However, studies on the shift in structure and biodiversity of soil seedbanks in herbicide‐resistant crop systems are limited, and a functional trait perspective of the soil seedbank is often overlooked.RESULTSA 6 years experiment was conducted to investigate the roles of region, crop system, and weed management strategy on species richness, functional trait diversity, and composition of the weed seedbank. Species richness was different across the interaction of region and crop system, while functional trait diversity only showed difference across regions. Species and functional trait compositions were affected by the interaction of region and crop system. Specifically, the compositional difference among crop systems was mainly determined by the significant heterogeneity of group dispersion.CONCLUSIONGrowers and practitioners should consider weed functional traits in developing lasting agricultural management strategies. Long‐term weed research should draw attention to the impact of transgenic crop systems and specific management tactics on weed dispersal, functional composition, and resistance evolution of weed species in such agroecosystems. © 2023 The Authors.
