Plant height (PH) plays a pivotal role in plant morphological architecture and is associated with yield potential in wheat. For the quantitative trait locus (QTL) analysis, a recombinant inbred line population was developed between varieties differing significantly in PH. Two major QTL were identified on chromosomes 4B ( QPh.sicau-4B ) and 6D ( QPh.sicau-6D ) in multiple environments, which were then validated in two different backgrounds by using closely linked markers.  QPh.sicau-4B  explained 10.1–21.3% of the phenotypic variance, and the location corresponded to the dwarfing gene  Rht-B1 .  QPh.sicau-6D  might be a novel QTL for PH, explaining 6.6–13.6% of the phenotypic variance and affecting spike length, thousand-kernel weight, and spikelet compactness. Three candidate genes associated with plant growth and development were identified in the physical interval of  QPh.sicau-6D . Collectively, we identified a novel stable and major PH QTL,  QPh.sicau-6D , which could aid in the development of closely linked markers for marker-assisted breeding and cloning genes underlying this QTL.
