This paper improves genomic prediction accuracy in winter wheat by integrating genotype-by-environment interactions and environmental covariates across multiple environments.

The paper analyzes historic wheat trials to show how vrn1 and Ppd1 alleles affect yield through environmental interactions, finding that vrn1 effects are more variable than Ppd1 effects.

A GWAS of 337 US soft winter wheat genotypes identified 12 marker-trait associations for resistance to Zymoseptoria tritici, including both known and novel resistance genes.

This study identifies genome-wide markers for metribuzin tolerance in southern soft red winter wheat using genomic prediction and GWAS.

This study demonstrates that genomic selection can predict glycosidic nitrile content in winter barley during the same growing season, enabling earlier breeding decisions.

This study identifies TaWUS2D as a gene that increases grain number per spikelet by promoting fertile ovaries in wheat through genetic and genomic analyses.

The paper develops a high-density SNP genotyping array for wheat using whole genome skim sequencing and a novel optimization approach, showing improved performance in GWAS and CNV analysis.

The paper sequences 4.3 million promoter mutations and 4.7 million coding mutations in wheat to understand gene function and improve agronomic traits.

The paper estimates the yield effects of awns in wheat under different environmental conditions over 12 years in the Southeast US, finding awns improve yield in heat-stressed environments.

The paper develops a wheat haplotype graph database for efficient genotype storage and imputation, showing improved accuracy over existing methods.

The paper identifies major and novel QTL for plant height and heading date in wheat using a biparental population, showing that genetic variation is dominated by known variants and moderate-effect QTL.

This study identifies genetic variation affecting tiller number and rate in barley, finding correlations with agronomic traits and QTL overlapping with days to heading and spike row-type.
