Reflexo da interação genótipo x ambiente sobre o melhoramento genético de feijão

Abstract: RESUMO O objetivo foi avaliar os componentes da variância fenotípica e estimar a influência da interação genótipo*ambiente no rendimento de grãos em feijão. Os componentes da variância fenotípica foram estimados pelo método da máxima verossimilhança restrita e do melhor preditor linear não viesado (REML/BLUP

“…These results were expected to happen, since grain yield is a quantitative-nature characteristic and, consequently, very environmentally influential. Similar results were reported by PEREIRA et al (2016) andROCHA et al (2017) in studies with different bean species.…”

“…The grain yield (Vf) was influenced by 25.8% due to the interaction effects (Vint). The interaction (Vint) was determined by 48.6% due to the genetic effects, in this way, the results were concordant to those obtained by Pereira et al (2015) in beans, where 59% of the phenotype was due to the G x E interaction. The influence of the environment on the interaction is due to the nature of the grain yield character, being controlled by many genes and its phenotypic expression is highly dependent on the characteristics of the growing environment (Piepho et al, 2012).…”

“…The great challenge of plant breeding is elucidating the participation of this factor in the genotypic performance in order to adjust the genetic constitutions to the environment (Vencovsky, Ramalho, & Toledo, 2012). However, the alternation of genotypes and locations in breeding cycles is often observed, especially in annual and fast-cycle species, such as beans (Pereira et al, 2016). Therefore, locations can affect the performance of certain genetic constitutions, while years may also present superior effects.…”
