AI Technical Summary
Existing technologies cannot effectively guide the genetic improvement and breeding of pear fruit firmness, nor can they quickly identify the fruit firmness of different varieties, thus affecting fruit storage and shelf life.
A molecular marker (SV) closely related to pear fruit firmness was developed. The 286bp SV marker located 855bp upstream of the PyACS1 gene on chromosome 15 of the Red Pear genome was amplified by PCR using specific primers and detected by gel electrophoresis to rapidly identify fruit firmness.
This technology enables rapid identification of fruit firmness in different pear varieties during the seedling stage, providing a basis for the breeding and production of new pear varieties and improving the efficiency and accuracy of breeding.
