A detection of SNP markers associated with the growth traits of Abalone and its application

Abstract

The invention discloses a SNP marking detection associated with growth trait of haliotis diversicolor and an application. The molecular marker is gene sequence shown as SEQ ID NO.1. The invention further discloses a primer AMY-FP and a primer AMY-EP for detecting the molecular marker; the primer AMY-FP is the sequence shown as SEQ ID NO.2, and the primer AMY-RP is the sequence shown as SEQ ID NO.3. The SNP site obtained through molecular marking, primer, and selection is applied to the selection and breeding of haliotis diversicolor. A parent is selected by using the primer and the method; the growth rate of the later breeding generations is obviously higher than the unselected control group; the molecular marker and the primer can efficiently, rapidly and simply be applied to the selection and breeding of haliotis diversicolor.

Description

technical field [0001] The invention relates to a SNP marker detection associated with the growth traits of abalone and its application, and belongs to the technical field of aquatic animal genetics and molecular marker-assisted breeding. Background technique [0002] Nine hole abalone ( Haliotis diversicolor supertexta ), also known as variegated abalone, belongs to the mollusk phylum, gastropod class, and abalone family. Abalone is known as the "Eight Treasures of Seafood" because of its well-developed abdomen and legs, delicious meat and high nutritional value. The research on the artificial breeding and breeding technology of Chinese abalone began in the 1970s. In the mid-1990s, due to the introduction of industrial abalone breeding technology, the artificial breeding of abalone became industrialized and gradually became an indispensable part of the aquaculture industry in southern my country. of cultivated species. However, with the rapid development of the abalone aq...

Problems solved by technology

However, with the rapid development of the abalone aquaculture industry, the occurrence of diseases during the seedling and growing period has become more and more frequent

In addition, in the process of abalone breeding, the selection of parental abalone and the improvement of seedling technology are not paid attention to, resulting in the inbreeding of abalone and the continuous decline of species germplasm, which has caused huge economic losses to the abalone aquaculture industry and seriously inhibited the healthy development of my country's abalone industry.
