“…After analysis of the genetic structure using both SSRs and SNPs and phaseolin type, the accessions were almost completely grouped into two main groups, Mesoamerican (A) and Andean (B), and further analysis separated the Andean into two subgroups (B1 and B2). These results confirm that Croatian common bean landraces originate from both centres of origin, Mesoamerican, and Andean, which agrees with numerous studies done in Europe [21,[32][33][34][35] and the classification into three clusters is congruent with the results of Raggi et al, Leitão et al,and Caproni et al [13,[36][37][38].…”

Landraces represent valuable genetic resources for breeding programmes to produce high-yielding varieties adapted to stressful environmental conditions. Although the common bean (Phaseolus vulgaris L.) is an economically important food legume for direct human consumption worldwide, common bean production in Croatia is based almost exclusively on landraces and there is no common bean breeding program. Information on phaseolin type and results of population structure and genetic diversity obtained by analysis of SSR and SNP markers, in combination with the morphological characterization of 174 accessions of 10 common bean landraces (morphotypes), enabled thorough classification of accessions. The accessions were classified into phaseolin type H1 (“S”) of Mesoamerican origin and phaseolin types H2 (“H” or “C”) and H3 (“T”) of Andean origin. By applying distance- and model-based clustering methods to SSR markers, the accessions were classified into two clusters at K = 2 separating the accessions according to the centres of origin, while at K = 3, the accessions of Andean origin were further classified into two clusters of accessions that differed in phaseolin type (H2 and H3). Using SNP markers, model-based analysis of population structure was performed, the results of which were consistent with those of SSR markers. In addition, 122 accessions were assigned to 14 newly formed true-type morphogenetic groups derived from three different domestication events: (1) Mesoamerican (H1A) (“Biser”, “Kukuruzar”, “Tetovac”, “Trešnjevac”), (2) Andean—indeterminate type (H2B1) (“Dan noć”, “Sivi”, “Puter”, ”Sivi prošarani”, “Trešnjevac”) and (3) Andean—determinate type (H3B2) (“Bijeli”, “Dan noć”, “Puter”, “Trešnjevac”, “Zelenčec”). The rest of the accessions could represent putative hybrids between morphogenetic groups. The differences between the true-type groups of accessions were further analysed based on nine quantitative traits, and the subsets of traits that best distinguish among centres of origin (A: Mesoamerican, B: Andean) and genetic groups (H1A, H2B1, H3B2) were proposed.

“…The molecular weight for Phaseolin zone in the present study ranged from 42 kDa to 49 kDa (Fig. 3), which agrees with the findings reported by Madakbas et al [15] and Tomlekova et al [24]. This zone is used to determine the grouping of the accessions among the two centres of origins -Mesoamerican and Andean -, which are considered to be the primary centres of origin for common bean [11,12].…”

“…Studying the diversity in common bean is useful to generate information that can be used in crop improvement and genebank management. Genetic diversity in common bean has been carried out using morphological markers [6], isozymes, seed proteins [3,24], and various types of molecular markers [1,2,10,18].…”

The genetic diversity of common bean accessions were assessed using seed storage protein markers. At regional level, accessions from the two major growing regions showed the highest level of gene diversity (H = 0.322, I = 0.485, and H = 0.312, I = 0.473), which can be exploited for the future improvement of the crop. Based on phaseolin, the major storage protein in common bean, the majority of the accessions (86%) were grouped under Mesoamerican gene pool. Seed proteins were also used to differentiate various Phaseolus species, indicating the usefulness of seed storage proteins in species identification in this genus.

“…The proteinograms of the total seed storage proteins include the fractions corresponding to the phaseolin types, which identification was described in Tomlekova (1999) and Tomlekova et al (2009). No difference in phaseolin type was observed from single ripe seeds belonging to each Bulgarian accession except few cases within the breeding lines and varieties.…”

“…Various data confirming variability can be collected at phenotypic level of the plant, as well as at various protein and nucleotide levels (electrophoresis of storage proteins and/or enzymes, total DNA restriction profile, chloroplast DNA and/or mitochondrial DNA, DNA sequencing) (Singh, 1991;Fofana et al, 2001;Tomlekova et al, 2009). Regarding the choice of marker used (morphological and/or molecular), there are ongoing disputes (Hills, 1987;Moritz et al, 1990;Donoghue et al, 1992;CIAT Report Information, 1990b).…”
