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。
The selection of wild soybean, cultivated soybean and interspecific high-generation materials were made according to the different isoflavone content to prepare the cross combination, and the genetic analysis was conducted on the isoflavone content of the soybean and its offspring. The results showed that the F value of combining ability of soybean female parent reached a significant level, and the variance was decomposed into the general combining ability and special coordination of P1 (high, middle, low) and P2 (high, medium and low) parents of parental group Force variance and F test, found that the maternal group with the ability to test the variance F test reached a significant level, indicating that the measured trait of hybrid combinations by the parental gene additive effect, the parents of different combinations of general combining ability and special combining ability difference Big. In 33 soybean parents, the relative amplitudes of specific combining ability (-28.6% -32.5%) were the highest, and the combination of 32.5% (Longpin 05-277 × wild 01-177) An important reference combination for high isoflavone breeding goals. In soybean high isoflavone breeding, the parent is best to use high × high type configuration combination.
