Embodiment Construction

[0027] Below in conjunction with accompanying drawing, invention is described in further detail.

[0028] 1. Sample selection:

[0029] In this study, 3-year-old ewes of Inner Mongolia cashmere goats were collected, a total of 192 individuals. At the same time, cashmere fiber samples and ear tissue samples were collected for fiber diameter measurement and DNA extraction, respectively.

[0030] 2. Measurement and analysis of cashmere fiber fineness

Abstract

The invention discloses a molecular marker influencing the cashmere length character of cashmere goats and application of the molecular marker. The site of the molecular marker comprises G>A mutationcorresponding to the 19532160 position on the No.2 chromosome of the goat genome ARS1 version. By the molecular marker, cashmere goats with relatively long cashmere can be rapidly and efficientlyscreened out, the cashmere quality and yield can be improved, genetic improvement can be rapidly and efficiently implemented for the cashmere goats when the molecular marker is applied to a breeding technology, and thus the market competitiveness of cashmere goat breed is improved.

Description

technical field [0001] The invention relates to the technical field of molecular marker-assisted selection and animal genetic breeding, in particular to a molecular marker affecting the length traits of cashmere cashmere and its application. Background technique [0002] Cashmere goat is a unique biological resource in the world, with important economic value, and the products are rich and diverse, the main product of which is cashmere. Its fabrics are internationally renowned for their warmth, softness, smoothness and elegant shapes. Inner Mongolia cashmere goat is an excellent local breed bred through long-term natural selection and artificial selection. The goat's body surface is symbiotic, mainly composed of wool produced by primary hair follicles and cashmere produced by secondary hair follicles. Cashmere is thin and soft, white in color, delicate and smooth in hand, and is a treasure of fiber textiles. It is known as "fiber gem" and "soft gold" and is sold all over t...
