The method comprises the following specific steps: S1, selecting wheat germplasm resources of different varieties, and planting the wheat germplasm resources in different regions (under different environment treatments) in fields; s2, dividing a wheat germplasm resource planting environment into two treatments, namely normal field planting and shading treatment planting; s3, performing field investigation and recording the time days from seedling emergence to heading and from seedling emergence to maturity; and S4, summarizing, concluding and comparing the data of all varieties of wheat, and completing screening and identification of early-maturing germplasm according to a growth period. The shading treatment in the step S2 is that a shading net with the shading rate of 25% is used for shading treatment. Through planting in different regions and plots, the influence of the environment on the test result is solved. The wheat planting resources are subjected to shading treatment, so that the influence on early-maturing germplasm screening under the same soil condition and different illumination conditions is solved.

Description

Technical Field

[0001] The invention relates to the field of biological agriculture, and in particular to a method for identifying early-maturing wheat germplasm resources. Background Art

[0002] Wheat is one of the most important food crops in the world and the third largest food crop in my country. Its yield plays a vital role in my country's food security. Different growth periods can reflect the growth and development rate and stability of wheat, and are closely related to the maturity period, yield and disease resistance of wheat. They have a great impact on the planting environment, regional planning, variety screening and cultivation management measures of wheat, and are the long-term focus of breeders. Screening and identifying early-maturing wheat germplasm resources is of great significance in agricultural production. Early maturity can relatively avoid the impact of diseases and adverse climatic conditions on grain yield and maintain stable grain production. Secondly, early maturity is also conducive to the selection of varieties of re-sown crops and to improving the multiple cropping index. In areas with multiple cropping systems, the use of early-maturing varieties can alleviate seasonal conflicts. Especially in the middle and lower reaches of the Yangtze River in China and southern Xinjiang, the demand for early-maturing wheat seeds is particularly prominent. The plum rain season in the south and the sandstorm weather in Xinjiang also have new requirements for the early maturity of wheat varieties under weak light conditions.

[0003] In order to solve the above problems, the applicant proposed a method for identifying early-maturing wheat germplasm resources. Summary of the invention

[0004] The purpose of the present invention is to provide a method for identifying early-maturing wheat germplasm resources to solve the problems in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for identifying early-maturing wheat germplasm resources, the specific steps of which are as follows:

[0006] S1. Select different varieties of wheat germplasm resources and plant them in different regions (under different environmental treatments);

[0007] S2, dividing the planting environment of wheat germplasm resources into two treatments, normal field planting and shading treatment planting;

[0008] S3. Field survey records the time from seedling emergence to heading and from seedling emergence to maturity;

[0009] S4. Summarize, summarize and compare the data of all varieties of wheat, and complete the screening and identification of early-maturing germplasm according to the growth period.

[0010] Optionally, the shading treatment in step S2 is performed using a shade net with a shading rate of 25%.

[0011] Beneficial effects: 1. The influence of environment on test results was solved by planting in different regions and plots. 2. The influence of different light conditions on the selection of early-maturing germplasm under the same soil conditions was solved by shading wheat planting resources. DETAILED DESCRIPTION
