Abstract
Chinese jujube (Ziziphus jujuba Mill.) is native and popular fruit of China owing to its wider adaptability, easy management, early bearing, rich nutrition, and multiple uses.
The genetic relationships of 22 accessions that represented 6 varieties and a wild related species (Z. acidojujuba C.Y. Cheng et M.J. Liu) of Chinese jujube were analyzed using AFLP technique.
Out of 502 marker loci assessed from 17 selective primer combinations, 255 were polymorphic (50.8%). Based on the AFLP data, Dice similarity coefficients among the samples were calculated and a dendrogram was constructed using UPGMAs method.
The similarity coefficients within the varieties were found to be lesser than those among varieties which suggest the need of new classification or taxonomic criteria in the species of Z. jujube.
