The invention discloses peanut
oligonucleotide probes and their design method and use method. The peanut
oligonucleotide probes comprise eight probes having
nucleotide sequences shown in the formulas of SEQ ID NO. 1 to NO. 8. The
microsatellite and
telomere sequences are used for developing the
oligonucleotide probes, the novel oligonucleotide probes are combined into a probe set and oligonucleotide types of the peanut
cultivar and wild peanut are constructed, an economic, efficient and high universality peanut cytological marker design technique and
chromosome recognition technique are built, peanut
chromosome markers are enriched, genomes and chromosomes of the peanut
cultivar and wild peanut are identified, and chromosomal
structural variation of wild peanut species is identified. Through use of a high-
throughput small data simplified sequencing (for only measuring the amount of genomic 4Gb data) and
bioinformatics analysis, peanut oligonucleotide probe markers are successfully developed. The invention provides a novel
effective method for low-cost and high-efficiency development of peanut cytological markers.
