ABSTRACT: The aim of this study was to evaluate the experimental precision of different methods of statistical analysis for trials with large numbers of soybean genotypes, and their relationship with the number of replicates. Soybean yield data (nine trials; 324 genotypes; 46 cultivars; 278 lines; agricultural harvest of 2014/15) were used. Two of these trials were performed at the same location, side by side, forming a trial with six replicates. Each trial was analyzed by the randomized complete block, triple lattice design, and use of the Papadakis method. The selective accuracy, least significant difference, and Fasoulas differentiation index were estimated, and model assumptions were tested. The resampling method was used to study the influence of the... |

Abstract: The objective of this work was to evaluate the association between estimates of adaptability, stability, and productivity in soybean (Glycine max), and to estimate the repeatability coefficient of these associations between years. A total of 22 genotypes were evaluated in 27 environments in the 2012/2013 crop season and in 19 environments in 2013/2014. In the next crop seasons, 28 genotypes were evaluated in 26 environments, in 2014/2015, and in 25 environments in 2015/2016, totalizing 97 trials. Fourteen methods were evaluated; Spearman correlation coefficients were obtained for the parameters of stability, adaptability, and productivity; and the repeatability coefficients, as well as the minimum number of required environments for a coefficient... |

O objetivo deste trabalho foi caracterizar cultivares brasileiras de trigo, desenvolvidas em diferentes décadas, quanto à eficiência de uso de N, sob diferentes disponibilidades do nutriente. Dez cultivares de trigo, lançadas entre 1940 e 2009, foram submetidas a quatro doses de adubação nitrogenada (0, 60, 120 e 180 kg ha-1 de N), em ambiente controlado, em delineamento de blocos ao acaso, com três repetições. A produtividade de grãos aumentou em 0,54, 0,74, 0,74 e 0,82% ao ano, nas doses de 0, 60, 120 e 180 kg ha-1 de N, respectivamente. As eficiências de absorção e de utilização de N estiveram positivamente associadas à eficiência de uso do nitrogênio, com estreitamento na relação em condições de alta disponibilidade de N. As cultivares modernas são... |

Abstract: The objective of this work was to evaluate the productive performance, and the adaptability and stability parameters of modern soybean (Glycine max) cultivars in multi-environment trials, as well as to identify the ideal genotypes for eight growing environments in Brazil. A randomized complete block experimental design was carried out, with three replicates, for the evaluation of 46 soybean cultivars in eight environments, in the microregions of adaptation 102, 201, and 202, in the 2014/2015 crop season. A complex genotype x environment interaction occurred, with changes in the ranking of genotypes among locations. The NA 5909 RG, M6410IPRO, NS 5959 IPRO, NS6823RR, M5917IPRO, NS 6767 RR, and 6563RSF IPRO cultivars showed the highest mean yields.... |
