Final Report: CSP00018 - Wheat germplasm with improved yield performance under drought for Australian breeding programs

Plain text source: 
The project has identified genomic regions, developed germplasm (alternative dwarfing genes, leaf-rolling, greater leaf area) and established screening methodologies (longer coleoptiles, leaf area, transpiration efficiency) targeted to improving water-use efficiency and yield under drought... The project has confirmed and/or extended genetic variation for traits with potential for use in breeding for improved performance under drought, identified the nature of inheritance for some of these traits and underlying genetic control through quantitative trait loci (QTL), and released germplasm containing genes for traits not present within Australian breeding programs... The F1 progeny were assessed in seedling trays and produced leaf-one widths ranging between 2.8 and 7.6 millimetres (mm)...
