The improved seed multiplication system is a crucial link in the production of crop seeds, bearing on seed quality and yield. Xinjiang Hongtai Seed Industry adheres to the three-nursery system for breeder seed production, which consists of the plant row nursery, plant line nursery and breeder seed nursery — the foundation of improved seed multiplication. These three nurseries are established at scientific research and breeding bases to ensure the source selection of superior varieties. Improved seed multiplication is carried out at the company’s own 30,000-mu improved seed multiplication base and a 20,000-mu contiguous cooperative multiplication base, providing an abundant supply of high-quality seeds for production.
In the production process, a quality control system is established covering the entire process from sowing to harvesting. Roguing and elimination of inferior plants are conducted during the seedling, bud and boll stages to ensure varietal purity throughout the growth cycle. For harvesting, balers are adopted for cotton picking, and the process follows standardized steps: dedicated personnel clean the cotton pickers, each bale is labeled with detailed variety and production information, seeds of different varieties are transported separately, and ginning is carried out by grade, stack and variety. These measures ensure the orderly and standardized handling of seeds from the field to the processing workshop, thus guaranteeing the quality and purity of the harvested seeds. The improved seed multiplication system effectively safeguards seed quality, boosts agricultural production efficiency and drives the development of agricultural modernization.
