## Abstract

A novel inbred maize line designated PHADP and seed, plants and plant parts thereof. Methods for producing a maize plant that comprise crossing inbred maize line PHADP with another maize plant. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into PHADP through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced thereby. Hybrid maize seed, plant or plant part produced by crossing the inbred line PHADP or an introgressed trait conversion of PHADP with another maize line. Inbred maize lines derived from inbred maize line PHADP, methods for producing other inbred maize lines derived from inbred maize line PHADP and the inbred maize lines and their parts derived by the use of those methods.

(b) selecting F1 progeny plants that have the desired trait to produce selected F1 progeny plants;
(c) crossing the selected progeny plants with the PHADP plants to produce backcross progeny plants;
(d) selecting for backcross progeny plants that have the desired trait and the alleles of inbred line PHADP at the SSR loci listed in Table 2 to produce selected backcross progeny plants; and
(e) repeating steps (c) and (d) to produce backcross progeny plants that comprise the desired trait and comprise at least 95% of the alleles of inbred line PHADP at the SSR loci listed in Table 2.

### Claim 12 (depends on 11)
