Abstract: To evaluate the zinc content of north rice materials comprehensively, 137 rice germplasms from Heilongjiang Province were analyzed using ICP- MS method in field experiment. The results showed that, under the same condition, the difference of rice germplasm zinc content from Heilongjiang Province was significant. The variation ranged from 10.92-25.47 mg/kg with the mean values of 16.15 mg/kg and the ratio of the maximum and minimum was 2.33. The result of frequency analysis of 137 rice germplasms zinc content showed unimodal normal distribution. The difference analysis was done in 4 accumulated temperature zones of Heilongjiang Province, the results of zinc content mean value patterns showed that zone 3>zone 4>zone 2> zone 1. L6, L170 with high level of zinc content were selected. These works will provide theoretical basis for reasonable utilization of local germplasm and new variety breeding in Heilongjiang Province.
