摘　　要：丹9046和C8605-2是基础来源完全相同的两个优良玉米自交系,分析其主要农艺性状配合力的结果表明:丹9046和C8605-2的表现各有所长。对于一般配合力,C8605-2的单株产量、百粒重、秃顶率、穗粗等4个性状都优于丹9046,而丹9046在出籽率、穗长和行粒数等3个性状上略高于C8605-2。而特殊配合力,应继续加强丹9046(C8605-2)×黄改系、丹9046(C8605-2)×旅大红骨等杂优模式的研究和利用。C8605-2and Dan9046were two maize self-lines of the same basis source.To analysis their ten main agronomic characters,the results showed that C8605-2and Dan9046each had their own strong points in com-bining abilities.The general combining abilities of C8605-2was better than ones of Dan9046in yield per plant,100-grain weights,ear diameter and bear lip percentage,but in ear length,kernel number per row,and kernel weight percentage per ear,Dan9046was slightly better than C8605-2.The cross models,Dan9046(C8605-2)×huanggaixi and Dan9046(C8605-2)×Ludahonggu,must be studied.
