Abstract

The invention relates to improved Brassica species, including Brassica juncea, improved oil and meal from Brassica juncea, methods for generation of such improved Brassica species, and methods for selection of Brassica lines. Further embodiments relate to seeds of Brassica juncea comprising an endogenous oil having increased oleic acid content and decreased linolenic acid content relative to presently existing commercial cultivars of Brassica juncea, seeds of Brassica juncea having traits for increased oleic acid content and decreased linolenic acid content in seed oil stably incorporated therein, and one or more generations of progeny plants produced from said seeds.

Claims

1. An endogenous oil extracted from the seeds of Brassica juncea plant according to claim 1, said seeds having a fatty acid content comprising at least 70.0% oleic acid and less than 5.0% linolenic acid by weight.

2. The oil of claim 1 having a fatty acid content comprising 70.0% to 85.0% oleic acid.

3. The oil of claim 1 having an endogenous fatty acid content comprising less than 3.0% linolenic acid by weight.

4. The oil of claim 1 having an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight.

5. The oil of claim 1 having an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight and less than 3.0% linolenic acid by weight.

6. A seed oil produced in seeds of a crop of non-transgenic Brassica juncea plants, said seed oil having a fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.

7. The seed oil of claim 6 having an endogenous fatty acid content comprising less than 3.0% linolenic acid by weight.

8. The seed oil of claim 6 having an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight.

9. The seed oil of claim 6 having an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight and less than 3.0% linolenic acid by weight.

10. A crop of Brassica juncea producing seeds having an endogenous oil content which averages, across the crop, at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.

11. The crop of claim 10, wherein the seeds have an endogenous fatty acid content comprising less than 3.0% linolenic acid by weight.

12. The crop of claim 10, wherein the seeds have an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight.

13. The crop of claim 10, wherein the seeds have an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight and less than 3.0% linolenic acid by weight.

14. One or more generations of progeny crops resulting from at least one of the seeds of the crop of claim 10.

15. The progeny crops of claim 14, wherein the crops produce seeds have an endogenous oil content which averages, across the crop, at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.

16. The crop of claim 14, wherein the seeds have an endogenous fatty acid content comprising less than 3.0% linolenic acid by weight.

17. The crop of claim 14, wherein the seeds have an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight.

18. The crop of claim 14, wherein the seeds have an endogenous fatty acid content comprising 70.0% to 85.0% oleic acid by weight and less than 3.0% linolenic acid by weight.
