Analysis of combining ability of the leaf roll degree in seedling period of maize

在干旱条件下,玉米苗期根冠比越大,耐旱性越强,叶片卷曲程度就轻。结果表明:515、226和524等自交系的耐旱能力最好,所配杂交组合的耐旱能力也较强,一般配合力相对效应较低;而260、540和438等自交系的平均耐旱能力最差,一般配合力相对效应较高。自交系苗期叶片卷曲度的遗传力达到66.3%,具有较高的遗传特性。...

Summary:在干旱条件下,玉米苗期根冠比越大,耐旱性越强,叶片卷曲程度就轻。结果表明:515、226和524等自交系的耐旱能力最好,所配杂交组合的耐旱能力也较强,一般配合力相对效应较低;而260、540和438等自交系的平均耐旱能力最差,一般配合力相对效应较高。自交系苗期叶片卷曲度的遗传力达到66.3%,具有较高的遗传特性。
