Abstract
Fusarium crown rot (FCR) is a chronic and severe disease in cereals in semi-arid regions worldwide. Previous studies showed that FCR assessment could be affected by many factors including plant height, growth rate as well as drought stress. Thus, accurate assessment, which is essential for detailed mapping of any locus conferring FCR resistance, is difficult. Targeting one of the resistance loci reported earlier, we developed a near-isogenic line-derived population consisting of 1820 F9 lines. By analysing this population, the Qcrs.cpi-4H locus was mapped to an interval of 0.09 cM covering a physical distance of about 637 kb and 13 markers co-segregating with the targeted locus were developed. Candidate genes underlying the resistance locus were identified by analysing the expression and sequence variation of genes in the targeted interval. The accurate localization and the development of co-segregating markers should facilitate the incorporation of this large-effect QTL into breeding programmes as well as the cloning of gene(s) underlying the locus.
