Abstract
Correlation and path analysis of fresh ear yield and 10 major quantitative characters of fresh-eaten glutinous maize were made.The results showed that the fresh ear yield were significantly positively correlated with the average weight of ear,ear length,ear diameter,the number of kernel per row,axis diameter and 100-grain weight,the correlation coefficient were 0.615,0.523,0.443,0.392, 0.364 and 0.341.The fresh ear yield was significantly positively correlated with plant height,the correlation coefficient was 0.315.Among those characters,the greatest contribution to fresh ear yield was the average weight of ear,the efficient was 0.4518.The second was axis diameter,the efficient was 0.3681.Other characters were 100-grain weight,ear diameter,ear height,ear length,plant height,rare ear length,the number of kernel per row,the number of row per ear.
