Intercropping, based on the interplay between cereals and legumes, might be an encouraging approach to improve soil fertility and crop productivity and to guarantee more sustainable farming systems. However, plant consociation is also influenced by the interaction between roots and soil microbial communities, and different plant genotypes might differently respond to this management. Here, a 2-year field study was carried out, verifying the impact of intercropping and the inoculation with arbuscular mycorrhizal fungi (AMF) on two varieties of durum wheat, using a lentil variety as intercropped plant species, on wheat agronomic parameters and grain features, as well as on microbial communities of soil, rhizosphere and wheat roots. Results showed a genotype effect on diverse agronomic parameters, gluten quality and grain elemental concentrations. Additionally, intercropping and AM fungal inoculation affected and shaped the microbial alpha diversity and composition, especially for the AMF community, at root level. Overall, the effects of the considered treatments (intercropping with lentil and AM fungal inoculation) were noticeably influenced by the specific wheat genotype, suggesting the importance to conduct a careful selection of intercropped genotypes.

基于谷物和豆类之间相互作用的间作可能是提高土壤肥力和作物生产力以及保证更可持续的农业系统的一种令人鼓舞的方法。然而，植物结合也受到根系和土壤微生物群落之间相互作用的影响，不同的植物基因型可能对这种管理有不同的反应。在这里，进行了一项为期 2 年的田间研究，验证了间作和接种丛枝菌根真菌 （AMF） 对两个硬粒小麦品种的影响，使用扁豆品种作为间作植物物种，对小麦农艺参数和籽粒特性，以及土壤、根际和小麦根系的微生物群落的影响。结果显示基因型对不同的农艺参数、面筋质量和谷物元素浓度有影响。此外，间作和 AM 真菌接种影响并塑造了微生物 α 多样性和组成，尤其是根系 AMF 群落。总体而言，所考虑的处理（与扁豆和 AM 真菌接种间作）的效果受到特定小麦基因型的显着影响，这表明仔细选择间作基因型的重要性。
