ABSTRACT Ensuring food security through sustainable practices while reducing greenhouse gas emissions are key challenges in modern agriculture. Utilising genetic variability within a crop species to identify varieties with higher root biomass carbon (C) could help address these challenges. It is thus crucial quantify and understand intra‐specific above‐ belowground performance under varying environmental conditions. The study objectives were to: (a) depth distribution different winter wheat various pedoclimatic conditions, (b) investigate the influence of variety conditions on relationship between production, (c) assess whether optimised selection can lead both greater C yield, boosting accrual. Root biomass, 1 m soil root‐to‐shoot ratios assessed 10 grown at 11 experimental sites covering European climatic gradient from Spain Norway. Median down was 1.4 ± 0.7 Mg ha −1 . primary explanatory factor site, accounting for 60% variation diversity explained 9.5%. Precipitation had significantly negative effect total especially subsoil. Significant differences also observed grain yield. difference lowest one highest across average 0.9 which an increase 45%. Pedoclimatic than variety, determined relationship's direction A site‐specific approach is, therefore, needed realise full potential increased yield offered by selection.
