1. A method of obtaining a corn plant with enhanced Fusarium stalk rot resistance comprising:
- a) providing a population of corn plants;
b) detecting in said plants the presence of a Fusarium stalk rot resistance allele at a polymorphic locus genetically linked to a chromosomal segment flanked by;
marker loci psk2 and gpm753d;
ormarker loci TIDP3099 and IDP4363; and
c) selecting from said population at least a first plant comprising said allele and enhanced Fusarium stalk rot resistance compared to a plant lacking said allele.

Abstract
The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding corn plants containing one or more markers that are associated with resistance to fungi. The invention further includes germplasm and the use of germplasm containing at least one marker associated with resistance to Fusarium stalk rot (FSR) infection for introgression into elite germplasm in a breeding program, thus producing novel FSR resistant germplasm.

12. A method of producing a corn plant with enhanced Fusarium stalk rot resistance comprising:
-
a) crossing a first corn plant comprising a Fusarium stalk rot resistance allele with a second corn plant of a different genotype to produce one or more progeny plants; and b) selecting a progeny plant based on the presence of said allele at a polymorphic locus genetically linked to a chromosomal segment flanked by; marker loci psk2 and gpm753d;
ormarker loci TIDP3099 and IDP4363; and wherein said allele confers enhanced resistance to Fusarium stalk rot compared to a plant lacking said allele. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
