Abstract: The effect of different germinating conditions on rice qualities and RVA profile character of rice were studied with artificially induced conditions for the germination of rice grain which three vareities of rice were used. The result are as follow: sprouting seriously impact on the quality of rice, resulting in the rate of decline in brown rice, milled rice and the head milled rice, and chalky grain size of the rate and chalkiness increase, and Gel consistence decrease and Alkali spreading value decrease，and crude protein content decrease, especially, the rate of the head milled rice droped by the largest and the biggest drop more than 50%,so it’s seriously affected milling quality, appearance quality, cooking and nutritional quality of rice; Germination also made RVA profile character of peak viscosity(PKV) and breakdown value(BDV) decrease, reducing the eating quality of rice.
