Application of Aegilops tauschii–Triticum aestivum recombinant inbred lines for grain protein content quantitative trait loci detection and wheat improvement

Grain protein content (GPC) is an important nutritional quality trait of wheat. Aegilops tauschii Coss. is a progenitor of common wheat and has been shown to have high GPC. The objective of this study was to identify quantitative trait loci (QTL) for GPC using A. tauschii–Triticum aestivum L. recombinant lines. An advanced BC 2 F 6 population (112 lines) containing A. tauschii segments was developed using synthetic octaploid wheat (hexaploid...
