Scope
This document establishes the procedures for the production of cotton seed varieties, stipulates the basic requirements for cotton seed variety production, the three-field method of production, the two-field method of production, the self-crossing hybridization method of production, the direct reproduction method of breeder's seeds, and the technical requirements for the quality, authenticity, and purity identification of seed varieties, as well as seed storage. It also describes quality traceability methods such as process records. This document is applicable to the production of cotton seed varieties (including hybrid cotton parent seeds).
