| 摘 要： | 对新育成的桂花香品系及目前广东优质稻生产中3个当家品种的主要穗部性状与农艺性状进行相关分析。研究表明，优质稻单株有效穗数与每穗实粒数呈极显著正相关。单株有效穗数、每穗总粒数、实粒数与冠层3片功能叶的叶宽、灌浆期叶面积指数（LAI）等显著或极显著的负相关；株高与千粒重呈极显著的正相关、与每穗实粒数和单株有效穗数呈负相关。试验结果说明，在一定株高范围内，适当增加冠层3片功能叶的叶宽、减小这3片功能叶的张角，同时增加叶面积指数、茎秆直径是优质稻株型改良的一个重点。 |

| Abstract: | The correlation of head character of the Guihuaxiang strain and other three cultivars of quality grain rice with their agronomic character was studied in the paper.The results indicated that the number of effective panicles had a significant positive correlation with the filled grains per panicle. The number of effective panicles, the spikelets per panicle and the filled grains per panicle were found to have a significant positive correlation with the width of the top three function leaves and the leaf area index (LAI) before and after heading. Every head character had a significant negative correlation with the openness of the top three function leaves.The plant height had a significant positive correlation with grain weight,a significant negative correlation with the number of effective panicle per plant and the filled grains per panicle. The result showed that 90 ~100 centimeter height of plant, by adding appropriately width of the top three functional leaves, reducing openness of these three leaves, adding LAI and the width of straw, would be the focal point of plant type improvement of quality rice varieties. |
