“…vinifera accessions that are maintained at the germplasm bank of El Encín (Alcalá de Henares, Madrid, Spain; http://www.madrid.org/ coleccionvidencin/). The selection of the accessions was carried out using the genotypic information of the 26 SSRs included in multiplex PCRs Mx01 and Mx02 (Table 1), referred to as Bcontrol loci^from now on, and the maximization strategy implemented in the software MStrat v4.1 (Gouesnard 2001). Furthermore, the validation collection includes 14 known trio pedigrees (two progenitors and one progeny, Online Resource 1: Table S1) involving 31 among the 207 accessions.tgroup…”

“…The core collection of 348 tomato cultivars was constructed by the MSTRAT software version 4.1 (Gouesnard et al, 2001). Two algorithms were used for analysis, namely maximization (M) strategy and random sampling.…”

“…The standard M strategy described by Schoen and Brown (1993) was employed using the MSTRAT software (Gouesnard et al, 2001). Four main subsets of different sizes were assayed, including 64 (5.0% of the entire set), 128 (10.0%), 256 (15.0%), and 384 (20.0%) accessions.…”

“…In fact, the M strategy (Schoen and Brown, 1993) can effectively select the accessions of a core collection and minimize the probability that any existing allele in the entire collection is missing from the core collection. The implementation of this strategy in the MSTRAT program (Gouesnard et al, 2001) allows the alleles to be selected in an interactive manner, achieving high diversity by the allelic richness criteria and large sum-of-squares values of the variables analyzed. In contrast, the PowerCore algorithm utilizes a heuristic search based on the A* search concept, which is defined by the evaluation criteria of variable coverage (the ratio between the values in the core collection and those in the entire collection and the average of all variables) (Kim et al, 2007).…”
