为了研究影响超甜玉米鲜穗产量和主要农艺性状间的主次关系。对20个超甜玉米自交系的11个农艺性状与鲜穗产量进行相关及通径分析。相关分析表明，鲜穗产量与穗长、行粒数、穗粗、百粒质量、穗行数呈极显著正相关，与出籽率呈显著正相关，与秃尖长呈极显著负相关。进一步进行通径分析表明，各性状对鲜穗产量的相对重要性依次为穗长、穗行数、百粒质量、穗粗、行粒数、出籽率和秃尖长。因此，增加穗长、穗行数，提高百粒质量和出籽率，并兼顾其他性状是提高超甜玉米自交系鲜穗产量的有效途径。

In order to investigate relations of primary and secondary on main agronomic characters which influ-encing fresh ear yield of super sweet corn inbred line ,Correlation and path analysis of fresh ear yield and 11 agro-nomic characters were made in 20 sweet corn inbred lines .The results of correlation analysis revealed that fresh ear yield correlated very significantly with ear length ,kernels per row,ear diameter,100-kernel weight,ear rows,the fresh ear yield correlated significantly with percentage of kernels .There was very significantly negative correlation between fresh ear yield and bare top length .The results of path analysis further indicated that the relative impor-tance of fresh ear yield in turn is ear length ,ear rows,100-kernel weight,ear diameter,kernels per row,percentage of kernels and bare top length .Therefore ,increasing ear length ,ear rows and enhancing 100-kernel weight and per-centage of kernels are the best efficient way to increase the fresh ear yield of super sweet corn inbred lines .At the same time,the other traits should be considered .
