Methods and compositions for producing corn plants with resistance to late wilt

A method of creating a population of Late Wilt (LW) resistant corn plants or corn seeds, said method comprising:

• a) obtaining a first progeny population of corn plants or corn seeds;
• b) genotyping said first progeny population of corn seeds or plants grown therefrom at one or more marker loci linked to, and within 10 centimorgans (cM) of LW resistance quantitative trait locus (QTL) LW_3.02;
• c) selecting from said first progeny population one or more corn plants or corn seeds comprising said one or more marker loci linked to said LW resistance QTL LW_3.02 linked to an LW resistance allele selected from the group consisting of:
• SEQ ID NO:
• 44, SEQ ID NO:
• 258, SEQ ID NO:
• 259, SEQ ID NO:
• 260, SEQ ID NO:
• 261, SEQ ID NO:
• 262, SEQ ID NO:
• 263, and SEQ ID NO:
• 264;
• and
• d) crossing said selected one or more corn plants or corn plants grown from said seeds with a second corn plant to produce a second progeny corn seed or plant grown therefrom comprising said one or more of said marker loci linked to said LW resistance allele at said LW resistance QTL LW_3.02.

A method of creating a population of Late Wilt (LW) resistant corn plants or corn seeds, said method comprising:

• a) genotyping a first population of corn plants or corn seeds at one or more marker loci linked to, and within 10 centimorgans (cM) of any one of marker loci linked to an LW resistance allele selected from the group consisting of SEQ ID NO:
• 44, SEQ ID NO:
• 258, SEQ ID NO:
• 259, SEQ ID NO:
• 260, SEQ ID NO:
• 261, SEQ ID NO:
• 262, SEQ ID NO:
• 263, and SEQ ID NO:
• 264, wherein said marker loci is associated with an LW resistance quantitative trait locus (QTL) LW_3.02;
• b) selecting from said first population one or more progeny corn plants or corn seeds comprising said one or more marker loci linked to said LW resistance allele;
• and
• c) producing from said selected one or more progeny corn plants or corn seeds via crossing a second progeny population of corn plants grown therefrom or corn seeds comprising said one or more marker loci linked to said LW resistance allele.
