Resumo: | The objective of this work was to estimate genotypic and phenotypic parameters associated with early maturity, and to select soybean (Glycine max) progenies that are high yielding and early maturing. F3:4 and F3:5 progenies were evaluated during the 2016/2017 and 2017/2018 crop years in five environments. Data on days to full maturity, days to flowering, and grain yield were collected and analyzed using the mixed model approach. Genotypic and phenotypic parameters, expected and achieved selection gains, and correlated responses were estimated. The components genetic variation and genotype x environment interaction were significant. Heritability fluctuated from 50.14%, for grain yield, to 90.37%, for full maturity. The achieved genetic gain for full maturity ranged from -0.17 to -2.57%. A positive correlation was observed among the three evaluated traits. The selection of 5.0% of the earliest-maturing soybean progenies would reduce mean grain yield by about 5.02%, but also reduce time to reach full maturity from 125 to 119 days, in detriment of 210.5 kg ha-1 potential yield. Five progenies reached full maturity up to 120 days. Progeny 51 overperformed the more productive parent (NK 7074 RR), with a grain yield of 4,975 kg ha-1 and 128 days to full maturity. |

Progênies F3:4 e F3:5 foram avaliadas durante os anos agrícolas de 2016/2017 e 2017/2018, em cinco ambientes. Dados de dias para o florescimento, dias para maturação plena e produtividade de grãos foram coletados e analisados via abordagem de modelos mistos. Foram estimados parâmetros genéticos e fenotípicos, ganhos esperados e realizados com a seleção, e respostas correlacionadas. Os componentes variância genética e interação genótipos por ambientes foram significativos. A herdabilidade oscilou de 50,14%, para produtividade, a 90.37%, para maturação plena. O ganho realizado para maturação plena variou de -0.17 a -2.57%. Observou-se correlação positiva entre os três caracteres avaliados. A seleção de 5,0% das progênies mais precoces reduziria a média produtiva em cerca de 5,02%, mas também reduziria o tempo até maturação plena de 125 para 119 dias, em detrimento de 210,5 kg ha-1 do potencial produtivo. Cinco progênies apresentaram maturação plena até 120 dias. A progênie 51 superou o parental mais produtivo (NK 7074 RR), com rendimento de grãos de 4.975 kg ha-1 e 128 dias até maturação plena.Embrapa Secretaria de Pesquisa e Desenvolvimento, Pesquisa Agropecuária Brasileira2022-06-30T19:01:10Z2022-06-30T19:01:10Z2022info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, E.
