Fig. 3From: The maintenance of stable yield and high genetic diversity in the agricultural heritage torreya tree systemGenetic diversity in the ancient torreya tree system. A Neighbor joining tree of different age groups in GT trees based on 20 microsatellite loci. B–D Genotypes, expected heterozygosity and allele numbers in GT and NGT trees based on 20 microsatellite loci. E, F Expected heterozygosity and allele numbers in the age groups of GT rootstocks and NGT trees based on 20 microsatellite loci. Values are mean ± SE.
