Genotypic differences among rice cultivars in lead accumulation and translocation and the relation with grain Pb levels

► Grain Pb concentrations were in the order Hybrid Indica>Indica>Japonica. ► Grain Pb concentrations correlated significantly with shoot Pb concentrations. ► Pb TF from shoots to grains were in the order Hybrid Indica>Indica>Japonica. ► Grain Pb concentrations correlated significantly with Pb TF from shoots to grains. ► Pb concentration in ears of heading can be an index of Pb level in the grains.
