Variation analysis of seeds characters of Ginkgo cultivars

摘要

The ginkgo cultivars are highly consistent in formation, but seeds characters are various, In this paper, variation of 11 seeds characters of 44 Ginkgo cultivars was explored. The result showed variation of characters related to weight of seeds (or nuts) were large, the characters related to shape were relative stable. Many seeds characters could reflect variation of ginkgo cultivars more completely, accurately and provide reference for cultivars classification and breeding.
