Abstract
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 association between methods. We found 113 articles on adaptability and stability in maize and soybean, in which 21 methods were listed. The most commonly used method was the Eberhart and Russell methodology. The Cruz, Torres, and Vencovsky along with the AMMI methods were also widely used. The number of articles using most methods decreased in the current decade, except for the GGE Biplot, MHPRVG, and Centroid methods. In studies with more than one method, the methods were more likely to be used together with the Eberhart and Russell methodology. Adaptability and stability in maize and soybean have been widely studied over the last several decades in Brazil, although the number of publications on this subject has decreased over this time period.

Summary
The genotype by environment (GE) interaction is the differential behavior of the genotypes in relation to environmental variations This may cause inconsistency in the ranking of genotypes between environments and hinder the selection and recommendation of cultivars (Elias et al, 2016). In order to minimize the negative effects of GE interaction, the studying of adaptability and stability provides important information for the selection and recommendation of cultivars (Silva and Duarte, 2006). Several statistical methods have been proposed for studying adaptability and stability. These methods can be classified according to the statistical approach adopted, which is based on analysis of variance, linear regression and multivariate analysis (Eeuwijk et al, 2016)
