Zixing Hunan Ginkgo is an important distribution area. The city ginkgo germplasm resources distribution, growth characteristics, economic traits such as systematic investigation. The result showed that the ginkgo germplasm in this city is rich in resources, has a wide range of distribution, good seed performance, and a large seed kernel, forming a large fruit characteristic of the geographical ecology of Nanling mountain ginkgo.
