Problems solved by technology

Long-term use of these chemicals, if used improperly, will inevitably cause pests to develop resistance to chemicals, pollute the environment, and cause harm to human health and other problems
In order to overcome the shortcomings of chemical pesticide resistance and reduce chemical pesticide pollution, it is imperative to formulate reasonable and effective comprehensive control measures for pear gall midge

Embodiment Construction

[0058] The following complete specific examples will further illustrate the present invention:

[0059] A method for identification of pear germplasm resistant to pear gall midge, the steps are:

[0060] 1. Investigation time

[0061] When the ambient temperature in the field reached 30°C, two weeks after the peak emergence of the second-generation pear gall midge adults, that is, on June 15, the branch damage rate and leaf damage rate of pear varieties were investigated.

[0062] 2. Survey method

[0063] (1) Survey on the damage rate of new pear trees

[0064] Six trees were randomly surveyed for each germplasm, and each tree was surveyed in five directions: east, west, south, north and middle, and 10 annual shoots were randomly surveyed in each direction. The new shoots of pear trees with 1 or more leaves are defined as the damaged shoots by pear gall mosquitoes.

[0065]Calculate the new slightly damaged rate of a single pear tree according to the number of newly damag...

Abstract

The invention discloses a method for identification of pear germplasm resistance to pear gall midge, which comprises the following steps: (1) investigation time, mainly determining the investigation time for the identification of pear gall midge resistance; (2) investigation method, mainly determining pear gall midge The investigation method of the damage rate of new mosquitoes and leaves; (3) the calculation of the comprehensive damage rate of pear germplasm, which mainly uses the damage rate of pear gall midges and the damage rate of leaves to calculate the comprehensive damage rate of pear germplasm; (4) pear species Quality-resistant pear gall mosquito identification and grading standards. The treatment of the invention can effectively solve the technical problem of rapid identification of pear species resistance to pear gall midge in pear scientific research, breeding and production.

Description

technical field [0001] The invention belongs to the field of fruit tree research, and relates to a method for identification of pear germplasm resistance to pear gall midge. The method can effectively solve the problem of quick identification of pear species resistance to pear gall midge in scientific research, breeding and production of pears. This method is suitable for scientific research units, companies and individuals engaged in pear scientific research, breeding and production. Background technique [0002] Pear belongs to Rosaceae (Rosaceae) Apple subfamily (Maloideae) Pyrus (Pyrus) plant, is the deciduous fruit tree of Qiaoben, is one of three major cultivated fruit trees in my country, and also occupies a pivotal position in the world. According to statistics from the Ministry of Agriculture and Rural Affairs of the People's Republic of China, in 2016, my country's pear planting area was 1,113,000 hectares, with an output of 18,704,400 tons, ranking first in the wo...
