Compliance overview
Scope and applicability
This standard specifies the quality requirements, testing methods, and packaging rules for sugar beet seeds (Beta vulgaris var. saccharifera) produced and sold within China. It applies to various seed types, including diploid, triploid, and polyploid varieties, covering both monogerm and multigerm seeds. Compliance with GB 19176-2010 is mandatory for all domestic and imported sugar beet seed manufacturers operating in the Chinese market.
Technical requirements
The standard categorizes sugar beet seeds into multigerm and monogerm types, further classifying them as basic seed and certified seed for field use. It establishes minimum threshold limits for critical quality parameters such as germination rate, purity percentage, and moisture content. For processed seeds, specific requirements are set for polished seeds, pelleted seeds, and coated seeds. The standard dictates acceptable ranges for seed diameter (particle size) and mandates strict limits on the triploid rate for male-sterile polyploid varieties to ensure genetic purity. Packaging regulations require that pelleted seeds be sold in standard units of 100,000 seeds, with strict mass distribution requirements for specified particle sizes. All packaged seeds must bear compliant labels as specified in the referenced standard GB 20464. Transportation and storage conditions must prevent contamination, moisture, and pest damage.
Testing methods
Compliance verification involves several standardized testing procedures outlined in the normative appendices. Purity analysis is conducted using specific sieving methods to separate pure seeds from other matter. The germination test utilizes a pleated paper method under controlled temperature and light conditions to evaluate normal seedling development. Additionally, the triploid rate is determined through an acetic orcein staining method to count chromosomes in root tip cells, while seed diameter and moisture content are measured using dedicated sieving and drying protocols.
FAQs
