A major component rice variety of Xiangwanxian 9 (a late Indica variety) with 13.1%, 15.6% and 18. 3% of the moisture was respectively mixed with three ad-ditive varieties in 13% of moisture at ration of 7:3 for proce...A major component rice variety of Xiangwanxian 9 (a late Indica variety) with 13.1%, 15.6% and 18. 3% of the moisture was respectively mixed with three ad-ditive varieties in 13% of moisture at ration of 7:3 for processing assorted rices. Head rice recovery of the treatments was determined 24 hours later. Analysis indicated sig-nificant differences exist in the effects produced by the component varieties, their moistures and the component variety moisture.展开更多
