Trait Locus

Chromosome 2A of wild emmer wheat (Triticum turgidum var. dicoccoides) genotype Israel A increases Fusarium head blight (FHB) severity when present in durum wheat (T. turgidum var. durum) cv. Langdon (LDN). The goal of this study was to identify regions of Israel A chromosome 2A associated with this difference in resistance. A recombinant inbred chromosome line population (RICL) from a cross between LDN and the LDN-Israel A chromosome 2A substitution line [LDN(DIC-2A)] was employed for analysis. Three greenhouse FHB evaluations were completed on the RICL to obtain phenotypic data on variation for FHB resistance, and a simple sequence repeat (SSR)-based molecular map of chromosome 2A was developed. Quantitative trait locus (QTL) mapping identified a region on the long arm of chromosome 2A that was associated with FHB resistance in each independent FHB evaluation. Depending on the evaluation, the single best SSR marker in this region accounted for between 21 and 26% of the variation for FHB resistance, with the Israel A marker alleles associated with increased FHB susceptibility. The single best markers from each evaluation reside within an interval of approximately 22 cM. This study identifies one or more new QTL on chromosome 2A in tetraploid wheat that can contribute to significant variation in FHB resistance.
