摘要: Wheat yellow mosaic disease, which is caused by wheat yellow mosaic bymovirus (WYMV) and transmitted by soil-borne fungus, results in severe damage on wheat (Triticum aestivum L.) production in China. For development of resistant cultivars to reduce wheat yield losses due to wheat yellow mosaic disease, resistance test and genetic analysis indicated that a single dominant gene in wheat cultivar Yangfu 9311 contributed to the resistance. Bulk segregant analysis was used to identify microsatellite markers linked to the resistance gene in an F-2 population derived from the cross Yangfu 9311 (resistant) x Yangmai 10 (susceptible). Microsatellite markers Xwmc41, Xwmc181, Xpsp3039, and Xgwm349 were co-dominantly or dominantly linked with the gene responsible for WYMV resistance at a distance of 8.1-11.6 cM. Based on the wheat microsatellite consensus map and the results from amplification of the cultivar Chinese Spring nulli-tetrasomic stocks, the resistance gene to wheat yellow mosaic disease derived from Yangfu 9311, temporarily named as YmYF, was thus mapped on the long arm of chromosome 2D (2DL).
