运用林木选择育种原理，从全县297株雌银杏古树中发现并选育出两个具有药用价值高，结实早、丰产稳产、抗逆性强等特点的黑银杏优良无性系──中银黑1号和中银黑2号。黑银杏种仁中总黄酮含量0．9mg／kg，叶片中总黄酮含量8.5g／kg，分别比普通银杏（梅核白果）高50％和41．7％。文中还介绍了黑银杏的优良经济性状、生物学特性和生态学习性。
Based on the principles of tree selection and breeding, two elite clones of black ginkgo with high medicinal value, early maturity, high and stable yield, strong resistance and so on were found and bred from 297 female Ginkgo biloba trees in the county-BOC Black No. 1 and Bank of China Black No. 2. The content of total flavonoids in black ginkgo seeds was 0.9 mg / kg, and the total flavonoid content in leaves was 8.5 g / kg, which was 50% and 41.7% higher than that of common ginkgo biloba.
