Grass carp insulin receptor α subtype SNP molecular marker combination and its application

Abstract

The invention discloses a grass carp insulin receptor α subtype SNP molecular marker combination and its application. The grass carp insulin receptor α subtype molecular marker combination covers the grass carp insulin receptor α subtype genome. The relationship between it and the growth traits of grass carp was obtained through model analysis. Moreover, the inventors also found that the body weight, body length, body height and body width of the H4 diplotype constructed using it were significantly higher than those of other genotype individuals (P<0.05), and the average plumpness of 1.59 was not too high , can be used as a candidate marker for fast-growing and high-quality grass carp, and thus can be effectively applied to molecular marker-assisted breeding of grass carp.

Description

Composition of SNP Molecular Markers of Grass Carp Insulin Receptor Alpha Subtype and Its Application technical field The invention belongs to the field of gene detection, be specifically related to grass carp insulin receptor alpha subtype SNP molecular marker combination and the same application. Background technique Grass carp (Ctenopharyngodon idellus) belongs to subfamily Leuciscinae, grass carp (Ctenopharyngodon), which is loved by consumers because of its fast growth rate and delicious meat. The annual output of grass carp has remained stable In 2016, the total output of grass carp reached 5.52 million tons worldwide. Feeding compound pellet feed is grass carp The main breeding mode of aquaculture, feed input accounts for about 70% of the total input cost, therefore, in order to obtain better economic benefits, How to effectively reduce the cost of feed has become the focus of the breeding industry. Carbohydrates belong to the cheapest energy-supplying s...

Problems solved by technology

However, when the level of sugar in the feed exceeds a certain limit, it will easily cause problems such as decreased immunity, slow growth, and increased mortality of fish. It is extremely important and also helps to reduce the cost of grass carp farming significantly
