Correlation and Path Analysis of Main Ear Characters and Yield of Per Plant of Maize Hybrid Contained with African Blood

Correlation and path analysis of maize yield of per plant and five ear characters were made in 8 maize hybrids contained with African blood.The ear characters and yield of maize hybrids is positivly correlated.Their relative coefficient in turn is:100-kernels weight,kernels number per row,ear length,row number,ear diameter.The path analysis on ear characters and yield of maize crosses indicated that the relative importance of ear characters in turn is 100-kernels weight,ear length,row number,ear diameter,kernals number per row.So in order to get higher yield of maize hybrids contained with african blood,we should select crosses that have higher 100-kernels weight,longer ear length and more row number.The selection standards of ear diameters and kernels number of per row can be properly relaxed.
