Fig. 3. Dendrogram showing the association between 58 Phaseolus genotypes: 4 tepary bean (P. acutifolius), 2 common bean (P. vulgaris), 14 recurrent backcross interspecific lines (SEL, VAX, and XAN) or cultivars (Tara, Jules) and 38 congruity backcross (CBC) interspecific hybrids. UPGMA analysis was based on genetic similarities calculated with the Dice coefficient (Nei and Li, 1979). The values above key nodes denote 95% confidence intervals for those nodes, as revealed by a bootstrap analysis.
