Implications of predictable and unpredictable environmental factors in common bean VCU trials in Minas Gerais

“…Significant differences between the lines are expected, above all under conditions of biotic and abiotic stresses different from the conditions in which they were selected. The implications of the place of origin in which the common bean lines were selected on the magnitude of the lines x environments interaction were studied by Silva et al (2011). The authors concluded that the location of origin does not influence the stability of the lines when their environmental conditions are similar to those of the growing location, but it interferes in their performance when the environmental conditions are very different, which coincides with what was mentioned above.…”

“…The genotypes x environments interaction has been studied a great deal in the common bean crop (Silva et al 2011, Torga et al 2013. The lines x locations interaction was the most expressive, confirming the need to undertake evaluations in the greatest number of locations possible.…”

“…The locations of the experiments comprise from four (VCU 2010/2012) to six mesoregions (VCU 2002(VCU /2004 and differ not only in soil fertility, but also in management and climate conditions. Studies carried out in other conditions using crop seasons, locations, and years also showed that the location source of variation was that which most contributed to total variation (Ramalho et al 1998, Silva et al 2011). …”

“…If there is genetic variation among the lines, associated with the wide environmental variation already mentioned, the genotypes x environments interaction is expressive. Studies undertaken in Minas Gerais highlight this fact (Ramalho et al 1998, Silva et al 2011.…”

“…This effect of the environment on the performance of lines/cultivars of common bean is widely known (Pereira et al 2010, Silva et al 2011, Torga et al 2013). If there is genetic variation among the lines, associated with the wide environmental variation already mentioned, the genotypes x environments interaction is expressive.…”
