GB 16715.2-1999

GB 16715.2-1999 specifies quality requirements, testing methods, and labeling for seeds of Chinese cabbage group vegetables, including heading cabbage and non-heading varieties. It is applied in seed production, quality inspection, and commercial seed trading within China to ensure seed purity, germination rate, and moisture content meet agricultural standards. This standard is primarily used by seed companies, agricultural regulators, and farmers for certification and procurement of high-quality cabbage seeds.
