Abstract In order to study the genetic diversity of nut， 59 Chinese chestnut resources from 12 provinces were used to determine the single nut weight， soluble sugar content， starch content and protein content. The investigated Chinese chestnut resources were rich in genetic diversity， which provides an important reference index for the breeding of improved varieties of Chinese chestnut.
