Identifying quantitative trait loci for lodging?associated traits in the wheat doubled?haploid population Avalon × Cadenza

Lodging affects grain quality and yield in wheat (Triticum aestivum L.) is difficult to breed for because its sporadic incidence laborious protocols measure lodging traits. Thus, developing molecular markers these traits can increase selection efficiency breeding programs. The aim of this article identify quantitative trait loci (QTL) associated with stem/anchorage strength leverage (lodging traits) a doubled-haploid population UK bread Avalon × Cadenza. Field experiments were conducted the during 2012–2013 near High Mowthorpe 2013–2014 at Sutton Bonington. Phenotypic genetic analysis indicated significant variation all Stem (diameter, wall width, material strength) (plant height) highly heritable (0.64–0.95), whereas anchorage (root plate spread structural rooting depth) ear number per plant (leverage trait) less (0.21–0.33). This study identified 18 QTL chromosomes 1D, 2B, 2D, 3A, 3B, 4A, 4D, 5B, 6B. Two stem on chromosome 1D 3B explaining 49.6% total phenotypic (PVE) are estimated reduce risk shortening height by 12 cm. One root 5B 22.4% PVE could resistance.
