Core Insights - The Chinese government has implemented a key project focused on "Forestry Germplasm Resource Cultivation and Quality Improvement" during the 14th Five-Year Plan, achieving over 70% precision in the selection of forestry varieties [1] - The project emphasizes the breeding of new tree species, particularly in arid and barren regions like the "Three North" area, resulting in the development of over 110 drought-resistant varieties [3] Group 1 - The precision of forestry variety selection has been enhanced to over 70% through advancements in breeding techniques, including gene editing and whole-genome selection [1] - A total of 67 high-quality varieties of major timber species have been developed, supporting significant ecological and forestry projects across the country [1] - The use of quality varieties in key projects, particularly in the "Three North" region, has reached 85%, with over 500,000 acres applied in national ecological and forestry engineering [3] Group 2 - The focus on breeding drought-resistant and salt-alkali tolerant varieties is crucial for challenging land types, such as saline-alkali land and arid areas, to enhance ecological stability [5] - The cultivation of these varieties aims not only to increase green coverage but also to maintain and optimize the global ecosystem [5]
