Problems solved by technology

In terms of the reasons, apart from the deteriorating breeding environment and backward breeding technology, there is another important reason: no attention has been paid to the selection and preservation of seed oysters for many years, and there is a lack of good varieties; , such as slow growth, small size, weakened pearl breeding ability, etc.

Embodiment 1

[0030] Randomly take 96 Pinctada martensii individuals from the same group, after cleaning, measure the shell size (shell height, shell length, shell width and hinge line length) with an electronic digital caliper, and weigh it with an electronic balance The weight of the soft body and the adductor muscle tissue were taken, and recorded one by one, and then a small piece of adductor muscle tissue was taken respectively, placed in 95% ethanol, and stored at -20°C. Genomic DNA from the adductor muscle of 96 Pinctada martensii individuals was extracted using the HiPure Universal DNA Kit (Guangzhou Meiji Biological Co., Ltd.). For related operations, refer to the kit instructions. After the DNA was extracted, its integrity was detected by electrophoresis on 1.0% agarose gel, and the concentration and purity of the DNA were measured by an ultraviolet spectrophotometer, and stored at -20°C.

Abstract

The invention discloses a SNP411871 marker associated to shell mould and weight of pinctada martensii, a primer and an application thereof. The primer comprises 411871FI: GGAAACGGAATTCACATTCATTATCTTTA; 411871RI: AATGTCAAGCTGGATATAATTTAGCTCTA; 411871FO: AAATTATTGAAACTATTTCACCGATTCG; and 411871RO: TTGTGATTTCATTTTCGTATCAATATTCTT. According to the invention, a specific SNP genotype site can be amplified by the primer, size of individual shell length and hinge line length as well as weight of soft part and adductor muscle can be visually compared according to a PCR electrophoretogram, nd the primer can be directly used for subsequent molecular mark assisted breeding.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquatic animal genetics and molecular marker assisted breeding, and specifically relates to a SNP411871 marker associated with the shell shape and weight of Pinctada martensii, as well as primers and applications. [0003] Background technique: [0004] Pinctada martensii is the main species of pearl culture in my country and the world. Since the successful artificial breeding of Pinctada martensii in my country in 1965, the seawater pearl industry has developed rapidly and has become one of the pillar industries of mariculture in Guangdong, Guangxi and some coastal areas of Hainan. In the past 10 years, the quality and output of seawater pearls in my country have declined significantly, the international competitiveness has weakened, and the economic benefits of breeding have declined. In terms of the reasons, apart from the deteriorating breeding environment and backward breeding technology, the...
