为探明水稻千粒重与外观品质性状的相关性，进而为水稻大粒品种的选育提供理论参考，对鄂晚10号和大粒王组配的 F7代242个群体进行千粒重及外观品质性状的考察，运用 SPSS 17．0软件，进行相关性及通径分析。结果表明：千粒重与粒长、粒宽、粒厚及垩白粒率呈极显著正相关，粒长与长宽比、粒厚、垩白粒率呈极显著正相关，粒宽与长宽比呈极显著负相关，与粒厚、垩白粒率呈极显著正相关，长宽比与粒厚、垩白粒率呈极显著负相关，粒厚与垩白粒率呈极显著正相关。通径分析表明，粒宽对千粒重的作用最大，粒长次之。

In order to explore the relationship between 1 000-grain weight and appearance quality of rice,so as to provide a theoretical reference for large-seeded line breeding.The 1000-grain weight and appearance quality traits of 242 plants from F7 population of rice recombinant lines of cultivar Daliwang Ewan-10 were investigated using correlation and path analysis in this group.The results indicated that grain length,grain width,grain thickness and chalky rice rate had a significant positive correlation with 1 000-grain weight.Length-width ratio,grain thickness and chalky rice rate had a significant positive correlation with grain length.Grain width had a significant negative correlation with length-width ratio and had a significant positive correlation with grain thickness and chalky rice rate. Length-width had a significant negative correlation with grain thickness and chalky rice rate.Grain thickness had a significant positive correlation with chalky rice rate.The path analysis showed that grain width had the biggest action to 1000-gain weight,second is grain length.
