| 摘 要： | 对构成杂交水稻产量的相关性状进行了分析，结果表明在构成产量性状的相关因素中，灰关联系数结实率〉播始历期〉千粒重〉株高〉穗长〉有效穗〉穗均粒数，表明结实率、生育期和千粒重三者对产量影响较大。试验结果以期为高产杂交稻的选育提供参考。

| Abstract: | The grey correlation analysis of yield and its components of hybrid rices showed that thecorrelation degree in size was ranked： seed setting〉 days of sowing to heading 〉 lO00-grain weight 〉 plant height〉 panicle length〉 effective panicle number〉 spikelet number per panicle, indicating that seed setting,days of sowing to heading and lO00-grain weight had a great influence on grain yield. The results could provide theoretical basis for breeding high,yielding hy- brid rice combinations. |
