Abstract

A novel sweet corn hybrid plant, designated HMX4355YS, HMX4365YS, HMX4367WS and/or HMX5388YS is disclosed. The invention relates to the seeds of sweet corn hybrid HMX4355YS, HMX4365YS, HMX4367WS and/or HMX5388YS, to the plants and plant parts of sweet corn hybrid HMX4355YS, HMX4365YS, HMX4367WS and/or HMX5388YS, and to methods for producing a sweet corn plant by crossing the sweet corn hybrid HMX4355YS, HMX4365YS, HMX4367WS and/or HMX5388YS with itself or another sweet corn plant. The invention further relates to methods for producing a sweet corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other sweet corn plants derived from the sweet corn hybrid plant HMX4355YS, HMX4365YS, HMX4367WS and/or HMX5388YS.

First claim

What is claimed is:

1. A seed of sweet corn hybrid designated HMX4367WS, wherein a representative sample of seed of said hybrid has been deposited under NCIMB No. 42796.

2. A sweet corn plant, a part thereof, or a plant cell thereof, produced by growing the seed of claim 1 , wherein a plant regenerated from the part or the plant cell has all of the physiological and morphological characteristics of the plant of HMX4367WS listed in Table 3 when grown under the same environmental conditions.

3. The sweet corn plant, a part thereof, or a plant cell of claim 2 , wherein the sweet corn part is selected from the group consisting of: a leaf, a flower, an ear, and a kernel.

4. A sweet corn plant, or a part, or a plant cell thereof, wherein the plant or a plant regenerated from the part or the plant cell has all of the physological and morphological characteristicts of hybrid HMX4367WS listed in Table 3 when grown under the same environemental conditions, wherein a representative sample of seed of HMX4367WS has been deposited under NCIMB No. 42796.

5. A tissue culture of regenerable cells produced from the plant or plant part of claim 2 ,
wherein a plant regenerated from the tissue culture has all of the physiological and morphological characteristics of hybrid HMX4367WS listed in Table 3 when grown under the same environmental conditions, and wherein a representative sample of seed of said hybrid having been deposited under NCIMB No. 42796.

6. A protoplast produced from the tissue culture of claim 5 , wherein a plant regenerated from the protoplast has all of the physiological and morphological characteristics of hybrid HMX4367WS listed in Table 3 when grown under the same environmental conditions.

7. A sweet corn plant regenerated from the tissue culture of claim 5 , said plant having all of the physiological and morphological characteristics of hybrid HMX4367WS listed in Table 3 when grown under the same environmental conditions, wherein a representative sample of seed of said hybrid having been deposited under NCIMB No. 4276.

8. A sweet corn ear produced from the plant of claim 2 , wherein the sweet corn ear has all of the physiological and morphological characteristics of the corn ear of hybrid HMX4367WS when grown under the same environmental conditions.

9. A method for harvesting a sweet corn ear comprising a) growing the sweet corn plant of claim 2 to produce a sweet corn ear, and b) harvesting said sweet corn ear.

10. A sweet corn ear produced by the method of claim 9 , wherein the sweet corn ear has all the physiological and morphological characteristics of the ear of hybrid HMX4367WS when grown under the same environmental conditions.

11. A method for producing a sweet corn seed comprising crossing a first parent sweet corn plant with a second parent sweet corn plant and harvesting the resultant sweet corn seed, wherein said first parent sweet corn plant and/or second parent sweet corn plant is the sweet corn plant of claim 2 .

12. A method for producing a sweet corn seed comprising self-pollinating the sweet corn plant of claim 2 and harvesting the resultant sweet corn seed.

13. A method of producing a sweet corn plant derived from the hybrid variety HMX4367WS, the method comprising self-pollinating the plant of claim 2 at least once to produce a progeny plant derived from the variety HMX4367WS.

14. The method of claim 13 further comprising the step of:
(a) crossing the progeny plant derived from the variety HMX4367WS with itself or a second corn plant to produce a seed of progeny plant of a subsequent generation;
(b) growing the progeny plant of the subsequent generation from the seed and crossing the progeny plant of the subsequent generation with itself or a second corn plant and (c) repeating steps (a) or (b) for at least 1 generation to produce a sweet corn plant further derived from the sweet corn hybrid variety HMX4367WS.

15. A method of producing a sweet corn plant derived from the hybrid variety HMX4367WS, the method comprising crossing the plant of claim 2 with a second corn plant to produce a progeny plant derived from the variety HMX4367WS.

16. The method of claim 15 further comprising the step of:
(a) crossing the progeny plant derived from the variety HMX4367WS with itself or a second corn plant to produce a seed of progeny plant of a subsequent generation;
(b) growing the progeny plant of the subsequent generation from the seed and crossing the progeny plant of the subsequent generation with itself or a second corn plant and (c) repeating step (a) or (b) for at least 1 generation to produce a sweet corn plant further derived from the sweet corn hybrid variety HMX4367WS.

17. A method for producing a transgenic sweet corn plant, the method comprising crossing the sweet corn plant of claim 2 with a second corn plant containing a transgene, wherein the transgene of said second corn plant is integrated into the genome of the sweet corn plant progeny resulting from said cross, and wherein the transgene confers said sweet corn plant progeny with at least one trait selected from the group consisting of male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, increased sweetness, increased sugar content, increased flavor, water stress tolerance, heat stress tolerance, improved ripening control, and improved salt tolerance.

18. A method for producing a transgenic sweet corn plant, the method comprising transforming at least one transgene into a sweet corn HMX4367WS plant, or a plant part or a plant cell thereof or parental line used for producing the sweet corn hybrid plant HMX4367WS, a sample seed of said hybrid having been deposited under NCIMB No. 42796WS thereby producing a transgenic sweet corn plant.

19. A plant produced by the method of claim 18 , wherein the plant comprises a trait conferred by the transgene in the plant, and otherwise has all of the physiological and morphological characteristics of hybrid HMX4367WS listed in Table 3 when grown under the same environmental conditions.

20. The plant of claim 2 , wherein said plant further comprises a transgene.

21. The plant of claim 20 wherein the transgene confers said plant with a trait selected from the group consisting of male sterility, male fertility, herbicide resistance, insect resistance, disease resistance, increased sweetness, increased sugar content, increased flavor, water stress tolerance, heat stress tolerance, improved ripening control, and improved salt tolerance compared to hybred HMX4367WS wher grown under the same enviornmental conditions.

22. The plant of claim 2 comprising at least one single locus conversion, wherein the plant comprises a trait conferred by the single locus conversion in the plant, and otherwise has all of the physiological and morphological characteristics of hybrid HMX4367WS listed in Table 3 when grown under the same environmental conditions.

23.
