基因组工具的开发将加强传统的树木育种技术，从而更确定和及时地恢复美国东部的重点遗产树美国板栗。目前正在基因发现、遗传标记开发、基于BAC的物理图谱构建和DNA转化技术方面做出重大努力。基于图位克隆，关联遗传学和基因工程，结合传统的和标记辅助回交育种的策略，提出了长期的遗传恢复这一标志性树种。
The development of genomic tools will enhance traditional tree breeding technologies leading to more certain and timely recovery of the American chestnut, a keystone heritage tree of the eastern United States. Major efforts are being made in gene discovery, genetic marker development, construction of a BAC-based physical map, and DNA transformation technology. A strategy of map-based cloning, association genetics, and genetic engineering, combined with traditional and marker-assisted backcross breeding is proposed for the long-term genetic restoration of this iconic tree species.
