Alcance y aplicabilidad

This standard applies to the production and sale of oil crop seeds in China, specifically covering rapeseed, sunflower, peanut, sesame, and oil flax. It is mandatory for all entities involved in the breeding, production, and distribution of these specific economic crop seeds. It does not apply to fiber crop seeds or other non-oil economic crops.

Requisitos técnicos

The standard specifies the minimum quality thresholds for various categories of oil crop seeds, categorized into basic seed (原种) and qualified seed (大田用种). It defines mandatory limits for four core parameters: variety purity, cleanliness, germination rate, and moisture content. For rapeseed and sunflower, the requirements are further divided into conventional seeds, parental seeds, and hybrid seeds. Peanut seeds are classified into shelled and unshelled varieties, each with distinct purity and moisture criteria. The 2024 revision notably introduces new quality benchmarks for oil flax seeds and modifies certain parameters for rapeseed, sunflower, and peanuts compared to the 2008 version. These metrics represent the absolute minimum quality commitment required by Chinese law, serving as the primary basis for penalizing substandard seeds.

Métodos de ensayo

Compliance verification relies on standardized procedures referenced from the GB/T 3543 series. Key evaluations include variety purity testing per GB/T 3543.5, cleanliness analysis per GB/T 3543.3, germination trials per GB/T 3543.4, and moisture determination per GB/T 3543.6. Seed lot sampling must strictly follow the protocols outlined in GB/T 3543.2, while final quality judgments are executed according to the general rules specified in GB 20464.
