The calculated correlation value was not significant, for 10.000 permutations (r = 0.07, p = 0.099).
According to Emygdio et al. (2003), the lack of correspondence between morphological characteristics and similarity coefficients may be attributed to the pressure of artificial selection to which the accessions are submitted, by breeding programs or by the growers themselves.
Vera et al. (1999) propose that biochemical and molecular markers have no direct effect on the plant phenotype and, are, therefore, not directly affected by selective pressure.
