摘要
9个玉米自交系(P1组:478、S108、AS201、S104;P2组:N04、FS5-4311、N21、N28、N31)按不完全双列杂交配制20个杂交组合,对其粒重、穗长、穗粗、秃尖长、穗行数、行粒数、千粒重7个性状的配合力进行了研究。结果表明:多数性状一般配合力存在显著差异,符合育种要求的自交系有FS5-4311,N28,S108,S104,可在育种中利用,优良组合有S108×FS5-4311、S104×N28、S108×N21、S104×N31、AS201×N04、478×N31,可进一步试验筛选。
By using the nine inbred lines of maize(P1:478、S108、AS201、S104;P2:N04、FS5-4311、N21、N28、N31),20 crosses were made according to incomplete diallel crosses of 4 ×5.The combining ability of seven traits were studied.The results showed the general combining ability of most traits were significantly different. The inbred lines FS5-4311, N28,S108 and S104 conformed to the requirements and can be used in breeding. The excellent crosses were S108 ×FS5-4311,S104×N28,S108×N21,S104×N31,AS201×N04 and 478×N31 can be further tested and screened.
