Abstract
An association study conducted on 375 maize inbred lines indicates a strong relationship between Vgt1 polymorphisms and flowering time, extending former quantitative trait loci (QTL) mapping results. Analysis of allele frequencies in a landrace collection supports a key role of Vgt1 in maize altilatitudinal adaptation.
摘要
对375个玉米自交系进行的关联研究表明，Vgt1基因多态性与开花时间之间存在密切关系，扩展了先前的数量性状位点（QTL）定位结果。对地方品种群体中等位基因频率的分析支持了Vgt1在玉米高低纬度适应性中的关键作用。
