Among them, sowing quality mainly reflects the impact of seed appearance quality on seed sowing, and is divided into physical Quality and physiological quality. The most commonly used physical quality is cleanliness, dryness, fullness, uniformity and other characteristics, such as water Physiological quality mainly reflects the vitality of seeds, especially under suitable environmental control conditions. The structural function and developmental capacity of seedlings under most conditions, that is, the ability to normally germinate and grow into plants under most conditions. The main indicators of physiological quality are germination Seed variety quality (varietal quality), also known as genetic quality (genetic quality) mainly reflects the characteristics of The genetic background characteristics and genetic background consistency characteristics of crop seeds. At present, the indicators for measuring seed variety quality include variety authenticity The health quality mainly reflects the health status of seeds, whether there are any Pathogens, such as fungi, bacteria and viruses, and animal pests, including nematodes and insects, may also be involved in physiological conditions, such as trace element deficiencies. GB/T 3543 "Inspection Procedures for Crop Seeds" is the basic standard for seed inspection methods, which consists of general principles, sampling, sowing quality, variety quality and It is composed of health quality and other parts, aiming to provide inspection basis for the quality requirements of the above three types of seeds, and is planned to be divided into the following 12 parts. --- Part 1.General. The purpose is to establish the general and overall requirements for each part of the inspection procedures for crop seeds and to govern the inspection procedures. Each part of the program. --- Part 2.Sampling. The purpose is to clarify the methods of sampling from seed batches, sub-sampling for testing and preservation of samples. program. --- Part 3.Seeding quality purity analysis. The purpose is to clarify the method for determining the net seed content in crop seed samples program. --- Part 4.Seeding quality germination test. The purpose is to clarify the test method and procedures for the germination of crop seed samples. --- Part 5.Variety quality and purity identification. The purpose is to determine the percentage of seeds of this variety in a seed sample. Methods and procedures. --- Part 6.Determination of moisture content in seeding mass. The purpose is to clarify the method and procedure for moisture content of crop seed samples. --- Part 7.Other items of inspection. The purpose is to clarify the method and procedures for seed sample health. --- Part 8.Determination of 1000-seed weight of sowing quality. The purpose is to clarify the method and procedure for determining the weight of 1000 seeds per seed sample. --- Part 9.Determination of sowing quality viability. The purpose is to clarify the method and procedure for determining the viability of seed samples. --- Part 10.Determination of seed quality vitality. The purpose is to clarify the method and procedure for determining the vitality of seed samples. --- Part 11.Variety quality and authenticity identification. The purpose is to clarify the identification methods and procedures for variety authenticity. --- Part 12.Determination of genetically modified seeds for variety quality. The purpose is to clarify the composition, genetic purity and gene authenticity of genetically modified seeds. Procedure for determination of authenticity. This document is the "purity identification" part of variety quality. This document follows international common practices and fully considers new technologies and methods. The rapid development of the industry mainly standardizes methods such as plot planting identification, DNA molecular detection and protein electrophoresis detection. Variety purity is an important indicator of variety quality, has a great impact on agricultural production, and is a quality indicator that all parties pay close attention to.

The typical degree of consistency is expressed by the percentage of seeds of this variety or the elimination value. 3.1.3 Variety purity specified value The minimum value of variety purity allowed for commercial seed sales as specified in technical specifications or standards. 3.1.4 Reject numbers The number of hybrid plants in a seed batch is accepted or eliminated based on the interests of seed producers and minimizing the risk of misjudgment. Note. Elimination values are generally used in situations where the purity requirements of the variety are high. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 3543.5-2025_English be delivered?Answer: Upon your order, we will start to translate GB/T 3543.5-2025_English as soon as possible, and keep you informed of the progress.
