Right, Pre-breeding for trait introgression using GP-II and/or GP-III (Adopted from Pratap et al., 2021) 5.2 Phylogenetic relationships within the Phaseolus genus Phylogenetic studies have revealed that the common bean has undergone two independent domestication events in geographically distinct areas: Mesoamerica and the Andes. These events have led to the formation of two major gene pools, each with unique genetic characteristics (Mamidi et al., 2011; Bitocchi et al., 2013; Schmutz et al., 2014). The genetic differentiation between these gene pools is significant, with less than 10% of the
