Abstract

The invention discloses a wheat stripe rust resistance QTL molecular marker IWB12253 and an application thereof. The wheat stripe rust resistance QTL molecular marker IWB12253 is nucleotide shown at a51st site of a sequence 4 in a sequence table in a wheat genome, the wheat disease resistance molecular marker is T or C, experiments find that the stripe rust resistance of wheat with T at an SNP site IWB12253 is remarkably higher than that of wheat with C at the SNP site IWB12253, and the IWB12253 is related to the stripe rust of the wheat and can be used for detecting the stripe rust resistance of the wheat and breeding stripe rust resistant molecules.

Description

technical field [0001] The invention relates to the QTL molecular marker IWB12253 for resistance to stripe rust in wheat and its application in the field of biological agriculture. Background technique [0002] Wheat stripe rust is a fungal disease that occurs worldwide and is caused by wheat stripe rust (Puccinia striiformis Westend.f.sp.tritici). Stripe rust mainly damages wheat leaves, affects photosynthetic rent, and leads to yield reduction. Breeding and planting disease-resistant varieties is the most cost-effective and environmentally friendly method to control stripe rust. Genetic research on disease resistance is an important basis for disease resistance breeding. Because the physiological races of wheat stripe rust are prone to mutations, which can lead to the loss of resistance of existing disease resistance genes, the discovery of new disease resistance genes and the development of their linkage markers are of great significance for enriching stripe rust resist...
