Fig. 2From: Genetic origin and composition of a natural hybrid poplar Populus × jrtyschensis from two distantly related speciesBox plot of genetic differentiation (Φst) between each of the three species pairs based on nuclear and SSR data sets. NJ, JL and NL represent the Φ st value between P. nigra and P. × jrtyschensis, P. × jrtyschensis and P. laurifolia, P. nigra and P. laurifolia. The Φ st of each locus was estimated individually by AMOVA. Divergence between P. × jrtyschensis and parent species is lower than that between parent species as expected for a hybrid speciesBack to article page
