Abstract
The present disclosure provides Brassica oleracea plants having curds or heads exhibiting increased resistance to downy mildew. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea MYCOCLP. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.
Claims9
An introgression fragment comprising a first recombinant chromosomal segment on chromosome 3 from Brassica oleracea MYCOCLP comprising marker M19 (SEQ ID NO:2) and marker M20 (SEQ ID NO:3) and a second recombinant chromosomal segment on chromosome 3 from Brassica oleracea MYCOCLP comprising marker M31 (SEQ ID NO:4) and marker M44 (SEQ ID NO:16), wherein said first and second recombinant chromosomal segments on chromosome 3 are both flanked in the introgression fragment by genomic DNA from a cultivated Brassica oleracea variety, wherein said fragment confers resistance to downy mildew, and wherein a sample of seed comprising said first chromosomal segment and said second chromosomal segment was deposited under ATCC Accession Number PTA-124338.
