Fine mapping of major QTL qshgd1 for spontaneous haploid genome doubling in maize (Zea mays L.).

individuals. Nevertheless, 79 gene models were identified within this 25 Mb region. Additionally, 10 promising candidate genes, based on RNA-seq data, are described for future evaluation, while the narrowed down genome region is accessible for straightforward introgression into elite germplasm by BC methods.
