METHODS FOR IDENTIFYING A FIRST CORN OR GERM PLASM PLANT THAT HAS NEWLY CONFERRED RESISTANCE OR INCREASED RESISTANCE OR SUSCEPTIBILITY TO A FIJIVIRUS; PLANT OF CORN INTRODUCED OR GERMOPLASM INTRODUCED; METHOD OF PRODUCTION OF A CORN PLANT PRESENTING NEWLY CONFERTED RESISTANCE OR INCREASED RESISTANCE TO A FIJIVIRUS; SELECTION METHOD OF AT LEAST ONE CORN PLANT THROUGH SELECTION ASSISTED BY A QUANTITATIVE TRACE PLUS ASSOCIATED WITH RECOMMENDED RESISTANCE OR INCREASED RESISTANCE TO A FUJIVIRUS.

摘要

The invention relates to methods and compositions for identifying maize plants that have newly conferred resistance or enhanced resistance to, or are susceptible to, a Fijivirus, particularly Mal de Río 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 identify and counter-select susceptible plants. Maize plants that display newly conferred resistance or enhanced resistance to a Fijivirus that are generated by the methods of the invention are also a feature of the invention.
