摘要

Combination of alleles of three quantitative trait loci (QTLs) associated to the Resistance of maize to the virus of evil of Rio Cuarto, marker assisted selection method and a method for obtaining resistant inbred lines and hybrids of maize.Each of the loci is independently linked genetically to at least a Marker, the Marker being one or more of the following: bnlg1017 markers, bnlg2277, bnlg125, bnlg381 and bnlg180, and where the resistance is given by the presence of all alleles that confer re Resistance to these three loci.The first such Combination locus is located on chromosome 2 of maize, Bin 2.02 coordinates 80 + or - 5 and is linked to the markers and bnlg1017 bnlg2277 such Combination; The Second locus is located on chromosome 2 of maize, Bin 2.04 coordinates 198 + or - 5 and is linked to the markers and bnlg125 bnlg381; and the third of such Combination locus is located on chromosome 2 of maize, Bin 2.05 coordinates 260 + or - 5 and is linked to the bnlg180 Marker.The combination of alleles of QTL for resistance to carry out molecular marker assisted selection method for selecting a Corn Plant resistant to the virus of the Fourth Evil River through the analysis of the genetic markers linked to this Combination The Three quantitative trait loci, preferably the markers are bnlg1017, bnlg2277, bnlg125,Bnlg381, and bnlg180; and also provides a simple and Rapid Method for inbred lines and hybrids of maize resistant to the virus.
