The invention discloses an
InDel molecular marker for identifying pink and red peach blossoms, a primer pair and application of the
InDel molecular marker. An
insertion / deletion marker associated with the peach
petal pink / red character is found in the 1195107 bp region to the 1195114 bp region of the sixth
chromosome of a peach
genome, PCR amplification is performed on different peach
germplasm resources by using
specific primers with
nucleotide sequences as shown in SEQ ID NO.1 and SEQ ID NO.2, the
petal color of a
single plant with a stripe of about 159 bp is pink, the accuracy rate can reach 96.7%, and the detection result shows that the peach
petal pink / red character associated with the peach petal pink / red character is obtained. The petals of a
single plant without amplified bands are red, and the accuracy rate is 66.7%. When the
InDel marker is used for rapidly identifying the petal color character of the peach
hybrid offspring in the
seedling stage, the breeding
workload is reduced, and the InDel marker has the advantages of convenience, low cost and the like, and can be applied to production in a large scale.
