Abstract

An inbred corn line, designated 4HSXI1003, the plants and seeds of the inbred corn line 4HSXI1003, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line 4HSXI1003 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line 4HSXI1003 with another corn line or plant and to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic corn plants produced by that method. This invention also relates to inbred corn lines derived from inbred corn line 4HSXI1003, to methods for producing other inbred corn lines derived from inbred corn line 4HSXI1003 and to the inbred corn lines derived by the use of those methods.

Claims

1. A seed of corn inbred line designated 4HSXI1003, or a part thereof, representative seed of the line having been deposited under ATCC Accession No. PTA-124407.

2. The seed part of claim 1 selected from the group consisting of pericarp, germ and endosperm.

3. The seed of claim 1 further comprising a seed treatment on the surface of the seed.

4. A corn plant produced by growing the seed of claim 1.

5. A plant part of the corn plant of claim 4, the plant part selected from the group consisting of an intact plant cell, a plant protoplast, an embryo, a pollen, an ovule, a flower, a kernel, a seed, an ear, a cob, a leaf, a husk, a stalk, a root, a root tip, a brace root, a lateral tassel branch, an anther, a tassel, a glume, a tiller and a silk.

6. A pollen or an ovule of the plant of claim 4.

7. A corn plant having all the physiological and morphological characteristics of the corn plant of claim 4.

8. A method for producing a corn seed, the method comprising (a) crossing the plant of claim 4, with another different corn plant to yield progeny corn seed.

9. The method of claim 8, wherein the other, different corn plant is an inbred corn plant.

10. The method of claim 8, further comprising:

(b) growing the progeny corn seed from step (a) under self-pollinating or sib-pollinating conditions for about 5 to about 7 generations; and

(c) harvesting resultant seed.

11. A method of introducing a desired trait into corn inbred line 4HSXI1003, representative seed of the line having been deposited under ATCC Accession No. PTA-124407, the method comprising:

(a) crossing 4HSXI1003 plants of another corn line that comprises a desired trait to produce F₁ progeny plants;

(b) selecting F₁ progeny plants;

(c) crossing F1 progeny plants that have the desired trait with 4HSXI1003 plants to produce backcross progeny plants;

(d) selecting for backcross progeny plants that comprise the desired trait and physiological and morphological characteristics of corn inbred line 4HSXI1003; and

(e) performing further backcrosses of each generation of selected backcross progeny plants with 4HSXI1003 plants sufficient times in succession to produce higher backcross progeny plants that comprise the desired trait and otherwise all of the physiological and morphological characteristics of corn inbred line 4HSXI1003 as determined at the 5% significance level when grown in the same environmental conditions.

12. An inbred corn line comprising the desired trait produced by the method of claim 11.

13. A seed of corn inbred line 4HSXI1003 further comprising a transgene that is inherited by the seed, wherein a sample of corn inbred line 4HSXI1003 has been deposited under ATCC Accession No. PTA-124407.

14. The seed of claim 13, wherein the transgene confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, waxy starch, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

15. A plant grown from the seed of claim 13.

16. An F1 hybrid seed produced by crossing the plant of claim 15 with another different corn plant.

17. The F1 hybrid seed of claim 16, further comprising a seed treatment on the surface of the seed.

18. An F1 hybrid plant grown from the seed of claim 16, or a plant part thereof, the plant part comprising at least one cell of the F1 hybrid plant.

19. A method of producing a commodity plant product comprising starch, syrup, silage, fat or protein, the method comprising producing the commodity plant product from the plant or plant part of claim 18.

20. A method for producing a second maize plant, the method comprising crossing the maize plant or plant part of claim 18 with itself or with a different maize plant.
