METHOD OF IDENTIFYING A CORN OR GERM PLASM PLANT THAT HAS NEWLY CONFERED RESISTANCE OR INCREASED RESISTANCE TO A FIJIVIRUS SOROGRUP 2 MEMBER, OR SUSCEPTIBILITY TO A FIJIVIRUS SOROGRUPT MEANS A PRODUCT CONCERNED OR INCREASED RESISTANCE TO A FIJIVIRUS SERGROUP 2 MEMBER AND METHOD OF SELECTION AT LEAST ONE CORN PLANT THROUGH SELECTION ASSISTED BY A QUANTITATIVE TRACE LOCATION ASSOCIATED WITH THE RECENTLY RESISTANCE MEMBER FIJIVIRUS SEROGROUP 2

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.
