1. A method of creating a population of Northern Leaf Blight (NLB) resistant corn plants, corn seeds, or corn cells, said method comprising:

  • a) crossing a first NLB resistant corn plant comprising NLB resistance quantitative trait locus (QTL) NLB_4.01 with a second corn plant to generate a first population of corn plants, corn seeds, or corn cells;

    b) genotyping said first population of corn plants, corn seeds, or corn cells at one or more marker loci linked to, and within 10 centimorgans (cM) of, said NLB resistance QTL NLB_4.01; and

    c) selecting from said first population one or more corn plants, corn seeds, or corn cells having resistance to NLB comprising said one or more of said marker loci linked to said NLB resistance QTL NLB_4.01 linked to an NLB resistance allele selected from the group consisting of;
