Identification of High- and Low-Cadmium (Cd)-Accumulating Rice Cultivars Using Combined Molecular Markers.

ABSTRACT: Rice grain is a primary dietary source of cadmium (Cd), a heavy metal toxic to humans. Reducing Cd accumulation in rice through selecting and breeding low-Cd-accumulating cultivars is very important. However, field-based screening for low-Cd rice cultivars remains labor-intensive and time-consuming. In this study, we identified molecular marker genotypes that can distinguish high- and low-Cd-accumulating rice cultivars. We developed corresponding genotypes for marker-assisted selection of low-Cd cultivars in both early and late rice varieties. Fifty-nine locally adapted, high-yielding early rice cultivars and thirty-seven locally adapted, high-yielding late rice cultivars were grown in two fields with different soil Cd levels and genotyped using molecular markers associated with grain Cd a
