Loci of important qualitative traits (QTL) conferring resistance to corn Fijivirus.

摘要

Loci important qualitative traits (QTL) conferring maize resistance Fijivirus. # Methods and compositions for identifying maize plants having resistance newly conferred or enhanced resistance or susceptible to Fijivirus, particularly evil viruses Rio Fourth Virus ( MRCV) and / or the rough maize dwarf (MRDV) virus. In methods using molecular genetic markers located in a region of chromosome 2 flanked by corn and MZA8381 and MZA18180 including markers it is made. The markers are shown in Tables 1 and 2, including MZA625, MZA16656, MZA15451, MZA15490, MZA2038, MZA11826 and MZA9105, and any other marker that is linked to these markers (eg, about 10 cM). Maize plants having improved recently conferred resistance or a Fijivirus generated by the methods of the invention are also a feature resistance of the invention.
