Abstract

An inbred corn line, designated XHE21, the plants and seeds of the inbred corn line XHE21, methods for producing a corn plant, either inbred or hybrid, produced by crossing the inbred corn line XHE21 with itself or with another corn plant, and hybrid corn seeds and plants produced by crossing the inbred line XHE21 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 XHE21, to methods for producing other inbred corn lines derived from inbred corn line XHE21 and to the inbred corn lines derived by the use of those methods.

First claim

What is claimed is:

1. Seed of corn inbred line designated XHE21, or a part thereof, representative seed of the line having been deposited under ATCC Accession No. PTA-122518.

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

3. The seed of claim 1 , wherein the seed further comprises a coating.

4. A substantially homogenous population of the corn seeds of claim 1 .

5. A method for producing corn seed, comprising:
(a) planting seed of claim 1 ;
(b) growing a plant from the seed under pollinating conditions; and,
(c) harvesting seed produced by the plants grown in step (b).

6. Corn seed produced by the method of claim 5 .

7. The method of claim 5 , further comprising treating the growing plants or soil surrounding the growing plants with an agricultural chemical.

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

9. A part of the corn plant of claim 8 , 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.

10. Pollen of the plant of claim 8 .

11. An ovule of the plant of claim 8 .

12. A corn plant, or a part thereof, having all the physiological and morphological characteristics of the corn plant of claim 8 .

13. A substantially homogenous population comprising the corn plants of claim 8 .

14. A method for producing a corn plant, comprising:
(a) crossing inbred corn plant XHE21, representative seed of the line having been deposited under ATCC Accession No. PTA-122518, with another different corn plant to yield progeny corn seed.

15. The method of claim 14 , wherein the other, different corn plant is an inbred corn plant.

16. The method of claim 14 , 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.

17. The method of claim 14 , further comprising:
(a) growing at least one generation of the progeny corn seed; and
(b) selecting plants obtained from growing the at least one generation of the progeny corn seed for a desirable trait.

18. A method of introducing a desired trait into corn inbred line XHE21, representative seed of the line having been deposited under ATCC Accession No. PTA-122518, comprising:
(a) crossing XHE21 plants with plants of another corn line that comprise a desired trait to produce F 1 progeny plants;
(b) selecting F 1 progeny plants that have the desired trait;
(c) crossing selected progeny plants with XHE21 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 XHE21; and
(e) performing steps (c) and (d) at least three or more times in succession to produce the selected fourth and higher backcross progeny plants that comprise the desired trait and all of the physiological and morphological characteristics of corn inbred line XHE21 listed in Table 1 as determined at the 5% significance level when grown in the same environmental conditions.

19. A method for producing a hybrid corn seed comprising crossing a first inbred parent corn plant with a second inbred parent corn plant and harvesting resultant hybrid corn seed, wherein the first inbred corn plant or the second inbred corn plant is the corn plant of claim 8 .

20. A method for producing a hybrid corn seed, the method comprising:
(a) planting in pollinating proximity a seed of the corn plant of claim 8 and a seed of another, different corn plant;
(b) cultivating the seeds into plants that bear flowers;
(c) allowing cross pollination to occur between the cultivated plants; and
(d) harvesting seeds produced on at least one of the plants.

21. The method according to claim 20 , wherein the XHE21 corn plant is the male parent.

22. The method according to claim 20 , wherein the XHE21 corn plant is the female parent.

23. A hybrid corn seed produced by the method according to claim 20 .

24. A hybrid corn plant, or parts thereof, produced by growing the hybrid corn seed of claim 23 .
