## Abstract

The present invention relates to a Diplotaxis tenuifolia seed designated 89-001 RZ, which exhibits a combination of traits including downy mildew resistance, medium to dark grey green leaves, high leaf thickness and very narrow primary lobes. The present invention also relates to a Diplotaxis tenuifolia plant produced by growing the 89-001 RZ seed. The invention further relates to methods for producing the wild rocket cultivar, represented by wild rocket variety 89-001 RZ.

## Claims

### Claim 1

### Claim 2 (depends on 1)

A plant grown from the seed of claim 1.

### Claim 3 (depends on 2)

The wild rocket plant of claim 2, which is a plant grown from seed having been deposited under NCIMB Accession No. 42516.

### Claim 4 (depends on 2)

A wild rocket plant, or a part thereof, having all the physiological and morphological characteristics of the wild rocket plant of claim 2.

### Claim 5 (depends on 4)

A part of the plant of claim 4, wherein said part is a microspore, pollen, an ovary, an ovule, an embryo sac or an egg cell, a cutting, a root, a stem, a cell or a protoplast.

### Claim 6 (depends on 4)

A tissue culture of regenerable cells or protoplasts from the wild rocket plant or plant part of claim 4.

### Claim 7 (depends on 6)

The tissue culture as claimed in claim 6, wherein said cells or protoplasts of the tissue culture are derived from a leaf, pollen, an embryo, a cotyledon, a hypocotyl, a meristematic cell, a root, a root tip, an anther, a flower, a seed or a stem.

### Claim 8 (depends on 6, 7)

A wild rocket plant regenerated from the tissue culture of claim 6 or 7, wherein the regenerated plant expresses all of the physiological and morphological characteristics of wild rocket variety 89-001 RZ a sample of seed of said variety having been deposited under NCIMB Accession No. 42516.

### Claim 9

A method of vegetatively propagating a plant of wild rocket variety 89-001 RZ comprising (a) collecting tissue capable of being propagated from a plant of wild rocket 89-001 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 42516, and (b) producing a rooted plant from said tissue.

### Claim 10 (depends on 2)

A method of producing a wild rocket seed comprising crossing a male parent wild rocket plant with a wild rocket parent plant and harvesting the resultant wild rocket seed, wherein said male parent wild rocket plant and/or said female parent wild rocket plant is the wild rocket plant of claim 2.

### Claim 11 (depends on 10)

A wild rocket seed produced by the method of claim 10.

### Claim 12 (depends on 11)

A wild rocket plant produced by growing the seed of claim 11.

### Claim 13

A method for producing a seed of a 89-001 RZ-derived wild rocket plant comprising (a) crossing a plant of wild rocket variety 89-001 RZ, representative seed of which having been deposited under NCIMB Accession No. 42516, with a second wild rocket plant, and (b) whereby seed of a 89-001 RZ-derived wild rocket plant forms.

### Claim 14 (depends on 13)

The method of claim 13 further comprising (c) crossing a plant grown from 89-001 RZ-derived wild rocket seed with itself or with a second wild rocket plant to yield additional 89-001 RZ-derived wild rocket seed, (d) growing the additional 89-001 RZ-derived wild rocket seed of step (c) to yield additional 89-001 RZ-derived wild rocket plants, and (e) repeating the crossing and growing of steps (c) and (d) for an additional 3-10 generations to generate further 89-001 RZ-derived wild rocket plants, and (f) whereby seed of a 89-001 RZ-derived wild rocket plant forms.

### Claim 15 (depends on 13, 14)

A seed produced by the method of claim 13 or 14.

### Claim 16

A method of introducing at least one new trait into a plant of wild rocket variety 89-001 RZ comprising: (a) crossing a plant of wild rocket variety 89-001 RZ, representative seed of which having been deposited under NCIMB Accession No. 42516, with a second wild rocket plant that comprises at least one new trait to produce progeny seed; (b) harvesting and planting the progeny seed to produce at least one progeny plant of a subsequent generation, wherein the progeny plant comprises the at least one new trait; (c) crossing the progeny plant with a plant of wild rocket variety 89-001 RZ to produce backcross progeny seed; (d) harvesting and planting the backcross progeny seed to produce a backcross progeny plant; and (e) repeating steps (c) and (d) for at least three additional generations to produce a wild rocket plant of variety 89-001 RZ comprising at least one new trait and all of the physiological and morphological characteristics of a plant of wild rocket variety 89-001 RZ, when grown in the same environmental conditions.

### Claim 17

A method of producing a plant of wild rocket variety 89-001 RZ comprising at least one new trait, the method comprising introducing a mutation or transgene conferring the at least one new trait into a plant of wild rocket variety 89-001 RZ, wherein a sample of seed of said variety has been deposited under NCIMB Accession No. 42516.

### Claim 18 (depends on 16, 17)

The wild rocket plant produced by the method of claim 16 or 17.

### Claim 19 (depends on 1)

A method for producing wild rocket leaves as food product comprising sowing the seed of a claim 1 and growing the seed into a harvestable wild rocket plant and harvesting the leaves of said plant.

### Claim 20 (depends on 2)

A method for producing wild rocket leaves as a fresh vegetable comprising packaging leaves of a plant of claim 2.

### Claim 21 (depends on 2)
