Key Points

To assess strategies for decreasing wheat production's reliance on nitrogen fertilizer by expanding beyond modern cultivar genetics.
Evaluation of existing genetic diversity within modern wheat cultivars.
Investigation into wider germplasm pools, including traditional landraces and ancestral plant lineages.
Modern cultivars possess existing genetic variation, but it is insufficient alone for substantial efficiency gains.
Significant reductions in nitrogen fertilizer reliance necessitate exploiting broader germplasm resources, specifically landraces and ancestral germplasm.
