Modulation of seed vigor
The present invention provides a polynucleotide which enables the modulation of the seed vigour, and in particular enhances the seed vigour, 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 vigour of plant seed, transgenic plant and the use of the polynucleotide of the invention for producing plants growing seeds with improved germination and vigour characteristics are also provided. The invention particularly concerns Brassica , more particularly Brassica oleracea.
1. A cultivated hybrid Brassica plant or plant part which contains within its genome an introgression comprising the nucleotide sequence of SEQ ID NO: 10 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.
