## Abstract

Canola plants with high oleic acid and low linolenic acid content are disclosed. In addition, the canola plants of the invention are resistant to imidazolinone herbicides and are resistant to blackleg. The canola plants of the invention also have low total glucosinolate content. There is also provided a method for controlling weeds in a field of canola plants wherein the canola plants are herbicide resistant.

## Claims

### Claim 1

A canola seed comprising imidazolinone resistance, and further comprising oleic acid content in the total seed oil of greater than 70.0% by weight, wherein the seed is obtained from a canola cultivar that is a progeny of crossing canola cultivars 45A71, Nex 705 (ATCC Deposit No. PTA-2087), and Nex 715.

### Claim 2 (depends on 1)

The canola seed of claim 1, wherein the oleic acid content is between 70.1% and 72.0% by weight.

### Claim 3 (depends on 1)

The canola seed of claim 1, wherein the oleic acid content is between 72.1% and 74.0% by weight.

### Claim 4 (depends on 1)

The canola seed of claim 1, wherein the oleic acid content is between 74.1% and 76.0% by weight.

### Claim 5 (depends on 1)

The canola seed of claim 1, further comprising less than 3.0% by weight linolenic acid in the total seed oil.

### Claim 6 (depends on 5)

The canola seed of claim 5, wherein the linolenic acid content is between 2.0% and 2.99% by weight.

### Claim 7 (depends on 5)

The canola seed of claim 5, wherein the linolenic acid content is between 1.0% and 1.99% by weight.

### Claim 8 (depends on 5)

The canola seed of claim 5, wherein the linolenic acid content is between 0.5% and 0.99% by weight.

### Claim 9 (depends on 1)

A canola plant produced from the seed of claim 1, further comprising blackleg (Leptosphaeria maculans) resistance.

### Claim 10 (depends on 5)

A canola plant produced from the seed of claim 5, further comprising blackleg (Leptosphaeria maculans) resistance.

### Claim 11 (depends on 1)

The canola seed of claim 1, further comprising total glucosinolate content of less than 12.0 μm/g of seed.

### Claim 12 (depends on 11)

The canola seed of claim 11, the seed comprising total glucosinolate content of between 10.0 μm/g and 11.99 μm/g of seed.

### Claim 13 (depends on 11)

The canola seed of claim 11, the seed comprising total glucosinolate content of between 8.0 μm/g and 9.99 μm/g of seed.

### Claim 14 (depends on 11)

The canola seed of claim 11, the seed comprising total glucosinolate content of between 7.0 μm/g and 7.99 μm/g of seed.

### Claim 15 (depends on 1)

A canola plant produced from the seed of claim 1.

### Claim 16 (depends on 1)

The canola seed of claim 1, wherein the seed is obtained from a hybrid canola cultivar obtained by a method comprising:
crossing canola cultivar 45A71 with canola cultivar Nex 705 (ATCC Deposit No. PTA-2087) to produce an F1 plant;
backcrossing the F1 plant with canola cultivar Nex 705 to obtain an F2 plant; and
crossing the F2 plant with canola cultivar Nex 715, thereby producing the hybrid canola cultivar.

### Claim 17 (depends on 16)

The canola seed of claim 16, wherein the seed is obtained from the canola cultivar designated NQC02CNX13 (ATCC Deposit No. PTA-6643).

### Claim 18 (depends on 16)

A canola plant produced from the seed of claim 16.

### Claim 19 (depends on 17)

A canola plant produced from the seed of claim 17.

### Claim 20 (depends on 1)

The canola seed of claim 1, wherein the seed is obtained from a single gene conversion of a canola cultivar selected from the group consisting of the cultivar designated NQC02CNX12 (ATCC Deposit No. PTA-6011), the cultivar designated NQC02CNX13 (ATCC Deposit No. PTA-6643), the cultivar designated NQC02CNX25 (ATCC Deposit No. PTA-6012), and the cultivar designated NQC02CNX21 (ATCC Deposit No. PTA-6644).

### Claim 21 (depends on 15)

A method of controlling at least one weed in a field, wherein the field contains at least one canola plant of claim 15, the method comprising applying an imidazolinone herbicide to at least a portion of the field that contains the canola plant.

### Claim 22 (depends on 21)

The method according to claim 21, wherein the canola plant further comprises glyphosate resistance, the method further comprising applying a glyphosate herbicide to at least a portion of the field.

### Claim 23 (depends on 21)

The method according to claim 21, wherein the canola plant further comprises glufosinate resistance, the method further comprising applying a glufosinate herbicide to at least a portion of the field.

### Claim 24 (depends on 21)

The method according to claim 21, wherein the canola plant further comprises 2, 4-D resistance, the method further comprising applying a 2, 4-D herbicide to at least a portion of the field.
