According to the Seed Law of the People's Republic of China, seeds with quality lower than the national standards or label indicators are considered inferior seeds. In order to ensure seed quality, maintain market order and protect the interests of farmers, old standards such as GB4404.1-2008 need to be updated urgently.
| Project dimensions | Old standard (GB4404.1—2008) | New standard (GB4404.1—2024) |
|---|---|---|
| Variety purity requirements | 98% (field seeds) | Increased to 99% (conventional seeds) |
| GMO authenticity detection | No clear requirements | New requirements to ensure the authenticity of transformants |
| Germination rate index | 85% (rice, corn) | Increased to 88% (corn field seed) |
Basic seed: The first to third generation bred by breeders, which must undergo strict testing to ensure that they meet the specified quality requirements.
Qualified seed: The first to third generation or hybrid bred using basic seed, which is a widely used seed type in agricultural production.
Actual case: The basic seed of a certain rice variety needs to be bred and tested for more than two years to ensure that its purity reaches 99.9% before it can be used for field planting.
This revision of the standard mainly targets the following aspects:
To ensure the effective implementation of the new standard:
This interpretation is based on GB4404.1-2024 "Grain Crop Seeds Part 1: Cereals", and aims to help relevant practitioners better understand and apply the new standards. If you have any questions, please refer to the original document or consult a professional organization.
