Molecular marker of major QTL (quantitative trait loci) qFC5.1 for regulating flavone content in mature period of rice and application of molecular marker

The invention belongs to the technical field of rice breeding and molecular biology, and particularly relates to a major QTL for regulating and controlling the flavone content in the rice mature period and application of the major QTL. The invention provides a major QTL (Quantitative Trait Locus) for regulating and controlling the flavone content in the mature period of rice, and the major QTL is named as qFC5.1, the major QTL is positioned on a chromosome 5, the genetic distance of the major QTL is 28.61 to 30.26 cM, the physical distance of the major QTL is 6673100 to 7059585 bp, and the LOD (Like of Detail) value reaches 4.13. By developing the molecular marker closely linked with the major QTL, the related QTL for regulating and controlling the flavone content in the rice mature period in the rice variety or strain is detected. 本发明属于水稻育种及分子生物学技术领域，具体涉及一个调控水稻成熟期黄酮含量的主效QTL及其应用。本发明提供一个调控水稻成熟期黄酮含量的主效QTL，并将其命名为qFC5.1，所述的主效QTL被定位于5号染色体上，其遗传距离为28.61～30.26cM，物理距离为6673100～7059585bp，LOD值达到4.13。通过开发与所述主效QTL紧密连锁的分子标记
