Abstract:

With the development of gene sequencing technology,plant genome data are becoming more and more abundant. Single nucleotide polymorphism(SNP)data are widely used in the development and application of molecular markers because of their high density,high throughput and easy automated analysis. Kompetitive allele-specific PCR(KASP)is a high-throughput genotyping technology mainly based on SNP. Because of its high flux,low cost and strong operability,this technology has great application potential in the field of crop character improvement. This paper introduces the development,principle and method steps of KASP technology,summarizes the application of KASP technology in genetic breeding such as germplasm resource identification,molecular marker assisted breeding,gene mapping and seed purity identification of main crops,and discusses the advantages and disadvantages of KASP technology in order to provide reference basis for crop breeding research in the future.

Key words: KASP, high-throughput genotyping, genetic identification, molecular breeding, improvement of agronomic characters
