| Abstract: | The statistical methods of correlation analysis, path analysis and combination of path analysis with stepwise regression are used to study the basic characters of high-yield genotype in corn hybrid populations. The results have shown that high-yield genotype gives thicker and longer ears, heavier grain weight, suitabale plant height and upright leaves. |
