Repeatability of associations between analytical methods of adaptability, stability, and productivity in soybean PAB
Woyann,Leomar Guilherme; Milioli,Anderson Simionato; Bozi,Antonio Henrique; Dalló,Samuel Cristian; Matei,Gilvani; Storck,Lindolfo; Benin,Giovani.
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...

Adaptation patterns of winter wheat cultivars in agro-ecological regions Scientia Agricola
Studnicki,Marcin; Derejko,Adriana; Wójcik-Gront,Elżbieta; Kosma,Michał.
ABSTRACT: Multi-environment trials are commonly used to assess cultivar adaptation patterns under different environmental conditions and to help make effective cultivar recommendations for growers. An example of a multi-environment trial system used for cultivar recommendations is the Polish Post-registration Variety Testing System. A common approach in cultivar recommendations is to evaluate the adaptability of cultivars across, or for, specific trial locations. However, the locations of the trials and the fields where a farmer will grow a crop are hardly ever in the same place. Therefore, it would be better to group the trial locations into regions and give recommendations for the whole region. The aim of this study is to evaluate the grain yield...

Half a century of studying adaptability and stability in maize and soybean in Brazil Scientia Agricola
Rezende,Wender Santos; Cruz,Cosme Damião; Borém,Aluízio; Rosado,Renato Domiciano Silva.
ABSTRACT: The study of adaptability and stability underlies the cultivar recommendation process for all crops. There is a considerable number of statistical methods available for this purpose, but little is known about their actual adoption by the Brazilian scientific community. The objective of this study was to carry out a systematic review of the scientific literature on the adaptability and stability methods used in maize and soybean in Brazil from scientific articles published between 1970 and 2017 in Brazilian journals. Article searches were carried out in journals indexed through the SciELO database. The articles were classified according to the year of publication and the adaptability and stability methods used. We also evaluated the pattern of...
