主　　题：Fusarium head blight marker-assisted selection Fhb1 Fhb2 resistance breeding wheat 

摘      要：Fusarium head blight(FHB)is one of the most detrimental wheat diseases which greatly decreases the yield and grain quality,especially in the middle and lower reaches of the Yangtze River of ***1 and Fhb2 are two major resistance loci against Fusarium *** 15(YM15)is one of the most popular varieties in the middle and lower reaches of the Yangtze River,and it has good weak gluten characters but poor resistance to *** we used Fhb1 and Fhb2 to improve the FHB resistance of YM15 by a molecular marker-assisted selection(MAS)backcrossing *** selection of agronomic traits was performed for each *** successfully selected seven introgressed lines which carry homozygous Fhb1 and Fhb2 with significantly higher FHB resistance than the recurrent parent *** of the introgressed lines had agronomic and quality characters that were similar to *** study demonstrates that the pyramiding of Fhb1 and Fhb2 could significantly improve the FHB resistance in wheat using the MAS approach.
