q2, Q1$_\delta$, H3$_\delta$, H2 and H1. These
rational solutions are in Casoratian form and the basic column vector satisfies
an extended condition equation set.
