1. With purposes of examining the milling yield and quality of milled rice and of classifying the quality of milled and brown rice, milling tests were carried out in condition of 94 % milling over the rice samples selected from the adapted prefectures representing each block. 2. As to the milling yield and quality of milled rice, there are some significant differences among the grades and blocks, too. The exiting grading of rice is not necessarily reasonable because of the a/m significant differences among the grades. 3. Qualities of brown rice have connection with the quality of milled rice and respects with milling yield. And this point was figured out by way of calculating their correlation coefficients and of analysis of variances.
