遗传资源泛指已用于或可用于育种的各种野生林木和人工创造品种及其近缘植物。它包括分类学中的种、变种、变型及人工创造的品种和品系。育种的原始材料是指育种工作中实际利用和即将利用的遗传资源的一小部分。林木遗传资源是开展林木遗传研究和发展林木育种工作的物质基础,因此,应该重视这方面的开发利用工作。 Genetic resources broadly refer to the variety of wild forest and artificially created breeds and their relatives that have been used or available for breeding. It includes taxonomic species, varieties, variations and artificially created varieties and lines. The original material for breeding is a small part of the genetic resources that are actually utilized and about to be utilized in breeding. Forest genetic resources are the material basis for carrying out research on forest genetics and developing tree breeding. Therefore, we should pay attention to the exploitation and utilization in this aspect.
