Abstract

The invention discloses a SNP marker related to the sweet-sour flavor traits of peach fruit and its application. The present invention provides the application of the g.1495589 site genotype detection material of the peach tree genome to be tested in identifying or assisting in identifying whether the fruit of the peach tree to be tested is an acidic phenotype; the g.1495589 site is 5 Chromosome No. 1495589 or Sequence 1 No. 601 Nucleotide. Based on the existing 284 sequencing and chip SNP marker data of peaches, the present invention carried out correlation analysis with phenotypic traits, and successfully located a sweet-acid-related SNP marker on chromosome 5, compared with the previous RAPD , AFLP, and SSR markers can increase the prediction accuracy to more than 85%, making the prediction result more reliable. Prediction of individual sweet-acid phenotypes at the seed stage improves selection efficiency and saves breeding costs.

Description

technical field

[0001] The invention relates to the field of biotechnology, and belongs to the fields of peach molecular breeding and biotechnology, in particular to a SNP marker related to the sweet-sour flavor traits of peach fruit and its application. Background technique

[0002] Peach (Prunus persica) fruit is rich in protein, sugar, dietary fiber, vitamins and other nutrients, and is deeply loved by consumers. The sweet and sour flavor of peach fruit is one of the important economic traits of peaches. According to the quality, it is mainly divided into sour and non-sour peaches. Peach originated in China, so the types and quantity of peach resources in our country are much higher than other countries, but the varieties with high economic value are all bred varieties, so the selection of new varieties is to improve the quality and output of peaches in our country important influencing factors. At present, the breeding of peaches is mainly to produce new varieties by c...
