摘要
对广东省１７２个栽培稻品种１０项米质性状的相关分析结果表明，总评分与角质率、胶稠度、米饭品尝评价、整精米率、粒长和糙米率呈很显著的正相关，与垩白粒率、粒宽和直链淀粉含量呈很显著的负相关。通径分析表明，对总评分贡献最大的为角质率，其次为粒长宽比、米饭品尝评价、直链淀粉含量、整精米率和胶稠度；在间接作用中。
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.
