摘要
选用野生大豆、栽培大豆及种间高世代材料按异黄酮含量不同配制杂交组合,对亲本和后代大豆籽粒异黄酮含量进行遗传分析。结果表明：大豆母本配合力F值均达到显著水平,将方差分解成母本组P1（高、中、低）和父本组P2（高、中、低）亲本的一般配合力及特殊配合力方差并进行F测验后发现,母本组一般配合力方差F测验达到了显著水平,表明杂交组合所测性状受到亲本基因加性效应影响,亲本不同组合的一般配合力和特殊配合力差异较大。33个大豆亲本组合中,特殊配合力相对效应值的变幅为-28.6%~32.5%,效应值最高的组合（龙品05-277×野01-177）为32.5%,该组合可作为实现高异黄酮育种目标的重要参考组合。在大豆高异黄酮育种中,亲本最好采用高×高类型配置组合。
In order to broaden genetic basis of soybean and enhance breeding efficiency,36 hybridized combinations were designed according to isoflavone content（high and low）.Heritability and combining ability effect of isoflavone content was analyzed.The difference of female parent combining ability level was significant with F test.General combining ability variance of female parent was significant with F test when the variance was resolved into female parent group and male parent group according to isoflavone content（high,middle and low）.Both additive and non-additive effect of parents for isoflavone content were exist in these combinations.Range of specific combining ability was-28.6%～32.5%,with Longpin 05-277×Wild 01-177 the highest.For high isoflavone breeding,parents combination of high×high should be selected.
