Compliance overview
Scope and applicability
This standard is applicable to the production, sale, and use of legume forage seeds in China. It covers a wide range of species including Astragalus, Medicago, Trifolium, and Vicia among others. It is mandatory for manufacturers and distributors of these agricultural products to comply with the grading requirements. Similar plant species and varieties within the same genus may refer to this standard for execution.
Technical requirements
The standard specifies the technical requirements for legume forage seed quality grading, focusing on four primary parameters: purity, germination rate, other plant seed count, and moisture content. Seeds are classified into Grade 1, Grade 2, and Grade 3, with any seed failing to meet Grade 3 standards designated as sub-grade. A key concept introduced is the pure live seed value (PLS), which is calculated by multiplying purity by germination rate. If purity and germination rate fall into different grades, the PLS value is used to determine the final comprehensive quality grade. Additionally, the standard mandates that seeds containing quarantine pests as specified by national regulations shall not be graded. The standard also outlines requirements for factory inspection, packaging and labeling, and storage conditions to ensure product integrity.
Testing methods
Testing procedures are referenced from the GB/T 2930 series for forage seed testing rules. Specific methods include: Sampling according to GB/T 2930.1; Purity analysis per GB/T 2930.2; Other plant seed number determination per GB/T 2930.3; Germination test per GB/T 2930.4; and Moisture determination per GB/T 2930.8. Factory inspections must include tests for purity, germination rate, other plant seed count, and moisture.
FAQs
What products are regulated under GB 6141-2025?
GB 6141-2025 regulates legume forage seeds used for agricultural production, sale, and usage in China. This includes various species of clover, alfalfa, and vetch, among others.
Are there any updates from the previous version of GB 6141-2025?
Yes, compared to the 2008 version, this update adds 14 new species (such as Crotalaria pallida and Lespedeza cuneata), updates indicator values for purity, germination rate, and other plant seed count for several existing species, and introduces new sections for sampling, factory inspection, packaging and labeling, and storage.
How is the final quality grade of the seed determined under GB 6141-2025?
The comprehensive grade is determined by the lowest grade among the four indicators: purity, germination rate, other plant seed count, and moisture. If purity and germination rate are in different grades, the pure live seed value (PLS) replaces them to determine the final grade alongside the other two indicators.
