Brassica plants resistant to disease

摘要

The present invention relates to novel Brassica oleracea plants resistant to Albugo candida and the seeds of said plants. The invention also relates to methods of making such plants and for producing seeds thereof. The invention further relates to molecular markers and use thereof in marker assisted breeding and for identifying Albugo candida resistance trait in Brassica oleracea plants.

主权项

1. Cultivated Brassica oleracea plant resistant to Albugo candida, comprising a resistance locus, such resistance locus being present in Brassica oleracea L var gemmifera UK 925, seed of which is deposited under Deposit Number NCIMB 41654, and wherein said resistance locus is a monogenic and semi-dominant resistance locus located on chromosome 2, and wherein the Albugo candida resistance locus is genetically linked to at least one marker locus, which co-segregates with Albugo candida resistance trait and comprises a marker that can be identified in a PCR reaction by amplification of a DNA fragment with a pair of PCR oligonucleotide primers represented by a forward primer of SEQ ID NO: 1 and a reverse primer of SEQ ID NO: 2.
