摘　　要：通过对15个水稻品种在13个试验地点的播种试验,分析稻米品质诸性状在不同生态地点下的变异特征,并利用典型相关分析方法对影响稻米品质的主导气象因子进行了分析,结果表明:稻米品质的性状可根据变异系数的大小划分为6个类型,其中垩白度、垩白粒率对生态条件的变化最敏感,整精米率、胶稠度、直链淀粉含量和糊化温度居中;影响稻米品质的主导气象因子为日均温度和日均温差。Based on the experiment with 15 varieties in 13 areas, the variable parameter of 10 quality traits among 13 areas, also the important Meteorological factors upon the quality traits were analyzed by typical correlation analysis. The results showed that 10 quality traits could be divided into six types according to its variation coefficient, in which chalkiness degree and Chalky rice rate was sensitive; the important Meteorological factors upon the quality traits were daily mean temperature and daily mean temperature differentce.
