Abstract
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 .关键词
