Genetic Biodiversity of Italian Olives (Olea europaea) Germplasm Analyzed by SSR Markers

Table 1

Genetic diversity parameters estimated for the SSR loci in the 489 olive varieties. For each locus, the number of alleles detected (𝑁𝑎), the effective number of alleles (𝑁𝑒), the observed (𝐻𝑜) and expected (𝐻𝑒) heterozygosity, the fixation index (𝐹), and the frequency of null allele (𝑁𝑢) are reported.
