This study was conducted to make breeding program for improving milling traits, which has difference among the rice varieties. Milling traits such as residual embryo ratio, broken kernel ratio and whiteness were investigated at the different milling level and with several varieties. Residual embryo ratio and broken kernel ratio were high at the varieties group having more 1000-grain weight. In the whiteness of milled rice, there was also variance among the varieties at the same degree of milling. Correlation analysis among milling traits showed that there is positive correlation between 1000-grain weight and recovery of brown rice, but negative correlation between protein content of brown rice and hardness of kernel. Therefore, these different milling traits of each varieties could be considered in the rice breeding program for the good quality.
