Comparison of methods for estimates of molecular genetic diversity in genus Croton: influence of coefficients, clustering strategies and data projection

M. M. Scaldaferri, Freitas, J. S., Vieira, J. G. P., Gonçalves, Z. S., Souza, A. M., and Cerqueira-Silva, C. B. M., Comparison of methods for estimates of molecular genetic diversity in genus Croton: influence of coefficients, clustering strategies and data projection, vol. 13. pp. 5566-5573, 2014.

We investigated 10 similarity (and disimilarity) coefficients in a set of 40 wild genotypes of Croton linearifolius subjected to analyses using hierarchical grouping methods, grouping methods by optimization and data projection in two-dimensional space. Genotypes were characterized by analyzing DNA polymorphism with the use of 15 ISSR and 12 RAPD markers. The distance measurements were compared by the Spearman correlation test, projection in two-dimensional space and grouping efficiency evaluation.
