Abstract

The present invention provides a polynucleotide which enables the modulation of the seed vigor, and in particular enhances the seed vigor, and more particularly enables the modification of the speed of germination. A plant seed comprising the said polynucleotide is also provided. A method of producing the plant seed, method for improving the germination and vigor of plant seed, transgenic plant and the use of the polynucleotide of the invention for producing plants growing seeds with improved germination and vigor characteristics are also provided. The invention particularly concerns Brassica, more particularly Brassica oleracea.

First claim

The invention claimed is:

1. A cultivated hybrid Brassica plant or plant part which contains within its genome an introgression comprising the nucleotide sequence of SEQ ID NO: 16 at the Speed of Germination (SOG1) QTL from Brassica oleracea line SL101, representative seed of line SL101 having been deposited at NCIMB under deposit number NCIMB 41951, and which exhibits an increase in speed of seed germination as compared to a Brassica plant or plant part that does not comprise the introgression from Brassica oleracea line SL101.

2. The cultivated Brassica plant or plant part according to claim 1 that is selected from the group consisting of a Brassica oleracea, Brassica napus , and Brassica rapa plant or plant part.

3. The cultivated Brassica plant or plant part according to claim 1 that is a Brassica oleracea plant or plant part.

4. A cultivated hybrid Brassica plant or plant part which contains within its genome an introgression comprising the nucleotide sequence of SEQ ID NO: 16 at the Speed of Germination (SOG1) QTL from Brassica oleracea line SL101, representative seed of line SL101 having been deposited at NCIMB under deposit number NCIMB 41951, and which exhibits an increase in percentage of seed germination as compared to a Brassica plant or plant part that does not comprise the introgression from Brassica oleracea line SL101.

5. The cultivated Brassica plant or plant part according to claim 4 that is selected from the group consisting of Brassica oleracea, Brassica napus , and Brassica rapa.

6. The cultivated Brassica plant or plant part according to claim 4 that is a Brassica oleracea plant or plant part.
