摘  要:
采用双列杂交遗传交配设计,分析了10个玉米群体产量性状的配合力和杂种优势的关系。结果表明,憨头苞谷、Suwan1、辽旅群体和WBM等4个群体产量的一般配合力效应较高,是优良的群体种质,在育种上具有较大的利用价值。Suwan1×BSSS和Suwan1×Lancaster具有较高的杂交产量及特殊配合力效应值,为两个较优的杂种优势模式。

摘  要:
The diallel mating design was used to analyse the combining ability and heterosis of 10 popuations.The results showed that Hantoubaogu,Suwan1,Liaoluqunti and WBM had higher value of GCA effects on yield.They were the elite population germplasms and had important value about maize breeding research.Based on the special combining ability and hybrid level on yied of Suwan1 cross BSSS and Suwan1 cross Lancaster showed they were two elite heterosis patterns.
