Capacidade combinatória de genótipos de soja sob condições de cerrado de baixa latitude

Abstract: PALAVRAS-CHAVE Glycine maxMelhoramento genético Tocantins Dialelo completo KEYWORDS Glycine max Genetic improvement Tocantins Complete diallel RESUMO: A seleção de genitores para cruzamentos é uma das etapas mais importantes em programas de melhoramento, em que a predição do potencial genético das combinações híbridas permite ao melhorista canalizar recursos humanos e financeiros em populações superiores. Nesse sentido, este trabalho buscou estimar as capacidades geral (CGC) e específica de combinação (CEC) de… Show more

“…2 populations from diallel crosses. Similar results were also obtained byZorzetto et al (2009), who verified the importance of additive gene effects in the expression of the characteristics number of seeds per plant, number of pods per plant, and weight of 100-seeds.In contrast,Colombo et al (2018) obtained a greater contribution of non-additive gene effects in the F 1 generation for the expression of number of days to flowering and maturity, and grain yield. The diverged results may be related to the population of interest, since estimates of genetic parameters are intrinsic to the target population.…”
