Abstract excerpt

KEY MESSAGE: Stem structural investment enhances grain size and yield under drought, challenging the traditional view of vegetative-reproductive trade-offs. Antagonistic pleiotropy at the SSt1 locus reveals a genetic constraint between stem diameter and solidness. Incorporating genotype-by-environment into genomic selection models improves prediction accuracy by 46.5%. Terminal drought is the primary...
