A genetic molecular marker and application for fast-growing sea cucumber breeding

Abstract

The invention discloses a genetic molecular mark for fast-growing stichopus japonicus breeding and application thereof, and belongs to the field of aquatic product genetic breeding. The molecular markis an SNP160 mark; the amplification molecular mark is an SNP160 primer pair: SNP160F: 5'-TCGCAGGAAACCAACCTTCA-3' and SNP160R:5'-AAGGGAGGGTCAAGGAGGAT-3'. The mark is used for fast growing the property auxiliary breeding advantage genotype of AA. Meanwhile, the invention also discloses the auxiliary breeding steps of the mark. The effective molecular mark is provided for the economic property of the stichopus japonicus growth in the genetic aspect; when the genetic mark is used for mark auxiliary selection and developing the genetic breeding, the growth speed of seedlings can be effectively accelerated; important significance is realized on improving the culture benefits.

Description

technical field

[0001] The invention belongs to the field of aquatic genetics and breeding, and in particular relates to a genetic molecular marker for fast-growing sea cucumber breeding and its application. Background technique

[0002] Sea cucumber belongs to Echinodermata phylum Echinodermata and sea cucumber class Holothuroidea, and is one of the important sea treasures in northern my country. In recent years, sea cucumber farming in my country has developed rapidly, and its scale has expanded rapidly. The direct economic output value is about 30 billion yuan. It is the species with the largest single output value in my country's mariculture industry. important way. However, with the continuous expansion of the scale of the sea cucumber industry, a series of bottleneck problems that restrict or potentially restrict the development of the industry, such as germplasm degradation, slow growth, long breeding cycle, poor ability to resist environmental changes, and frequent d...
