摘要
选用5个自交系为测验种,采用不完全双列杂交遗传交配设计,对四川盆地及盆周山区13个玉米地方种质的配合力进行了分析。结果表明:屏山大黄、筠连血丝和筠连大白马牙具有较大的利用潜势;13个地方种质可分为5个初级杂种优势群。根据特殊配合力(SCA)效应及产量表现,确定了旅大红骨×地方种质、热带种质×地方种质和PA亚群×地方种质是利用地方种质组配的强优势组合模式。
In the study, the combining ability of 13 landraces maize germplasms were analyzed using 5 inbred tests and incomplete diallel mating design of genetic. The results showed that pingshandahuang, junlianxuesi and junliandabaimaya had greater potential trend, 13 landraces were divided into five primary heterotic groups. Based on the experimental result, the main heterosis pattern landraces was summarized, that was Ludahonggu×landrace, tropical germplasm×landrace and PA×landrace.
