“…Thus, the BRS Xiquexique, genotype recommended for unfavorable environments by the Eberhart and Russell (1966) method, is more stable according to the traditional method, besides obtaining above overall yield mean of testing. These results confirm those obtained by Cargnelutti Filho et al (2007, 2009, who, when comparing methods for estimating the adaptability and stability of maize genotypes, found that genotypes indicated by the traditional method have greater stability, being more suitable to unfavorable environments by the Eberhart and Russell (1966) method.…”

“…Thus, amongst the evaluated genotypes, MNC99-541F-15 proved to be the most stable, in addition to the fact that its grain yield is above the overall average of trials and it is also recommended by the Eberhart and Russell (1966) Cargnelutti Filho et al (2007, 2009) also assess the association between these methods for indicating the most productive maize genotypes.…”

Currently, cowpea growing covers three Brazilian regions, making essential the investigation of the magnitude of genotype x environment essential for choosing the best selection strategy and recommendation of cultivars. The aim of this study was to evaluate the adaptability and phenotypic stability of semi-prostate cowpea genotypes in sites from State of Mato Grosso do Sul based on different methodologies. We conducted four value of cultivation and use testing with lines and cultivars of cowpea genotypes in the years 2005 and 2006 in the municipalities of Aquidauana, Chapadão do Sul and Dourados. The experimental design was randomized complete block with 20 treatments and four replications. The grain yield data were submitted to individual and joint analysis of variance. Subsequently, data were submitted to adaptability and stability analysis by Eberhart and Russell (1966), Yates and Cochran (1938) (traditional) and Wricke (1965) methodologies. The genotypes BRS Xiquexique, TE97-304G-12, BR 17-Gurguéia and MNC99-541F-15 are the most suitable for growing in Mato Grosso do Sul by combine high yield grain, adaptability and phenotypic stability.

“…Therefore, the indication of genotypes through adaptability and stability analyses is an adequate procedure, especially when this interaction occurs with the contribution of most of the genotypes under analysis. This GxE was also found in other trial sets (Cargnelutti Filho et al, 2007, 2009.…”

“…SVmg, SVmf, and SVmd also agreed regarding their respective estimates of stability by the LB method for general (LBPg; r s = -0.97), favorable (LBPf; r s = -0.84), and unfavorable (LBPd; r s = -0.87) environments. Therefore, the genotypes with the lowest LBPg, LBPf, and LBPd scores, and with higher AN parameters by the linear regression coefficients of ER and of segmented regressions (SB, CR, and SV), are the most indicated for recommendation and also the most (Silva & Duarte, 2006;Cargnelutti Filho et al, 2009). Cargnelutti Filho et al (2009 pointed out that the high agreement of the LB and AN parameters with the average of grain yield indicates a possible inefficiency of these methods, since the recommendation of genotypes based on these parameters and the average of productivity is similar and, in this case, the effects of the GxE would not be considered.…”

-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 of determination of 80 and 90%, were

“…As expected, the regression-based methods (FWb), (ERb), and (TAb) showed high correlation estimates (ERb x FWb, TAb=1.00; TAb x FWb=1.00), because they are based on similar mathematical concepts, making its concomitant use unnecessary for adaptability studies. Duarte (2006) andCargnelutti Filho et al (2009) also found positive and significant association among adaptability parameters proposed by ER and TA methods. The parameter estimates of (FWb), (ERb), and (TAb), when compared with the estimates obtained using the other methods, showed significant correlation with the stability parameters of favorable environment group of the (LBPif) (LBPif x FWb, ERb, TAb=-0.84), (ANWif) (ANWif x FWb, ERb, TAb=0.82), (CTII) (CTII x FWb, ERb, TAb=0.71) methodology; and unfavorable environment group of the (CTIII) (CTIII x FWb, ERb, TAb=-0.66) methodology.…”

Abstract:Comparison of methods of adaptability and stability has raised interest, and there are SOME studies dealing on the subject; with that, this study aimed to estimate the correlation coefficient for adaptability and stability parameters in regions of degraded areas for grain yield, using competition experiments of soybean genotypes in the agricultural years of 2009-2010 and 2010-2011 and Wricke are associated with the highest stability and they are independent of adaptability to general, favorable, and unfavorable environment and should be used with restraint. Cultivars with high yield and adapted to favorable environments may be the best indicated alternative according to the method developed by Lin and Binns modified by Carneiro, Annicchiarico, and Centroid. The method of Eberhart and Russell may preferably be used for considering the productivity, stability, and adaptability simultaneously to general, favorable, and unfavorable environments The simultaneous use of Lin and Binns' methodologies modified by Carneiro, Annicchiarico, Centroid, and Eberhart and Russell can assist in selecting the promising genotypes for regions of degraded areas of the Amazonian "cerrado.Key words: Coefficient. Multi-environments. Glycine max. Resumo:A comparação entre metodologias de adaptabilidade e estabilidade tem levantado interesse, existindo diversos trabalhos tratando sobre o assunto, com isso, objetivou-se com este trabalho estimar o coeficiente de correlação para parâmetros de adaptabilidade e estabilidade em regiões de áreas degradadas para a produtividade de grãos, através de ensaios de competição de genótipos de soja nos anos agrícolas 2009/2010 e 2010/2011, nos municípios de Gurupi e Palmas -TO. Através do coeficiente de correlação de Spearman, foi verificada a associação entre a média e as metodologias de Plaisted e Peterson, Wricke, Annicchiarico, Finlay e Wilkinson, Eberhart e Russell, Tai, Lin e Binns modificado por Carneiro e Centróide. Os métodos de Plaisted e Peterson e Wricke, estão associados à maior estabilidade e independe da adaptabilidade a ambiente geral, favorável e desfavorável, devendo ser usados com restrição. Cultivares com alta produtividade e adaptados aos ambientes favoráveis podem ser os mais indicados pelo método de Lin e Binns modificado por Carneiro, Annicchiarico e Centróide. O método de Eberhart e Russell, por considerar simultaneamente a produtividade, a estabilidade e a adaptabilidade a ambientes geral, favorável e desfavorável, pode preferencialmente ser utilizado. A utilização simultâneas das metodologias de Lin e Binns modificado por Carneiro, Annicchiarico, Centroide e Eberhart e Russell podem auxiliar na escolha de genótipos promissores para regiões de áreas degradadas do cerrado amazônico.Palavras-chave: Coeficiente. Multiambientes. Glycine max.
