Fructans (fructo-oligosaccharides) are prebiotics that are thought to selectively promote the growth of colonic biWdobacteria, thereby improving human gut health. Fructans are present in the grain of wheat, a staple food crop. In the research reported here, we aimed to detect and map loci aVecting grain fructan concentration in wheat using a doubled-haploid population derived from a cross between a high-fructan breeding line, Berkut, and a lowfructan cultivar, KrichauV. Fructan concentration was measured in grain samples grown at two locations in Australia and one in Kazakhstan. Fructan concentration varied widely within the population, ranging from 0.6 to 2.6% of grain dry weight, and was quite repeatable, with broadsense heritability estimated as 0.71. With a linkage map of 528 molecular markers, quantitative trait loci (QTLs) were...
