| 摘 要： | 利用2006和2007年连续2年4个e型杂交早稻品种分期播种资料,对单株有效穗、株高、穗长、每穗总粒数、结实率、千粒重和播始天数等主要性状与单株产量进行了相关分析和通径分析。结果表明:e型杂交早稻随着播种期提早产量呈增加趋势;单株产量不仅与单株有效穗、结实率和千粒重呈极显著的正相关,而且还与每穗总粒数和株高有显著的正相关;通径分析的结果则表明,单株有效穗对单株产量的直接作用最明显,其次是每穗总粒数和结实率,千粒重对产量有一定影响,但作用不明显,株高和穗长对单株产量的直接作用最小,穗长则是通过每穗总粒数来影响产量的。 |

| Abstract: | According to the sowing test data of four e-type hybrid early rice varieties during 2006~2007,the correlation and path analyses between single-plant yield and main traits were conducted.The results indicated that the yield exhibited an increasing trend when the sowing date went ahead.Yield per plant was significantly positively correlated not only with the effective spikes per plant,setting rate and 1000-grain weight(P<0.01),but also with the total grains per spike and plant height(P<0.05).Path analysis res... |
