Soybean identity important character SNP (single-nucleotide polymorphism) marker combined screening method and application thereof

The invention discloses a soybean identity important character SNP (single-nucleotide polymorphism) marker combined screening method and application thereof. The invention provides application of a substance for detecting 14 SNP sites in identifying soybean germplasm. The invention provides an accurate reliable germplasm resource identification system which is simple and easy to implement. The system has wide identification adaptability, and is used for identification analysis on the soybean germplasm resources in different ecological regions in China, and the identification efficiency is up to 70% or above. The system doubtlessly has an active action on crop species resource management and species protective utilization and evaluation, and provides scientific references for crop new species authorization and germplasm material evaluation.
