摘要: Abstract Universal primers were used to amplify mtDNA non-coding regions in Diospyros spp. including 6 related species and 20 genotypes of kaki Thunb. The results showed: (1) 32 universal successfully amplified either introns or intergenic A total 119 bands obtained, which 110 polymorphic. (2) Twenty three analysis genetic diversity at the level intra-specific, revealed that mitochondrial genomes had abundant variation during recombination. Chinese, Japanese PCNA separated distinctly from each other by clustering analysis. (3) Two Chinese persimmon, ‘Baogaitianshi’ ‘Eshi No.1’, have unique materials, showed they would derived same female parent according maternal inheritance genome.
