Abstract

The invention provides seed and plants of the hybrid corn variety designated 61729545. The invention thus relates to the plants, seeds and tissue cultures of the variety 61729545, and to methods for producing a corn plant produced by crossing a corn plant of variety 61729545 with itself or with another corn plant, such as a plant of another variety. The invention further relates to genetic complements of plants of variety 61729545.

Claims

1. A seed of the hybrid corn variety 61729545, produced by crossing a first plant of variety SLB01 with a second plant of variety 3KKXX0202, wherein representative seed of said varieties SLB01 and 3KKXX0202 have been deposited under ATCC Accession numbers PTA-9806 and PTA-124385, respectively.

2. A plant grown from the seed of claim 1, or a plant part thereof comprising at least one cell of hybrid corn variety 61729545.

5. A method of producing the hybrid corn seed of claim 1, the method comprising crossing the first plant of variety SLB01 with the second plant of variety 3KKXX0202.

6. A method for producing corn grain, the method comprising growing the plant of claim 2 until grain is produced and collecting the grain.

7. A method of introducing a desired trait into hybrid corn seed of claim 1, the method comprising the steps of:

(a) introducing by introgression or transformation a transgene conferring the desired trait into a variety selected from the group consisting of inbred SLB01 and inbred 3KKXX0202 to produce a transgenic inbred plant of SLB01 or 3KKXX0202, the transgenic inbred plant heritably carrying the trait, wherein representative seed of the varieties SLB01 and 3KKXX0202 have been deposited under ATCC Accession Numbers PTA-9806 and PTA-124385, respectively; and

(b) crossing the transgenic inbred plant or an isogenic progeny plant thereof with (i) a plant of the other inbred corn variety or (ii) a plant of the other inbred corn variety further comprising a transgenic trait to produce seed of the hybrid corn variety 61729545 that heritably carries and expresses the transgene and produces a hybrid plant that comprises (i) the transgene or (ii) the transgene and the transgenic trait, wherein the hybrid plant otherwise comprises all of the morphological and physiological characteristics of hybrid corn variety 61729545 when grown under the same environmental conditions.

8. The method of claim 7, wherein the desired trait is 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.

9. A hybrid plant produced by the method of claim 7.

10. A method of producing a corn plant derived from the hybrid corn variety 61729545, the method comprising crossing the plant of claim 2 with a second corn plant to produce a progeny corn plant derived from the hybrid corn variety 61729545.

17. The method of claim 7, wherein the transgene is introduced by introgression in step (a).

18. The method of claim 7 wherein said desired trait is 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.

19. The method of claim 7 further comprising repeating step (a) at least once to introduce at least a second desired trait into hybrid corn variety 61729545, wherein the second desired trait is 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.

3. A seed of the hybrid corn variety 61729545 further comprising a single locus conversion, wherein a plant grown from said seed comprises a trait conferred by said single locus conversion, and wherein said seed is produced by crossing a first plant of variety SLB01 with a second plant of variety 3KKXX0202, wherein the first plant, the second plant, or both further comprise the single locus conversion, and wherein representative seeds of the varieties SLB01 and 3KKXX0202 are deposited under ATCC Accession Nos. PTA-9806 and PTA-124385, respectively.

4. The seed of claim 3, wherein the single locus conversion confers a trait selected from the group consisting of male sterility, herbicide tolerance, insect resistance, disease resistance, modified fatty acid metabolism, modified phytic acid metabolism, modified carbohydrate metabolism and modified protein metabolism.

11. A seed of hybrid maize variety 61729545 further comprising a transgene, wherein a plant grown from the seed comprises a trait conferred by the transgene, and wherein the seed is produced by crossing a first plant of variety SLB01 with a second plant of variety 3KKXX0202, wherein the transgene is introduced by backcrossing or genetic transformation into the variety SLB01, the variety 3KKXX0202, or both varieties SLB01 and 3KKXX0202, and wherein representative seed of the varieties SLB01 and 3KKXX0202 have been deposited under ATCC Accession Numbers PTA-9806 and PTA-124385, respectively.

12. The seed of claim 11, 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.

13. The seed of claim 11, further comprising a seed treatment on the surface of the seed.

14. A plant grown from the seed of claim 11, or a plant part thereof, the plant part comprising at least one cell of the hybrid maize variety 61729545 further comprising a transgene.

15. 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 14.

16. A method for producing a second maize plant, the method comprising crossing the maize plant or plant part of claim 14 with itself or with a different maize plant.

20. A method for producing a treated seed, the method comprising applying a seed treatment to the seed of claim 11 to coat the seed with the seed treatment.
