Table 2. Genetic diversity parameters estimated for 14 bitter manioc varieties grown in three different soil types in Manicoré, Amazonas, Brazil, and for the set of varieties in each soil type, based on 10 microsatellite loci. Number of individuals (N), mean number of alleles (Ā), number of private alleles (Ap), number of multilocus genotypes (MLGs), number of unique multilocus genotypes (uMLGs), observed (H O) and expected (H E) heterozygosities and inbreeding coefficients (f). Soil types are coded as ADE (Amazonia dark earths), FP (floodplain) and OX (Oxisols). Significant values of f * (p < 0.05) are indicated.
