Abstract. Over the past decades, average global wheat yields haveincreased by about 250 %, mainly due to the cultivation of high-yieldingwheat cultivars. This selection process not only affected aboveground partsof plants, but in some cases also reduced root biomass, with potentiallylarge consequences for the amount of organic carbon (OC) transferred to thesoil. To study the effect of wheat breeding for high-yielding cultivars onsubsoil OC dynamics, two old and two new wheat cultivars from the Swisswheat breeding program were grown for one growing season in 1.5 m deeplysimeters and pulse labeled with 13CO2 to quantify the amountof assimilated carbon that was transferred belowground and can potentiallybe stabilized in the soil. The results show that although the old wheatcultivars with higher root biomass transferred more assimilated carbonbelowground compared to more recent cultivars, no significant differences innet rhizodeposition were found between the different cultivars. As aconsequence, the long-term effect of wheat cultivar selection on soil organic carbon (SOC) stockswill depend on the amount of root biomass that is stabilized in the soil.Our results suggest that the process of wheat selection for high-yieldingcultivars resulted in lower amounts of belowground carbon translocation,with potentially important effects on SOC stocks. Further research isnecessary to quantify the long-term importance of this effect.
