Abstract

A soybean variety designated 92B56, the plants and seeds of soybean variety 92B56, methods for producing a soybean plant produced by crossing the variety 92B56 with itself or with another soybean plant, and hybrid soybean seeds and plants produced by crossing the variety 92B56 with another soybean line or plant, and the creation of variants by mutagenesis or transformation of variety 92B56. This invention also relates to methods for producing other soybean varieties or breeding lines derived from soybean variety 92B56 and to soybean varieties or breeding lines produced by those methods.

obtaining the soybean plant, or its parts, of claim 2 and;

p1 employing said plant or parts as a source of breeding material using plant breeding techniques.

9. The method of claim 8 wherein said plant breeding techniques are selected from the group consisting of:

recurrent selection, mass selection, bulk selection, backcrossing, pedigree breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, and transformation.

10. A method for producing a first generation hybrid soybean seed comprising:

crossing the plant of claim 2 with a different inbred parent soybean plant, and harvesting the resultant first generation hybrid soybean seed.

11. An F₁ hybrid soybean seed produced by the method of claim 10.

12. The method of claim 10 for producing a first generation hybrid soybean seed wherein the inbred soybean plant of claim 2 is the female parent.

13. The method of claim 10 for producing a first generation hybrid soybean seed wherein the inbred soybean plant of claim 2 is the male parent.

14. The soybean plant, or parts thereof, of claim 2, wherein the plant or parts thereof have been transformed so that its genetic material contains one or more transgenes.

15. A method for producing a soybean plant that contains in its genetic material one or more transgenes, comprising crossing the soybean plant of claim 14 with either a second plant of another soybean line, or a non-transformed soybean plant of the soybean variety 92B56, so that the genetic material of the progeny that result from the cross contains the transgene.

16. an plant or parts thereof, produced by the method of claim 15.

17. An F₁ hybrid soybean seed plant, or parts thereof, grown from seed of the plant of claim 16.

18. A method for developing a soybean plant in a soybean breeding program comprising:

obtaining the soybean plant, or its parts, of claim 14 and;

employing said plant or parts as a source of breeding material using plant breeding techniques.

19. The method of claim 18 wherein plant breeding techniques are selected from the group consisting of:

recurrent selection, mass selection, bulk selection, backcrossing, pedigree breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, and transformation.

20. A soybean plant, or parts thereof, having all the physiological and morphological characteristics of the plant of claim 2.

21. The soybean plant part of claim 20 wherein said part is pollen.

22. The soybean plant part of claim 20 wherein said part is an ovule.

23. A tissue culture of regenerable cells from the plant of claim 20.

24. A tissue culture according to claim 23, the cells or protoplasts of the tissue culture being of a tissue selected from the group consisting of:

leaf, pollen, cotyledon, hypocotyl, embryos, root, pod, flower, shoot and stalk.

25. A soybean plant regenerated from the tissue culture of claim 23, capable of expressing all the morphological and physiological characteristics of soybean variety 92B56, representative seed of said soybean variety 92B56 having been deposited under ATCC Accession No. PTA-3565.
