1. A method of creating a population of corn plants or corn seeds resistant to Downy Mildew (DM), said method comprising:
a) genotyping a first population of corn plants or corn seeds for the presence of one or more marker loci linked within about 10 centimorgans (cM) of a DM resistance allele within a DM resistance quantitative trait locus (QTL) DM_8.01;
b) selecting from said first population one or more corn plants or corn seeds comprising said one or more marker loci linked to said DM resistance allele selected from the group consisting of:
SEQ ID NO: 77, comprising an A at position 342;
SEQ ID NO: 78, comprising a C at position 422;
SEQ ID NO: 79, comprising a C at position 54; and
SEQ ID NO: 80, comprising an A at position 832; and
c) producing from said one or more corn plants or corn seeds a second population of corn plants or corn seeds comprising said DM resistance allele at said DM resistance QTL DM_8.01, wherein said second population of corn plants or corn seeds comprises at least one corn plant or corn seed having improved resistance to DM as compared to a corn plant or corn seed lacking said DM resistance allele at said DM resistance QTL DM_8.01.
