## Abstract

The present invention relates to a Diplotaxis tenuifolia seed designated 89-WR019 RZ, which exhibits a combination of traits including non-shattering pods, a medium green colored leaf, a medium leaf division, and medium to late bolting. The present invention also relates to a Diplotaxis tenuifolia plant produced by growing the 89-WR019 RZ seed. The invention further relates to methods for producing the wild rocket cultivar, represented by wild rocket variety 89-WR019 RZ.

## Claims

### Claim 1

A seed of wild rocket variety 89-WR019 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44648.

### Claim 2 (depends on 1)

A wild rocket 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. 44648.

### 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 leaf, an embryo, a microspore, a cotyledon, a hypocotyl, a meristematic cell, a flower, pollen, an ovary, an ovule, an anther, an embryo sac, an egg cell, a cutting, a root, a root tip, a stem, a cell or a protoplast.

### Claim 6 (depends on 5)

A tissue culture of regenerable cells or protoplasts from the wild rocket plant or plant part of claim 5.

### Claim 7

(canceled)

### Claim 8 (depends on 6)

A wild rocket plant regenerated from the tissue culture of claim 6, wherein the regenerated plant expresses all of the physiological and morphological characteristics of wild rocket variety 89-WR019 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44648.

### Claim 9

(canceled)

### Claim 10 (depends on 2)

A method of vegetatively propagating a plant of wild rocket variety 89-WR019 RZ, a sample of seed of said variety having been deposited under NCIMB Accession No. 44648, comprising (a) collecting tissue from a wild rocket plant of claim 2, deposited and (b) producing a rooted plant from said tissue.

### Claim 11 (depends on 2)

A method of producing a wild rocket seed comprising crossing a male parent wild rocket plant with a female parent wild rocket 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 12 (depends on 11)

A wild rocket seed produced by the method of claim 11.

### Claim 13

(canceled)

### Claim 14

A method for producing a seed of an 89-WR019 RZ-derived wild rocket plant comprising (a) crossing a plant of wild rocket variety 89-WR019 RZ, representative seed of which having been deposited under NCIMB Accession No. 44648, with a second wild rocket plant, and (b) whereby seed of an 89-WR019 RZ-derived wild rocket plant forms.

### Claim 15 (depends on 14)

The method of claim 14 further comprising (c) crossing a plant grown from 89-WR019 RZ-derived wild rocket seed with itself or with a second wild rocket plant to yield additional 89-WR019 RZ-derived wild rocket seed, (d) growing the additional 89-WR019 RZ-derived wild rocket seed of step (c) to yield additional 89-WR019 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-WR019 RZ-derived wild rocket plants, and (f) whereby seed of an 89-WR019 RZ-derived wild rocket plant forms.

### Claim 16 (depends on 14)

A seed produced by the method of claim 14.

### Claim 17 (depends on 15)

A seed produced by the method of claim 15.

### Claim 18

A method of introducing at least one new trait into a plant of wild rocket variety 89-WR019 RZ comprising: (a) crossing a plant of wild rocket variety 89-WR019 RZ, representative seed of which having been deposited under NCIMB Accession No. 44648, 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-WR019 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-WR019 RZ comprising at least one new trait and all of the physiological and morphological characteristics of a plant of wild rocket variety 89-WR019 RZ, when grown in the same environmental conditions.

### Claim 19 (depends on 2)

A method of producing a plant of wild rocket variety 89-WR019 RZ comprising at least one new trait, the method comprising introducing a mutation or transgene conferring the at least one new trait into the wild rocket variety plant of claim 2.

### Claim 20

(canceled)

### Claim 21 (depends on 19)

The wild rocket plant produced by the method of claim 19.

### Claim 22 (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 23

(canceled)

### Claim 24

(canceled)

### Claim 25 (depends on 2)

A container comprising one or more wild rocket plants of claim 2 for harvest of leaves.

### Claim 26 (depends on 2)

A method of determining the genotype of a plant of wild rocket variety 89-WR019 RZ, representative seed of which has been deposited under NCIMB Accession No. 44648, 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 wild rocket variety 89-WR019 RZ and/or give rise to the expression of any one or more, or all, of the morphological and physiological characteristics of the wild rocket variety 89-WR019 RZ plant of claim 2.
