The invention relates to a Brassica plant in particular a Brassica oleracea plant comprising a genetic determinant, which when homozygously present confers high resistance against Thrips tabaci, and which is as found in plants grown from seeds of which a representative sample is deposited with the NCIMB under NCIMB accession number 41760. Preferably, the plant is homozygous for the genetic determinant and resistant against Thrips tabaci. The genetic determinant in the seeds of NCIMB deposit 41760 is located on chromosome 2 and linked to marker BO00200 (SEQ ID NO: 1) and/or marker BO00277 (SEQ ID NO: 2) and/or BO00602 (SEQ ID NO: 5).
