4. The part of the plant as claimed in claim 3 , wherein said part comprises a microspore, pollen, ovary, ovule, embryo sac or egg cell.

5. A part of the plant of claim 1 , wherein said part of the plant is suitable for vegetative reproduction.

6. The part of the plant as claimed in claim 5 , wherein said part comprises a cutting, root, stem, cell or protoplast.

7. A tissue culture of regenerable cells or protoplasts from the spinach plant of claim 1 .

8. A tissue culture as claimed in claim 7 , wherein said cells or protoplasts of the tissue culture are derived from a tissue comprising a leaf, pollen, embryo, cotyledon, hypocotyl, meristematic cell, root, root tip, anther, flower, seed or stem.

9. A spinach plant produced by transforming the spinach plant of claim 1 with a transgene.

10. A method of producing an inbred spinach plant derived from hybrid spinach variety 51-707 RZ, comprising the steps:

a) preparing a progeny plant derived from hybrid spinach variety 51-707 RZ by crossing the plant of claim 1 with a second spinach plant;

b) crossing the progeny plant with itself or a second spinach plant to produce a seed of a progeny plant of a subsequent generation;

c) growing a progeny plant of a subsequent generation from said seed and crossing the progeny plant of a subsequent generation with itself or a second spinach plant; and

d) repeating step b) and c) for at least 1 more generation to produce an inbred spinach plant derived from the hybrid spinach variety 51-707 RZ.

11. The method of claim 10 further comprising selecting at steps a), c) and d), an inbred spinach plant exhibiting at least one or more of the traits including early bolting in accordance with the UPOV TG/55/7 Form definition, erect plant habit, semi-savoy leaves, and resistance against downy mildew ( Peronospora farinosa f sp. spinaciae ) races Pfs1 to Pfs 13 and strain UA4410.

12. A method for producing spinach leaves comprising: (a) obtaining a plant according to claim 1 , wherein the plant has been cultivated to obtain leaves; and (b) harvesting the spinach leaves from the plant to thereby obtain harvested spinach leaves.

13. The method of claim 12 further comprising packaging the harvested spinach leaves as a fresh vegetable.

14. The method of claim 12 further comprising processing the harvested spinach leaves as a processed food.

15. A container comprising one or more spinach plants of claim 1 for the harvest of leaves.

16. A method for producing a seed of a 51-707 RZ-derived spinach plant comprising (a) crossing a plant of spinach variety 51-707 RZ, representative seed of which having been deposited under NCIMB Accession No. 41984, with a second spinach plant, and (b) whereby seed of a 51-707 RZ-derived spinach plant forms.

17. The method of claim 16 further comprising (c) crossing a plant grown from 51-707 RZ-derived spinach seed with itself or with a second spinach plant to yield additional 51-707 RZ-derived spinach seed, (d) growing the additional 51-707 RZ-derived spinach seed of step (c) to yield additional 51-707 RZ-derived spinach plants, and (e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to generate further 51-707 RZ-derived spinach plants.

18. The method of claim 17 further comprising selecting at steps a), c), and e), a 51-707 RZ-derived spinach plant, exhibiting a combination of traits including early bolting in accordance with the UPOV TG/55/7 Form definition, erect plant habit, semi-savoy leaves, and resistance against downy mildew ( Peronospora farinosa f sp. spinaciae ) races Pfs1 to Pfs13 and strain UA4410.

19. A method of determining the genotype of a plant of spinach variety 51-707 RZ, representative seed of which has been deposited under NCIMB Accession No. 41984, or a first generation progeny thereof, comprising obtaining a sample of nucleic acids from said plant and comparing said nucleic acids to a sample of nucleic acids obtained from a reference plant, and detecting a plurality of polymorphisms between the two nucleic acid samples, wherein the plurality of polymorphisms are indicative of spinach variety 51-707 RZ and/or give rise to the expression of any one or more, or all, of the morphological and physiological characteristics of spinach variety 51-707 RZ as claimed in claim 1 .

20. The method of claim 19 additionally comprising the step of storing the results of detecting the plurality of polymorphisms on a computer readable medium, or transmitting the results of detecting the plurality of polymorphisms.

21. The spinach plant of claim 1 , which is a plant grown from seed having been deposited under NCIMB Accession No. 41984.

22. A spinach plant having all the morphological and physiological characteristics of the spinach plant of claim 1 .

23. A seed capable of growing into the spinach plant of claim 1 .
