Potencial De Hibridação Entre Cultivares De Feijão Comum De Diferentes Grupos Gênicos

Abstract: Devido ao isolamento geográfico decorrente da domesticação do feijoeiro, originou-se dois pools gênicos para a cultura, o andino e o mesoamericano. Sugere-se que ocorra incompatibilidade quando hibridados genótipos dos distintos grupos. Com isso, o objetivo do presente trabalho foi avaliar o potencial de hibridação artificial entre cultivares de feijão pertencentes ao grupo gênico andino e mesoamericano. Os cruzamentos foram realizados em casa de vegetação, utilizando o método de emasculação do botão floral. D… Show more

“…Among the genitors from group II, the cultivars of the Mesoamerican group IAC Alvorada, IPR Uirapuru, and BRS Esteio showed the best performance for all agromorphological traits, when subjected to water deficit. In a study of combinatorial ability among common bean genotypes, Grigolo et al [36] verified that cultivars from Mesoamerican origin presented lower floral sensitivity compared to the ones with Andean origin, resulting in higher pod growth and, consequently, better grain yield. This characteristic may explain a greater that avoids floral abortion in Mesoamerican cultivars, improving traits related to yield.…”
