| 摘 要： | 对１４个常用玉米自交系及其９１个杂交后代的多个性状进行了研究，分析了自交系的遗传差异与杂交种产量、特殊配合力、杂种优势以及自交系自身产量之间的关系。结果表明，在自交系遗传差异分析结果与其亲缘关系相接近的情况下，自产系遗传差异与杂交种产量、特殊配合力、杂种优势之间均表现为正相关；自交系高产性状的筛选不影响其孀交后代杂种优势的筛选。

| Abstract: | The relationship between hybrid yield,specific combining ability,heterosis,line yield and the genetic difference of lines were analysis,based on characters study in 14 maize lines and 91 single crosses.The results are as follows:when the analysis results of line genetic difference and line genealogy relationship are analogous,there are positive correlation between hybrid yield,specific combining ability,yield heterosis and line genetic difference.And generally,heterosis of hybrid was not influenced by choice of line yield. |
