Abstract
The present invention relates to the field of agricultural biotechnology, and in particular to the Zm00001d029550 gene for regulating the oil content of corn kernels and its application. The present invention uses the temperate corn inbred line Ye107 with low kernel oil content as a common parent, and crosses it with 5 tropical and subtropical corn inbred lines with high kernel oil content, to construct a corn multi-parent population with significant differences in kernel oil content. GWAS analysis and genetic linkage analysis are used to co-locate SNP_75791466 located on chromosome 1, which is significantly related to kernel oil content, and then the functional gene Zm00001d029550 for regulating kernel oil content is excavated, and the gene can explain 1.4% of the phenotypic variation of kernel oil content. The results of the present invention are helpful to further study the regulatory mechanism of kernel oil content in corn, and also provide technical support for breeding high-quality high-oil corn varieties.
