Thirty late-maturing maize hybrids were tested using a randomized complete block design.Correlation and path between yield and main agronomic characters was analyzed.The most contribution to the yield was from number of kernels per row and thousand-seed weight with p and r value（P0.4 = 0.8345^**,r =0.8056^**,P0.3 =0.5270^**,r =0.5849^**）.The correlation value showed highly significant differences at 1% level.The following was number of rows per ear,plant height and ear height.It was pointed out enhancing number of kernels per row and thousand-seed weight,increasing number of rows per ear properly and giving dual attention to main agronomic characters is an effective way to enhance the corn yield in late-maturing maize breeding of Jilin province.
