| abstract |
The invention discloses a TubB-4BSNP molecular marker related to the growth traits of Pinctada martensii and its application, and belongs to the technical field of molecular marker-assisted breeding; the site corresponds to the microtubulin TubB-4B gene of Pinctada martensii site, where the base is G or C. The SNP marker of the present invention is significantly associated with the growth traits of Pinctada martensii (shell height, shell width and shell weight), and is a new molecular marker. By determining the SNP locus genotype of Pinctada martensii to be tested, the Early selection of growth traits of Pinctada chinensis can shorten the breeding cycle, improve genetic progress, save production costs, and have obvious economic and social benefits. |
