Abstract:

The contents of starch, fat, protein, macro-and micro-elements of Ginkgo nuts collected from 42 trees located at 13 original regions in 9 provinces were determined. The results showed that differences among regions were higher than those among individuals within region, although the variation level for all the compositions and mineral elements were lower. Therefore, at present selection and application of high-yielding genotypes was a proper strategy to genetic improvement of Ginkgo biloba. Because increase of nut yield through individual selection within population will be achieved more easily and quickly than that for nut quality improvement in a short time.

Key words: Ginkgo biloba, Nutrient substance, Mineral element, Genetic variation
