A molecular marker for resistance to stripe rust in wheat and its application in identifying resistance to stripe rust in wheat

Abstract

The application discloses a molecular marker of wheat resistance to stripe rust and application of the molecular marker in identifying wheat resistance to stripe rust. The molecular marker of wheat resistance to stripe rust is a nucleotide corresponding to the 51th nucleotide of SEQ ID No. 4 in the sequence listing on the 2B chromosome of wheat, which is C or T. Experiments prove that the molecular marker of the application is related to the resistance of wheat to stripe rust, and the resistance of wheat with homozygous nucleotide corresponding to the 51th nucleotide of SEQ ID No. 4 in the sequence listing in the genomic DNA to stripe rust is higher than that of wheat with homozygous nucleotide corresponding to the 51th nucleotide of SEQ ID No. 4 in the sequence listing in the genomic DNA. The molecular marker of the application can be used to detect the resistance of wheat to stripe rust, and further used in marker-assisted breeding. The application has important significance for cultivating wheat with enhanced resistance to stripe rust.
