Problems solved by technology

They believed that the number of bee species and sample size in the above experiment was too small, and the sample selection was not very scientific. It cannot be simply inferred that W316bp can be used as a marker of high-yielding royal jelly just because three bees with high-yielding royal jelly have it but not among the low-yielding bees. Potentially related to other biological traits of four different bee species

Embodiment 1

[0033] Example 1 A method utilizing honeybee Dop2 gene fluorescent quantitative PCR technology to identify the yield performance of royal jelly, comprising the following steps:

[0034] , bee sample collection

[0035] ① During the jelly production season, 30 colonies of bees in Zhejiang Qiandao Lake Experimental Bee Farm were organized to produce royal jelly for 5 consecutive times, and the weight of royal jelly and the amount of royal jelly received by each colony were weighed and recorded.

[0036] ②5 colonies with high royal jelly production, 5 colonies with low royal jelly production, and 4 other bee colonies whose royal jelly production was between high and low yields with a gradient trend were screened out, and a total of 14 bee colonies were selected as the investigated bee colonies. The royal jelly production range of the royal jelly high-yield bee colony and the royal jelly low-yield bee colony is that the high-yield colony produces no less than 100 grams of roya...

Embodiment 2

[0080] Example 2, the expression abundance of Dop2 gene in bees with high royal jelly yield was significantly higher than that in bees with low yield of royal jelly

[0081] By counting the royal jelly production of 30 colonies of bees in the apiary five times in a row, 5 colonies with high royal jelly production and 5 colonies with low royal jelly production were finally screened. The results show that the average yield of royal jelly in the five groups of five groups of low-yield royal jelly is 64.32g, and the average yield of royal jelly in five groups of five groups of high-yield royal jelly reaches 115.64g. The result shows F 1，40=76.3935, P=0.0001, that is, there was a significant difference in the yield of royal jelly between the high and low yield groups of royal jelly.

[0082] The expression abundance of honeybee Dop2 gene was detected by qRT-PCR technology. The expression abundance of Dop2 gene in the five colonies of bees in the high-yield royal jelly group was 4...

Abstract

The invention relates to a method for discriminating output performance of royal jelly by using a honeybee Dop2 gene fluorescent quantitative PCR technology. The method comprises steps of: acquisition of honeybee samples; extraction of head RNA of the honeybees; synthesis of the head cDNA of the honeybees; design of primers; qRT-PCR reaction system and condition; and discrimination of output performance of royal jelly. From the height of molecular biology, the invention provides a scientific and accurate fluorescent quantitative PCR method for discriminating output performance of royal jelly, aiming at the problem that production of royal jelly is critically influenced by conditions including bee colony potential, nectar source, environment and climate. In addition, the method can substantially shorten period for investigation of royal jelly production property, accelerate the speed of honeybee breeding, reduce cost of investigation of royal jelly production property and breeding cost, and mitigate working strength for field investigation of royal jelly output performance.

Description

technical field [0001] The invention relates to a method for identifying the yield performance of royal jelly by using fluorescent quantitative PCR technology, in particular to a method for using the fluorescent quantitative PCR technology of bee dopamine receptor 2 (Dop2) gene to identify the yield performance of royal jelly. Background technique [0002] my country is a big beekeeping country, and it is also a major producer of royal jelly. More than 90% of the world's royal jelly is produced in China, and royal jelly-yielding bees are a unique bee resource in my country. For a long time, my country's bee industry scientific and technological workers have been committed to the related research on the genetic breeding of bees with high royal jelly yield, in order to find the genetic markers related to the high-yield traits of royal jelly, and serve the high-yield breeding of bee royal jelly. The genetic markers related to the high yield of royal jelly were studied at the le...
