Ginkgo biloba is an economically valuable tree *** species has nearly become extinct during the Quaternary,which has likely resulted in reduction of its genetic *** genetic variability is now conserved in few natural populations in China and a number of cultivars that are,however,derived from a few ancient trees,helping the species survive in China through medieval *** the recent interest in ginkgo,however,detailed knowledge of its genetic diversity,conserved in cultivated trees and cultivars,has remained *** limits efficient conservation of its diversity as well as efficient use of the existing germplasm *** we performed genotyping-by-sequencing(GBS)on 102 cultivated germplasms of ginkgo collected to explore their genetic structure,kinship,and inbreeding *** the first time in ginkgo,a genome-wide association analysis study(GWAS)was used to attempt gene mapping of seed *** results showed that most of the germplasms did not show any obvious genetic *** size of the ginkgo germplasm population expanded significantly around 1500 years ago during the Sui and Tang *** of seed cultivars based on a phylogenetic perspective does not support the current classification criteria based on ***-four candidate genes were localized after performing GWAS on the seed ***,this study reveals the genetic basis of ginkgo seed traits and provides insights into its cultivation *** findings will facilitate the conservation and utilization of the domesticated germplasms of this living fossil plant.
