Litchi embryo character SNP molecular marker developed based on KASP technology and application thereof

The invention belongs to the technical field of molecular bioengineering, and particularly relates to a litchi embryo character SNP molecular marker developed based on a KASP technology and application of the litchi embryo character SNP molecular marker. The SNP molecular marker is located at a 41766403bp base of a first chromosome of litchi, the base is G or C, if the base is C genotype, it is judged that the embryo character of the litchi is a variety with a large nucleus or a low scorch nucleus rate, and if the base is G genotype, it is judged that the embryo character of the litchi is a scorch nucleus type or a small nucleus type. The universal and stable SNP molecular marker is developed by utilizing genome re-sequencing data of litchi resources to carry out linkage imbalance analysis and whole genome association analysis, combining field phenotype data to locate to SNP sites remarkably related to scorched nucleus traits in a population, and then utilizing a KASP genetic typing method.
