Abstract Background and aims Understanding the relationship of root traits and crop performance under varying environmental conditions facilitates the exploitation of root characteristics in breeding and variety testing to maintain crop yields under climate change. Therefore, we (1) evaluated differences in root length and surface area between ten winter wheat varieties grown at 11 sites in Europe covering a large pedoclimatic gradient, (2) quantified differences in root response to soil, climate and management conditions between varieties, and (3) evaluated variety-specific relationships of grain yield and root length and surface area under diverse environmental conditions. Methods At each site, we sampled the roots to 1 m soil depth after harvest and determined various root traits by scanning and image analysis. The impacts of soil, climate and management on roots and yield of the ten varieties were analysed by means of multivariate mixed models. Key results Root length averaged 1.4 m root piece−1, 5007 m root m−2 soil, and 5300 m root m−2 soil and root surface area 0.039 m2 root piece−1, 40 m2 root m−2 soil, and 43 m2 root m−2 soil in 0.00–0.15 m, 0.15–0.50 m, 0.50–1.00 m soil depth, respectively. The variation in both traits was 10 times higher between sites than varieties, the latter ranging by a factor of 2 within sites. Irrespective of variety, temperature was a major driver of subsoil root traits, suggesting that warmer climates promoted root growth in deeper soil layers. Other soil and climate variables affected root length and/or root surface area of individual varieties, highlighting different degrees of root plasticity. The varieties displayed distinctly different relationships between yield and root traits under varying pedoclimatic conditions, highlighting genetic differences in yield response to environmentally driven root plasticity. Conclusions These findings suggest that breeding efforts should target flexible root–yield relationships in the subsoil to maintain crop performance under climate change.

Abstract
Bulb mites (Rhizoglyphus spp.) can predispose onions to various fungal diseases. At the same time, onions infected with Fusarium spp. have been shown to attract bulb mites. In addition, bulb mite establishment has been shown to be more successful and population growth faster on Fusarium spp. infected onions. Understanding the interactions between bulb mites and Fusarium spp. is essential for developing effective Integrated Pest Management (IPM) strategies targeting both Fusarium spp. and bulb mites. However, there is no information on the interactive effects of bulb mites and F. oxysporum f. sp. cepae on onions in Norway. Likewise, there is no prior knowledge of which bulb mite species damage onion in Norway. In the ongoing project, we study which bulb mite species exist in Norway, whether basal rot development is affected by the presence of bulb mite (R. robini), and whether the population growth of bulb mites is affected by F. oxysporum f. sp. cepae. We aim to present the results of the ongoing experiment and discuss their importance for the management of bulb mites and F. oxysporum f. sp. cepae in Norway.
