Fig. 4. Multiple correspondence analysis showing the association between 58 Phaseolus genotypes: 4 tepary beans (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. Three clusters indicated with circles corresponding to I: genotypes of common beans and interspecific with low rates of introgression. II interspecific congruity backcross lines with higher rates of introgression and III genotypes of P. acutifolius. Arrows indicate the position of genotypes; ICA Pijao (P. vulgaris), XAN 159 (recurrent backcross interspecific line) and G40001 (P. acutifolius).
