摘要：本实验采用双列杂交的方法按照P（P-1）/2对9个不同的亲本材料进行配合力分析，结果表明：EGM、云油199、沈137等亲本材料的一般配合力高，EGM×云油199、沈137×云油199、T8×EGM等组合的特殊配合力高.从对各性状遗传参数的分析结果可知,各性状主要受加性基因遗传影响,而受环境条件的影响较小,均能较真实地将亲本的这4个性状遗传给杂交一代。

In this experiment,I have analysised 9 different parent materials in double cross hybrid method according to the formula of P (P-1) / 2.The results showed : EGM,yunyou-199,shen-137 and other parent materials had high combining ability;The combination EGM ×yunyou -199, shen -137 × EGM × yunyou-199 and T8×EGM had high special combining ability. According to the results of the genetic parameters of each Trait, all Traits were mainly impacted by additive genetic effects,and lessconditions of environmental,It was descended from parents to F1.
