Abstract:

Fiber and wool quality not only affects the economic benefits of cashmere goat breeding, but also affects the quality of wool textiles. In recent years, fluff quality has declined with cashmere yield improvement. In order to improve production efficiency, improving fluff quality is imperative in the production process. At the same time, fiber and wool quality is important parameters of selection in breeding of goats. The main traits of controlling the fluff quality are quantitative traits. It can be to find the number of main effect genes by quantitative genetics and molecular genetics and to study its growth mechanism and gene expression. In this review, we summarize the recent achievements of the quality of cashmere, including the use of phenotypic select to improve the quality of the fluff and finding the genetics of controlling the quality of cashmere, for example, HOX,BMP,KAP genes and pigments, and beginning to find the corresponding control target trait QTL and different sequences of SNPs by GWAS analysis to improve the quality by genotype selection, in order to improve the quality of cashmere and provide reference to study the cashmere quality of genetic factors for later research.

Key words: fiber and wool quality; phenotypic selection; gene families; QTL technology; GWAS analysis
