Genetic loci associated with resistance of corn to fijivirus

A method of identifying and/or selecting a maize plant that displays enhanced resistance to MRCV infection, the method comprising detecting in the germplasm of the maize plant a haplotype comprising alleles at one or more marker loci, wherein:

• a. the one or more marker loci are located within a chromosomal interval comprising and flanked by:
• i. PHM1718 and PHM8008 or
• ii. PHM669 and PHM8008;
• and
• b. the haplotype is associated with enhanced resistance to MRCV infection.

A method of identifying and/or selecting a maize plant that displays enhanced resistance to MRCV infection, the method comprising:

• a. obtaining a first maize plant that comprises within its genome
• i. a haplotype comprising a “G” at position 324, a “C” at position 345, a “G” at position 504, and an “A” at position 565, relative to SEQ ID NO:44;
• ii. a haplotype comprising an “A” at position 85, a “C” at position 344, and an “A” at position 355 relative to SEQ ID NO:42;
• iii. a haplotype comprising a “G” at position 58, an insertion at position 61, a “C” at position 70, a “C” at position 85, a “T” at position 90, a “G” at position 194, and an “A” at position 287, relative to SEQ ID NO:43;
• or
• iv. any combination of i.-iii.
• b. crossing said first maize plant to a second maize plant;
• c. evaluating progeny plants for any of i-iv in (a);
• and
• d. identifying and/or selecting progeny plants that possess any of i-iv in (a).
