The invention discloses an
InDel marker for identifying red pulp characters of pears, a primer and application of the
InDel marker. The
InDel marker is located at the 4851722-4852014 bp position of a
chromosome 5 of a red fragrant
pear genome, and the overall length of the InDel marker is 292 bp. By utilizing the InDel marker and the method, the pulp color of the
hybrid generation of the
hybrid combination of the red-peel red-pulp parent and the green-peel white-pulp parent can be quickly and accurately identified in the
pear seedling stage through conventional molecular detection, and the green-peel white-pulp pears and the
hybrid generation of the red-peel red-pulp pears are efficiently distinguished. The method disclosed by the invention can be used for detecting each tissue, organ and each development stage of the
plant, has the advantages of convenience, rapidness, good specificity, high accuracy, no influence of climate environment and the like, can be used for early auxiliary selection of the
phenotype of the red
flesh of the
pear plant, can greatly improve the breeding selection efficiency and accuracy of the red
flesh pear variety, and has a wide application prospect. The blank in the field of pear
plant red pulp character
molecular marker development is filled up, and great promotion significance is achieved for pear
germplasm improvement and fruit value improvement.
