Abstract

The invention discloses a development method of a strawberry functional gene linked SSR marker. The development method comprises the following steps: (1) acquiring strawberry genome public data; (2) performing quality control processing on the data, assembling and splicing the processed sequences, and identifying a microsatellite sequence; (3) designing primers on a flanking sequence of the microsatellite sequence; (4) performing transcriptome sequencing, splicing and gene annotation of different strawberry varieties; and (5) carrying out electronic PCR anchoring on primers to specific genes.The SSR marker of the method has the advantages of high polymorphism, good codominance, good repeatability and the like. 2468 SSR markers and primers thereof are provided for strawberries, and the markers are all related to functional genes, so that a favorable tool is provided for strawberry breeding and gene mining related to agricultural traits.

Description

technical field

[0001] The invention relates to a screening method for molecular markers, in particular to a method for developing strawberry functional gene-linked SSR markers. Background technique

[0002] Molecular markers are genetic markers based on nucleotide sequence variation in an individual's genetic material. Molecular marker technology has been widely used in genetic map construction, phylogenetic analysis, population genetic analysis and so on. In recent years, the application of molecular marker methods in hybrid identification has become more and more common. Compared with morphological identification, molecular marker identification is fast, accurate and reproducible. With the development of molecular technology, there are more and more methods for molecular marker identification, and more than 60 molecular markers have been developed, including molecular markers based on traditional Southern hybridization, such as RFLP, SS-CP-RFLP, DGGE-RFLP, etc.; PCR-ba...
