Major QTLS conferring resistance of corn to fijivirus

A method of identifying and selecting a maize plant or germplasm that displays newly conferred resistance or enhanced resistance to a member of Serogroup 2 of Fijivirus, said method comprising:

• a. isolating nucleic acids from a maize plant or germplasm;
• b. analyzing the isolated nucleic acids for the presence of a QTL allele associated with the newly conferred resistance or enhanced resistance to a member of Serogroup 2 of Fijivirus, wherein the presence of said QTL allele is determined by detecting in the maize plant or germplasm a haplotype within a chromosomal interval flanked by and including MZA8381 and MZA18180, wherein said haplotype comprises:
• i. a “C” at MZA-625-29-A,
• ii. a “T” at MZA625-30-A, and
• iii. a “T” at MZA16656-8-A, and
• c. selecting said maize plant or germplasm if said QTL allele is detected.
