1. Camellia oleifera germplasm resource collection, conservation, evaluation and elite variety breeding. A 517-mu germplasm resource bank was established, and over 1,300 copies of Camellia oleifera germplasm resources were extensively collected and conserved across the entire natural distribution range of the species. By comprehensively applying conventional observation, physiological and biochemical analysis, and biotechnological methods, an evaluation system was established. Eighteen superior Camellia oleifera varieties were applied for and passed the national-level approval. The hybridization and mutagenesis techniques for Camellia oleifera were optimized: over 600 hybrid progenies, more than 2,000 radiation breeding materials, 18 space-bred progeny plants, and 13 new varieties including dwarf-crown and high-yield cultivars were created, laying a solid foundation for subsequent elite variety breeding.
2. Research on key technologies for Camellia oleifera elite seedling propagation and technological integration and innovation. The seedling rootstock grafting technology and light-medium substrate container seedling cultivation technology were optimized. The technological achievements of Camellia oleifera elite seedling propagation were integrated and applied, and Camellia oleifera scion orchards and standardized nursery demonstration plots were established. Technical standards and systems for quality control of Camellia oleifera elite seedlings were formulated, reducing production costs by 16.8%.
3. Regionalization test of Camellia oleifera elite varieties and research on suitable variety allocation combinations. Fifteen national-level elite varieties were selected for regionalization tests. Through adaptability evaluation of the elite varieties, combined with the determination of Camellia oleifera pollen viability and anther affinity, suitable and optimal "Ganwu" series Camellia oleifera variety allocation combinations for each major Camellia oleifera-producing area in Jiangxi Province were screened out.
4. Research on key technologies for high-efficiency cultivation of Camellia oleifera elite varieties and technological integration and innovation. The physicochemical properties and soil fertility of Camellia oleifera forests in Jiangxi Province were systematically investigated and comprehensively evaluated, and the main soil nutrient limiting factors for Camellia oleifera forests were proposed. Special bio-organic fertilizer for Camellia oleifera was developed. Overall regulation technical models for the optimal stand structure and tree structure of Camellia oleifera under different site conditions were proposed. One technical standard for Camellia oleifera pruning and shaping was formulated. Research and technological integration were conducted on labor-saving ecological cultivation technology, auxin regulation technology, composite management technology, etc.
5. Application, demonstration and promotion of key industrial technologies for Camellia oleifera elite varieties. Through the implementation of the project, demonstration bases for key industrial technologies including Camellia oleifera elite seedling propagation technology and elite cultivation technology were extensively constructed. Combined with technical training and guidance, the planting of elite Camellia oleifera varieties was promoted.

In total, this project obtained 8 technical achievement appraisals. A 517-mu Camellia oleifera germplasm gene bank was established, 18 elite varieties were bred, and over 2,600 new germplasm materials were created. One local standard was formulated, 5 patents were authorized, 50 academic papers and 5 monographs were published, 2 graduate students were trained, 61,000 mu of demonstration forests were established, and a planting area of 1.5 million mu was promoted. The research results are at the leading level both domestically and internationally.
