| 摘 要： | 对7 份子莲材料的主要农艺性状与产量进行相关及通径分析。结果表明：子莲11 个主要农艺性状与产量相关性强
弱为：莲蓬数＞花托直径＞单粒鲜莲子质量＞单个鲜花托质量＞平均心皮数＞鲜果实横径＞结实率＞叶柄粗＞鲜果实纵径＞
叶片长半径＞叶柄高。其中，莲蓬数、花托直径和单粒鲜莲子质量与产量呈极显著或显著正相关。从通径分析结果来看，莲
蓬数、单个鲜花托质量、结实率、平均心皮数对子莲产量的影响主要取决于直接作用；花托直径、鲜果实横径、鲜果实纵径、
叶柄粗对子莲产量的影响主要取决于间接作用；而叶柄高、叶片长半径、单粒鲜莲子质量对子莲产量的影响则通过直接和间
接共同起作用。综合以上分析，提高子莲产量的主攻方向是提高单位面积莲蓬数、单个鲜花托质量、平均心皮数和结实率，
同时兼顾花托直径、单粒鲜莲子质量的增加，并协调好它们之间的关系。

| Abstract: | Correlation and path analysis was carried on the main agronomic characters and yield of seven
seed lotus（Nelumbo nucifera Gaertn） cultivars. The results showed that the degree of correlation between eleven
major characters and yield was：receptacle number＞receptacle diameter＞single fresh seed weight＞single fresh
receptacle weight＞average carpel number＞fresh seed width＞seed setting rate＞petiole diameter＞fresh seed
length＞leaf long radius＞petiole height. Among them，receptacle number，receptacle diameter and single fresh
seed weight were significant or very significant positive correlation with seed lotus yield. Based on the path analysis
results，receptacle number，single fresh receptacle weight，seed setting rate and average carpel number had
direct effect on seed lotus yield. The receptacle diameter，fresh seed length，fresh seed width，petiole diameter
had indirect effect on yield. Other characters like petiole height，leaf long radius and single fresh seed weight had
both direct and indirect effects on seed lotus yield. Based on the above analysis，the principle breeding objectives
were to improve the receptacle numbers，single fresh receptacle weight，average carpel number and seed setting
rate per unite area. And the secondary objectives were increasing the receptacle diameter，single fresh seed weight
and well coordinating the relationship between them. |
