Abstract

The present invention concerns a canola germplasm comprising at least 45% crude protein and not more than 18% acid detergent fiber content on an oil-free, dry matter basis. Certain embodiments further comprise one or more traits selected from the group consisting of reduced polyphenolic content and increased phosphorous content. In particular embodiments, the invention concerns canola plants comprising such germplasm and plant commodity products (e.g., seeds) produced therefrom. Canola plants comprising a germplasm of the invention may exhibit favorable seed composition characteristics that make them particularly valuable as a source for canola meal, and for methods of introducing at least one trait selected from the group consisting of high protein content, low fiber content, reduced polyphenolic content and increased phosphorous content into a canola variety in a seed coat color-independent manner.

First claim

What is claimed is:

1. A dark canola seed characterized by a seed oil comprising at least 68% oleic acid (C18:1) and less than 3% linolenic acid (C18:3), wherein the dark canola seed is selected from the group consisting of CL065620 (ATCC No. PTA-11697), CL044864 (ATCC No. PTA-11696), CL121460H (ATCC No. PTA-11698), CL166102H (ATCC No. PTA-12570), and CL121466H (ATCC No. PTA-11699).

2. The dark canola seed of claim 1 , comprising at least 45% crude protein.

3. The dark canola seed of claim 1 , comprising not more than 18% acid detergent fiber on an oil-free, dry mass basis.

4. The dark canola seed of claim 1 , comprising a phosphorous content of at least 1.3% on an oil-free, dry mass basis.

5. A canola plant producing the dark canola seed of claim 1 .

6. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having, on average, at least about 45% crude protein content.

7. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having, on average, not more than about 18% acid detergent fiber as determined on an oil-free, dry mass basis.

8. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having, on average, less than 2% erucic acid.

9. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having a lignin and polyphenolic content of less than 6.4% on an oil-free, dry matter basis.

10. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having an acid detergent fiber content of below 11% on an oil-free, dry matter basis.

11. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds comprising at least 43% oil.

12. The canola plant of claim 5 , wherein the canola plant was produced without genetic engineering and without mutagenesis.

13. The canola plant of claim 5 , wherein the canola plant produces dark canola seeds having a phosphorous content of more than 1.3% on an oil-free, dry matter basis.

14. A progeny canola plant grown from the seed of claim 1 .

15. A progeny canola plant of claim 14 , wherein the progeny canola plant produces dark canola seeds that are characterized by a seed oil comprising, on average, at least 68% oleic acid (C18:1) and less than 3% linolenic acid (C18:3).

16. The progeny canola plant of claim 14 , wherein the progeny canola plant produces dark canola seeds having at least about 45% crude protein content.

17. The progeny canola plant of claim 14 , wherein the progeny canola plant produces dark canola seeds having not more than about 18% ADF as determined on an oil-free, dry matter basis.

18. A dark canola meal produced from one or more of the seeds of claim 1 .

19. The dark canola meal of claim 18 , wherein the meal has a mean true metabolizable energy of at least 2400 kcal/kg.

20. The dark canola meal of claim 18 , wherein the meal comprises an amino acid digestibility at least about 90% of that of soybean meal.

21. The dark canola meal of claim 18 , wherein the meal comprises a digestible energy content or a metabolizable energy content at least about 80% of that of soybean meal.
