## Abstract

According to the invention, there is provided an inbred corn line, designated PHP38. This invention thus relates to the plants and seeds of inbred corn line PHP38 and to methods for producing a corn plant produced by crossing the inbred line PHP38 with itself or with another corn plant. This invention further relates to hybrid corn seeds and plants produced by crossing the inbred line PHP38 with another corn line or plant and to crosses with related species.

## Claims

### Claim 1

A process to produce a hybrid corn seed which gives rise to a hybrid corn plant having alleles which, when expressed, contribute to drought tolerance, stability of yield, very good stay green, and good stalk strength, comprising the steps of:
(a) cultivating plants of corn inbred lines PHP38, representative seed having been deposited under ATCC Accession No. 75612, and another inbred line, not PHP38, said plants having male and female reproductive systems;
(b) prior to pollination, inactivating the male reproductive system of the plants of one of the inbred lines;
(c) cross pollinating the inbred lines; and
(d) harvesting seeds produced on the plants having inactivated male reproductive systems.

### Claim 2 (depends on 1)

A hybrid plant, and its parts, having alleles which, when expressed, contribute to drought tolerance, stability of yield, very good stay green, and good stalk strength, grown from seed resulting from the process of claim 1.

### Claim 3

Hybrid seed produced by:
(a) cultivating plants of corn inbred lines PHP38, representative seed having been deposited under ATCC Accession No. 75612, and another inbred line, not PHP38, said plants having male and female reproductive systems;
(b) prior to pollination, inactivating the male reproductive system of the plants of one of the inbred lines;
(c) cross pollinating the inbred lines; and
(d) harvesting seeds produced on the plants having inactivated male reproductive systems.

### Claim 4 (depends on 3)

A hybrid plant, and its parts, having alleles which, when expressed, contribute to drought tolerance, stability of yield, very good stay green, and good stalk strength, grown from seed of claim 3.

### Claim 5

Parts of a corn plant produced by seed designated PHP38 and having ATCC Accession No. 75612.

### Claim 6

Parts of a corn plant having all the physiological and morphological characteristics of the corn inbred line PHP38. seed of which have been deposited under ATCC Accession No. 75612.
