Genomic selection (GS) has emerged as a promising approach in plant breeding, especially for complex traits like grain yield that are influenced by many small-effect quantitative trait loci (QTLs). Choosing the optimal prediction model is important for GS. Using 4 years of field data from a diverse panel of spring wheat lines, the present study assessed the ability of seven statistical models to predict grain yield (YLD), tota...

Key message Two dwarf bunt resistance QTLs were mapped to chromosome 6D, and KASP markers associated with the loci were developed and validated in a panel of regionally adapted winter wheats. UI Silver is an invaluable adapted resistant cultivar possessing the two identified QTL potentially associated with genes Bt9 and Bt10 and will be useful in future cultivar development to improve dwarf bunt resistance. Abstract Dwarf bunt...

Key message Four genomic regions on chromosomes 4A, 6A, 7B, and 7D were discovered, each with multiple tightly linked QTL (QTL clusters) associated with two to three yield components. The 7D QTL cluster was associated with grain yield, fertile spikelet number per spike, thousand kernel weight, and heading date. It was located in the flanking region of FT-D1, a homolog gene of Arabidopsis FLOWERING LOCUS T, a major gene that re...
