Abstract: Corn parents YE478 and DAN340 were crossed to produce their first generation which were then inbred to produce 345 F3,4recombinant inbred lines（ RIL）. The parents,F1 and F3,4were used as the material to determine 6 traits in the corn ear,ie. ear length（ EL）,spike thickness（ ED）,kernel row number（ KRN）,kernel number per row（ KRE）,dry seed weight（ DSW）,hundred grain weight（ 100-GW）. These 6 traits were then placed for analysis of variance,correlation analysis and normality test. Results show that all traits except the 100-GW in the 345 lines were genetically different in reality. All the 6 traits were quantitatively genetic in the F3,4lines,and the values of their traits were close to those of their parents. The F3,4lines showed some transgressive segregations over their parents,and are hence good populations for genetic mapping.
