Breeding method of pure-black-hair-color pig breeds

Abstract

The invention provides a breeding method of pure-black-hair-color pig breeds. The method is mainly characterized in that the specific loci (the 708bp locus, 730bp locus and 788bp locus of the MC1R*31gene) of male parent and / or female parent pig breeds are detected, and offspring pig hair color can be predicted accurately by judging genotype to obtain the pure-black-hair-color offspring.

Description

technical field [0001] The invention relates to the field of pig genetics and breeding, in particular to a rapid molecular breeding method for producing black offspring breeding pigs or commercial pigs. Background technique [0002] In the past few decades, the genetic improvement of pigs has mainly focused on improving the carcass performance such as growth rate and lean meat percentage, ignoring the improvement of pork quality, which has led to a sharp decline in meat quality while the carcass performance of pigs has been greatly improved. Taste worse. With the development of social economy, the improvement of people's living standards and the change of consumption concept, the consumer group and market structure of pork have also undergone obvious changes, and the demand for high-quality pork products with good meat quality and good flavor is increasing day by day. [0003] Local pig breeds in my country have the advantages of good meat quality, good flavor, and strong s...

Problems solved by technology

However, this traditional breeding technology has a long cycle, and it usually takes 6 to 8 generations or even longer to fix the expected coat color of the offspring of the breeding material. Accurately predicting the separation of offspring's hair color is inefficient and costly, which seriously affects and restricts the breeding process of specialized strains and new varieties (matching lines)
