Development of melon KASP markers and construction of fingerprints
To enrich spectrum of molecular markers in melon and offer a straightforward and efficient protocol for the sub-sequent identification of melon germplasm,variety,and seed purity,this investigation identified six pivotal single-nucleo-tide polymorphism(SNP)loci distributed across the melon genome,encompassing a total of 72 markers.Utilizing the KASP(kompetitive allele-specific PCR)assay,these markers were employed to genotype 11 melon germplasm acces-sions,resulting in the identification of 45 marker pairs exhibiting superior typing performance.The success rate of marker design reached 62.5%,and from these 45 pairs,the most optimal markers for the 25 identified genetic clusters were select-ed,and the polymorphisms of 31 muskmelon germplasm were divided into 3 groups,and the fingerprints of 31 muskmel-on germplasm were constructed to provide reference for the utilization of muskmelon germplasm resources and seed puri-ty identification.
