GENETIC LOCI ASSOCIATED WITH RESISTANCE OF CORN TO FIJIVIRUS

摘要

The invention relates to methods and compositions for identifying and/or selecting maize plants that have newly conferred resistance or enhanced resistance to, or are susceptible to, a Fijivirus, particularly Mal de Ro Cuarto Virus (MRCV) and/or Maize Rough Dwarf Virus (MRDV). The methods use molecular genetic markers to identify, select, and/or construct resistant plants or to identify and counter-select susceptible plants. Maize plants that display newly conferred resistance or enhanced resistance to a Fijivirus (or an infection or disease caused by the virus) that are generated by the methods of the invention are also a feature of the invention.
