Comparison of efficiency of random and maximization (M) sampling strategy in S. l. cerasiforme sample (n = 143 accessions). Score, which represents allelic richness, is plotted against size of core collection. The efficiency of the M strategy is represented by a straight line and the random strategy is represented by a dashed line. A. Core collections were sampled with alleles from 20 SSR loci and were cross validated by the same alleles. B. Core collections were sampled with alleles from 20 SSR loci and were cross validated by alleles from twelve phenotypic data split in 5 classes. C. Core collections were sampled with alleles from 20 SSR markers and twelve phenotypic data and were cross validated by the same alleles.
