Abstract

The invention relates to the field of aquatic product inheritance breeding, in particular to a construction method of Portunus trituberculatus fast-growth strain. The genome microsatellite of breeding materials are utilized to serve as molecular markers; according to the molecular marker, obtaining a group which has obvious reproductive isolation in hereditary constitution as a hybridization group, and carrying out hybridized combination to the hybridization group to obtain the Portunus trituberculatus fast-growth strain. The invention can utilize the species genetic resources to the utmost, which is favorable for more scientifically cultivating the Portunus trituberculatus fast-growth strain.

Description

technical field

[0001] The invention relates to the field of aquatic genetics and breeding, in particular to a method for constructing a fast-growing strain of Portunus trituberculatus. Background technique

[0002] The genetic breeding of aquatic animals is traditionally carried out by group selection or crossbreeding. At present, there are also attempts to learn from the method of family selection used in poultry storage. Due to the large amount of eggs laid by general aquatic animals and the large number of offspring, family selection and breeding are very cumbersome and difficult to operate. Group selection takes a long time and has slow results. In recent years, scholars at home and abroad have been paying great attention to molecular marker-assisted breeding, but in practical applications, especially in the genetic breeding of aquatic animals, no results have been achieved.
