Pi nucleotide diversity, Ho observed heterozygosity, MAF minor allele frequency, Fis inbreeding coefficient. In the same type and line, the different letters indicate a significant difference at P = 0.05 level by t-test. Species contain C. tachangensis and C. gymnogyna. Altitude contains H1, H2 and H3, which are the first (> 1400 m), second (1400–1100 m), and third (< 1100 m) altitude gradients, respectively. Classes contain CR (Carbonate Rock) and SR (Silicate Rock). Areas contain I Dolomite sub-suitable area, II Dolomitic limestone suitable area, III Clastic rock most suitable area, and IV Purple clastic rock suitable area
