QTLS FOR FUSARIUM RESISTANCE IN CUCUMBER

摘要

The present invention relates to a cucumber plant which carries a QTL1 in its genome that leads to resistance to Fusarium oxysporum f. sp. radicis-cucumerinum. Said QTL1 is located on chromosome 3 between marker sequences SEQ ID No. 1 and SEQ ID No. 2 and can be identified by any of the markers having SEQ ID No. 3, and/or SEQ ID No. 4. QTL1 is as comprised in the genome of a cucumber plant representative seed of which was deposited with the NCIMB under deposit numbers NCIMB 42438 and NCIMB 42439. Optionally, in addition to the QTL1 also a QTL2 is present, which is located on chromosome 5 between marker sequences SEQ ID No. 5 and SEQ ID No. 6 and which can be identified by any of the markers on chromosome 5 having SEQ ID No. 7, SEQ ID No. 8, SEQ ID No. 9, and/or SEQ ID No. 10, or any combination of these SEQ ID Nos. QTL2 is as comprised in the genome of a cucumber plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42439. A cucumber plant of the invention can comprise both QTLs, each either in homozygous or heterozygous form. The invention further relates to progeny of the plant, propagation material for the plant and to markers for identifying the QTLs and their use.
