| Abstract | We aimed to clarify whether low cadmium (Cd) accumulation in varieties of rice also lower human nutrient uptakes.This trial was setup to explore the correlation between grain-Cd and iron (Fe) and zinc (Zn) among four promising rice cultivarsand the prevailing KDML105 and RD6. Their grain Cd (0.100.60 mg kg-1) and Zn (17.3622.61 mg kg-1) contents were significantly different, but not significant for grain Fe (11.1713.91 mg kg-1). The results revealed significant positive correlationsbetween grain Cd and Zn of the prevailing cultivar (r=0.471). But no correlations between grain Cd and Fe and Zn wereobserved. The RD15 and KNU2 were identified as the low grain Cd, high grain Fe and Zn compared with the prevailing cultivar.Thus the RD15 and KNU2 led to reduced Cd in rice grain without changing the human essential elements. |
