Abstract:

Wheat is one of the most important food crops in China and worldwide. Wheat production is facing the stresses of different diseases including Fusarium head blight (FHB) which is more and more serious recently and leading to highly concerns. Unremitting efforts have been made on Fusarium head blight resistance breeding and comprehensive control technology development. Rapid progress has been achieved on discovering of resistant genetic resources, mapping of resistant QTL/genes, resistant QTL/genes cloning, gene functional research and molecular breeding. In this review, we summarize the current status of the research against FHB in wheat and discuss the issues of FHB resistance investigation to date. We also suggest emphasizing on gene cloning, developing more powerful functional markers, using haplotype-assisted selection (HAS) and marker-set-assisted selection (MSAS) for further deep FHB resistance study and breeding.

Key words: wheat, Fusarium head blight (FHB), QTL/gene, molecular breeding
