| 摘 要： | 以四川省5个常用不育系和6个恢复系配制成的30个杂交组合和3个新品种共计33个组合为材料，运用主成分分析分析方法考察了产量及与产量有关的8个农艺性状（指标）与产量的相互关系。结果表明，改良以穗重为代表的穗部性状可以较为有效地改良产量组成系统，从而实现高产育种的目标。

| Abstract: | The associations among yield and yield components, and their direct and indirect influence on the grain yield of hybrid rice were investigated. For this purpose, 33 combinations made from the most commonly used breeding lines in Sichuan were tested in a randomized complete block experiment design with three replications. The 8 yield related traits or indexes were used as correlation, principle components analysis. The result shows that we can increase the yield through improve the panicle weight. |
