This work focuses on the ability of bread and durum wheat to accumulate selenium (Se) via a soil-addition procedure at sowing time. Total Se in mature-grain samples was determined by neutron activation analysis (cyclic and radiochemical). Results show that Se-supplementation at the top rate (100 g Se ha(-1)) can increase Se contents up to 2, 16, 18 and 20 times for Jordao, Roxo, Marialva and Celta cultivars, respectively, when compared to their unsupplemented crops. These findings do not preclude the need for weighing up an eventual trade-off between agrochemical costs, field logistics and Se recovery for alternative Se-biofortification methods.
