Abstract：The object of the present study was to investigate ten necessary mineral elements in different varieties of rapeseed by ICP-MS. Thirty three samples of double-low (low in both glucosinolates and erucic acid) rapeseed (DLR) and 12 samples of double-high rapeseed (DHR) in the Yangtze River Valley were collected. The results showed that rapeseed contained many kinds of necessary elements, and there was a difference between DLR and DHR. The average concentrations of P, K, Ca, Mg, S, Fe, Mn, Cu, Zn and B in DLR were 6.26 mg·g-1, 10.17 mg·g-1, 6.75 mg·g-1, 4.82 mg·g-1, 4.52 mg·g-1, 96.20 μg·g-1, 37.10 μg·g-1, 3.84 μg·g-1, 41.61 μg·g-1 and 12.16 μg·g-1, respectively, while for the mineral elements in DHR, the average values were 5.97 mg·g-1, 10.14 mg·g-1, 6.31 mg·g-1, 4.50 mg·g-1, 9.06 mg·g-1, 77.03 μg·g-1, 49.86 μg·g-1, 3.72 μg·g-1, 40.58 μg·g-1 and 11.79 μg·g-1. The contents of most elements in DLR were higher than those in DHR, such as P, K, Ca, Mg, Fe, Cu, Zn and B. Furthermore, the differences in Ca, Mg and Fe contents between the two varieties were significant. It was concluded that the difference in concentrations of mineral elements can be regarded as a necessary factor for popularizing double-low rapeseed in the Yangtze River Valley.
