Heavy metal excess in soil represents a critical problem for crop productivity. Among these pollutants, cadmium (Cd) is one of the most dangerous in terms of food-chain contamination. Two durum wheat near-isogenic lines (NILs) and 12 commercial varieties (cultivars Arcangelo, Aureo, Aziziah, Cappelli, Cirillo, Creso, Iride, Maestrale, Parsifal, Russello, Strongfield, and Svevo) of durum wheat were exposed to a nontoxic level of Cd to evaluate its concentration in grains, roots, and shoots, as well as effects on biomass production. Cultivar Iride showed the most interesting behavior because it stored large amounts of Cd in the roots, preventing its translocation to grains. On the contrary, Cirillo and Svevo genotypes were characterized by a high Cd concentration in the grains. Furthermore, a molecular characterization employing the ScOPC20 marker associated with the Cd uptake locus has shown the absence of the expected fragment in the Iride variety and in other varieties characterized by low Cd concentration, as well as the presence of it in high Cd-accumulating cultivars.

土壤中的重金属过量代表了作物生产力的关键问题。在这些污染物中，就食物链污染而言，镉是最危险的污染物之一。硬质小麦的两个硬质小麦近等基因系（NIL）和12个商业品种（品种Arcangelo，Aureo，Aziziah，Cappelli，Cirillo，Creso，Iride，Maestrale，Parsifal，Russello，Strongfield和Svevo）暴露于无毒水平评估镉在谷物，根和芽中的浓度以及对生物量生产的影响。品种Iride表现出最有趣的行为，因为它在根部存储了大量的Cd，从而防止了Cd易位到谷物中。相反，Cirillo和Svevo基因型的特征是谷物中Cd浓度高。此外，采用与Cd吸收位点相关的ScOPC20标记已显示，在Iride品种和其他以Cd浓度低为特征的品种中，以及在高Cd积累品种中，都没有预期的片段。
