“…The use of an Andean gene pool parent for introgression of resistance in Mesoamerican cultivars, such as the Carioca variety, is usually not very simple, due to the difficulty of hybridization under reproductive incompatibility (Davis & Frazier, 1964), the breakdown of epistatic interactions specific to each center of origin (Johnson & Gepts, 2002), and segregation for grain type (Bruzi et al., 2007). In this sense, the backcross method has the advantage of transferring only specific genome regions of the donor parent, with less linkage drag, and favoring the genome recovery of the recurrent parent after some backcross cycles (Lorencetti et al., 2006).…”

“…Essa probabilidade depende dos seguintes fatores: (i) número de alelos favoráveis distintos entre os genitores usados para gerar a população; (ii) contribuição relativa dos alelos desejáveis dos genitores; (iii) probabilidade de fixação dos alelos em um bloco gênico individual; e (iv) diferenças genéticas necessárias para o pesquisador poder distinguir a planta superior do restante da população (ISLEIB, 1999;LORENCETTI et al, 2006). Sendo assim, conforme foi apresentado, a população-base ideal para o melhoramento deve associar uma média alta e a maior variabilidade possível para o caráter em questão.…”
