对广东省栽培稻的米质性状调查并进行相关分析的结果表明，米质性状香稻优于晚稻，晚稻优于杂交稻，杂交稻稍优于早稻。影响米饭品尝评分的米质性状正相关关系依次是胶稠度＞角质率＞粒长宽比＞粒长＞整精米率＞糙米率，负相关关系依次是垩白率＞粒宽＞直链淀粉含量。各因素之间又存在一定的相关性 The investigation on the quality traits of cultivated rice in Guangdong Province and the correlation analysis showed that the rice quality traits were better than the late rice, the late rice was superior to the hybrid rice, and the hybrid rice was slightly better than the early rice. The positive correlations of the rice quality traits that affected the rice tasting scores were gel consistency> cutin> grain aspect ratio> grain length> milled rice percentage> brown rice percentage, and the negative correlations were chalkiness rate> grain width> amylose content . There is a certain correlation between the various factors
