In view of the Daohuaxiang rice quality degradation year by year in Heilongjiang Province, quality chracteristics of Dao-huaxiang from different sources in Heilongjiang Province were analyzed. The objective was to find out the present variety quality of Daohuaxiang and to discuss factors which influence the variety quality of Daohuaxiang. The results showed that Daohuaxiang from the different sources due to different soil, fertilizer and rainfall conditions, presented different sensory quality. Daohuaxiang from Wuchang has higher sensory scores. Compared to control sample Kongyu 131, 75.00% of the samples showed superior scores to Kongyu 131, which indicated that the varieties of Daohuaxiang are of good quality. The protein content, amylose content, head rice rate, chalkiness rate, chalkiness degree, pasting temperature, peak time etc, have greater impact on the sensory quality of Daohuaxiang.
