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。
對7份子蓮材料的主要農藝性狀與產量進行相關及通徑分析。結果錶明：子蓮11箇主要農藝性狀與產量相關性彊弱為：蓮蓬數＞花託直徑＞單粒鮮蓮子質量＞單箇鮮花託質量＞平均心皮數＞鮮果實橫徑＞結實率＞葉柄粗＞鮮果實縱徑＞葉片長半徑＞葉柄高。其中，蓮蓬數、花託直徑和單粒鮮蓮子質量與產量呈極顯著或顯著正相關。從通徑分析結果來看，蓮蓬數、單箇鮮花託質量、結實率、平均心皮數對子蓮產量的影響主要取決于直接作用；花託直徑、鮮果實橫徑、鮮果實縱徑、葉柄粗對子蓮產量的影響主要取決于間接作用；而葉柄高、葉片長半徑、單粒鮮蓮子質量對子蓮產量的影響則通過直接和間接共同起作用。綜閤以上分析，提高子蓮產量的主攻方嚮是提高單位麵積蓮蓬數、單箇鮮花託質量、平均心皮數和結實率，同時兼顧花託直徑、單粒鮮蓮子質量的增加，併協調好它們之間的關繫。

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.
