Abstract Optimal root system architecture (RSA) is critical for efficient resource capture in soils, hence being an interest crop breeding. Seminal angle (SRA) at the seedling stage durum wheat has been suggested to be a good indicator of RSA. However, research on correlating such lab-based phenotyping RSA later phases plant growth limited, resulting importance trait variation seen seedlings often overstated. To explore role SRA modifying growth, we assessed 11 genotypes contrasting (wide and narrow), grown rhizobox designed systems plants during late-tillering. Above-ground traits dry mass different soil depths across entire volume were measured manually, while architectural extracted using image analysis summarised by multiple factor describe When comparing wide narrow genotypes, no differences detected above-ground total mass. observed allocation depths. The showed distinct RSAs, particularly upper (0 ‒ 30 cm). exhibited ‘spread-out’ with dense thin roots, whereas had compact fewer but thicker roots. Our study demonstrated clear difference between highlighting association direction distribution stages.
