The analysis of carbon isotope discrimination (Δ) in crop seeds from archaeological sites may help to assess yield during early agriculture. Wheat was among the first crops to be domesticated in the Near East. Here, a yield model based on Δ in grains from present-day crops of durum wheat (Triticum durum Def.) is developed using a wide range of genotypes, most of which were cultivated in the Eastern Mediterranean basin (Syria). A strong positive linear regression (r²
