Clustering of soybean genotypes via Ward- MLM and ANNs associated with mixed mo...
Teodoro, P.E.; Torres, F.E.; Corrêa, A.M.não consta número de páginas; The objectives of this study were to use mixed models to confirm the presence of genetic variability in 16 soybean genotypes, to compare clusters generated by artificial neural networks (ANNs) with those created by the Ward modified location model (MLM) technique, and to indicate parental combinations that hold promise for obtaining superior segregating populations of soybean. A fi...
Selection of common bean (Phaseolus vulgaris L.) genotypes using a genotype plu...
Corrêa, A.M.; Teodoro, P.E.; Gonçalves, M.C.; Santos, A.; Torres, F.E.não consta números de página; Recently, the genotype plus genotype x environment interaction (GGE) biplot methodology has been used to investigate genotype x environment interactions in several crop species, but has not been applied to the common bean (Phaseolus vulgaris L.) crop in Brazil. The aim of this study was to identify common bean genotypes that exhibit high grain yield and stability in the State of Ma...
Simultaneous selection for cowpea (Vigna unguiculata L.) genotypes with adaptab...
Torres, F.E.; Teodoro, P.E.; Rodrigues, E.V.; Santos, A.; Corrêa, A.M.; Ceccon, G.The aim of this study was to select erect cowpea (Vigna unguiculata L.) genotypes simultaneously for high adaptability, stability, and yield grain in Mato Grosso do Sul, Brazil using mixed models. We conducted six trials of different cowpea genotypes in 2005 and 2006 in Aquidauana, Chapadão do Sul, Dourados, and Primavera do Leste. The experimental design was randomized complete blocks with four replications an...
Artificial intelligence in the selection of common bean genotypes with high phe...
Corrêa, A.M.; Teodoro, P.E.; Gonçalves, M.C.; Barroso, L.M.A.; Nascimento, M.; Santos, A.; Torres, F.E.Artificial neural networks have been used for various purposes in plant breeding, including use in the investigation of genotype x environment interactions. The aim of this study was to use artificial neural networks in the selection of common bean genotypes with high phenotypic adaptability and stability, and to verify their consistency with the Eberhart and Russell method. Six trials were conducted using 13 g...
Identification of sorghum hybrids with high phenotypic stability using GGE bipl...
Teodoro, P.E.; Almeida Filho, J.E.; Daher, R.F.; Menezes, C.B.; Cardoso, M.J.; Godinho, V.P.C.; Torres, F.E.; Tardin, F.D.The aim of this study was to identify sorghum hybrids that have both high yield and phenotypic stability in Brazilian environments. Seven trials were conducted between February and March 2011. The experimental design was a randomized complete block with 25 treatments and three replicates. The treatments consisted of 20 simple pre-commercial hybrids and five witnesses of grain sorghum. Sorghum genotypes were ana...
Measurements of experimental precision for trials with cowpea ( Vigna unguicula...
Teodoro, P.E.; Torres, F.E.; Santos, A.D.; Corrêa, A.M.; Nascimento, M.; Barroso, L.M.A.; Ceccon, G.The aim of this study was to evaluate the suitability of statistics as experimental precision degree measures for trials with cowpea (Vigna unguiculata L. Walp.) genotypes. Cowpea genotype yields were evaluated in 29 trials conducted in Brazil between 2005 and 2012. The genotypes were evaluated with a randomized block design with four replications. Ten statistics that were estimated for each trial were compared...
Bayesian approach increases accuracy when selecting cowpea genotypes with high ...
Santos, A. dos; Barroso, L.M.A.; Teodoro, P.E.; Nascimento, M.; Torres, F.E.; Corrêa, A.M.; Sagrilo, E.; Corrêa, C.C.G.; Silva, F.A.; Ceccon, G.This study aimed to verify that a Bayesian approach could be used for the selection of upright cowpea genotypes with high adaptability and phenotypic stability, and the study also evaluated the efficiency of using informative and minimally informative a priori distributions. Six trials were conducted in randomized blocks, and the grain yield of 17 upright cowpea genotypes was assessed. To represent the minimall...
Adaptability and phenotypic stability of common bean genotypes through Bayesian...
Corrêa, A.M.; Teodoro, P.E.; Gonçalves, M.C.; Barroso, L.M.A.; Nascimento, M.; Santos, A.; Torres, F.E.This study used Bayesian inference to investigate the genotype x environment interaction in common bean grown in Mato Grosso do Sul State, and it also evaluated the efficiency of using informative and minimally informative a priori distributions. Six trials were conducted in randomized blocks, and the grain yield of 13 common bean genotypes was assessed. To represent the minimally informative a priori distribut...
