Abstract

According to the invention, there is provided an inbred corn plant designated 87DIA4. This invention thus relates to the plants, seeds and tissue cultures of the inbred corn plant 87DIA4, and to methods for producing a corn plant produced by crossing the inbred plant 87DIA4 with itself or with another corn plant, such as another inbred. This invention further relates to corn seeds and plants produced by crossing the inbred plant 87DIA4 with another corn plant, such as another inbred, and to crosses with related species. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant 87DIA4, and also to the RFLP and genetic isozyme typing profiles of inbred corn plant 87DIA4.

16. The inbred corn plant cell of claim 13, having an RFLP genetic marker profile and a genetic isozyme typing profile in accordance with the profiles shown in Tables 8 and 9.

17. The inbred corn plant cell of claim 13, located within a corn plant or seed.

18. The inbred corn plant of claim 4 having:

(a) an RFLP genetic marker profile in accordance with the profile shown in Table 8;

or

(b) a genetic isozyme typing profile in accordance with the profile shown in Table 9.

19. The inbred corn plant of claim 18, having an RFLP genetic marker profile in accordance with the profile shown in Table 8.

20. The inbred corn plant of claim 18, having a genetic isozyme typing profile in accordance with the profile shown in Table 9.

21. The inbred corn plant of claim 18, having an RFLP genetic marker profile and a genetic isozyme typing profile in accordance with the profiles shown in Tables 3 and 9.

7. An essentially homogeneous population of corn plants produced by growing the seed of an inbred corn plant designated 87DIA4, a sample of the seed of said corn plant having been deposited under ATCC Accession No. 203192.

8. A corn plant having all the physiological and morphological characteristics of corn plant 87DIA4, a sample of the seed of said corn plant having been deposited under ATCC Accession No. 203192.

9. The corn plant of claim 8, further comprising a cytoplasmic factor conferring male sterility.

29. The corn plant of claim 8, further comprising a single gene conversion.

30. The corn plant of claim 29, wherein the single gene was stably inserted into a corn genome by transformation.

31. The single gene conversion of the corn plant of claim 29, where the gene is a dominant allele.

32. The single gene conversion of the corn plant of claim 29, where the gene is a recessive allele.

33. The single gene conversion corn plant of claim 29, where the gene confers herbicide resistance.

34. The single gene conversion of the corn plant of claim 29, where the gene confers insect resistance.

35. The single gene conversion of the corn plant of claim 29, where the gene confers resistance to bacterial, fungal, or viral disease.
