Ten rice quality characters of 172 Cultivars of Guangdong Province were evaluateal by correlation and path analysis methods. The results of correlation analysis showed that the general score assumed significant postive correlation with the vitreousness, gel consistency, rice taste appraisal rate of head rice, rice grain length and rate of brown rice, and significant negative correlation with the rate of chalky grain, rice grain width and amylose content respectively. The results of path analysis showed that the vitreousness made the greatest contribution to the general score, then the ratio of rice grain length to width, rice taste appraisal, amylose content, rate of head rice and gel consistency. The vitreousness had the greatest indirect contribution to the general score through the rate of head rice.
