摘要
欧洲和北美十分重视银杏观赏种质资源收集,保存和繁殖,欧洲有银杏观赏品种34个,美国有50个。中国有10余个,引进品种15个。中国拥有世界银杏种质资源的90%以上,银杏观赏品种研究对银杏物种起源、分类及演化;对银杏生物学、生态学及育种和栽培有重要意义。作者对银杏观赏种质资源和品种进行评述,并提出良种选育主要指标。
The collection, conservation and propagation on ornamental germplasm resources of Ginkgo were paid very attention to Europe and North America. At present, there are thirty--four Ginkgo ornamental cultivars in Europe, fifty cv. in American, and about ten cv. and introduced fifteen new cv. from Europe in China. There are more than 90 % Ginkgo germplasm resources of the world in China. It is very important that studies on Ginkgo ornamental germplasm resources to origin, classify and evolu- tion, and biology, ecology, breeding and cultivation on Ginkgo. The germplasm resources on Ginkgo ornamental ev. in the world are reviewed and made a standard on fine ornamental ev. selection of Ginkgo.
