Table 1.

Comparison of the genetic diversity of the whole collection of Capsicum annuum and the core collection obtained with the maximization strategy algorithm. For each collection, the table provides the number of accessions, the percentage of SSR alleles represented in the collection, the mean number of alleles observed per locus, Nei’s unbiased gene diversity (H _e), observed heterozygosity (H _o) and the percentage of accessions belonging to each cluster defined by STRUCTURE v. 2.3.4 software based on SSR markers (Nicolaï et al., 2012).

Sample	Sample size	% SSR alleles	Allele number	H e	H o	Distribution in the C. annuum clusters
						Cluster 1	Cluster 2	Cluster 3	Clusters 4–6
Whole collection of C. annuum	887	100	12.57	0.59	0.035	36% (314)	21% (190)	41% (367)	2% (16)
Core collection of C. annuum	310	91	12.07	0.59	0.035	30% (93)	23.6% (73)	42.9% (133)	3.5% (11)
