“…Os programas brasileiros de melhoramento de soja Glycine max desde a década de 70, procuraram desenvolver genótipos de soja com período juvenil longo, adaptados às regiões de baixas latitudes, característica esta que permitiu a expansão da cultura da soja à região central do país e buscando sempre cultivares mais produtivos (PELUZIO et al, 2012;BARROS et al, 2012).…”

Estudos sobre a divergência genética e de eficiência de resposta dos genótipos a diferentes ambientes são úteis em programas de melhoramento. Neste sentido, no ano agrícola 2013/14, foram realizados dois ensaios em Palmas-TO com dezessete genótipos de soja, sendo dez cultivares e sete linhagens. O delineamento experimental utilizado, em cada ensaio, foi de blocos casualizados com dezessete tratamentos e três repetições e as características estudadas foram: número de dias para o florescimento e para a maturação, altura de planta e da inserção da primeira vagem, número de sementes por vagem, número de vagens por planta, massa de cem sementes e produtividade de grãos. A eficiência ambiental foi avaliada através da metodologia adaptada de Fischer (1983) e a divergência genética por meio de procedimentos multivariados: distância generalizada de Mahalanobis e método de agrupamento e otimização de Tocher. Os genótipos CD 2737 RR (0,67) e TMG 1180 RR (0,57) foram os mais eficientes quanto ao estímulo ambiental. O índice de eficiência ambiental foi eficaz na identificação dos genótipos apenas para os ambientes desfavoráveis. As características número de dias para o florescimento (49%) e o número de vagens por planta (26,6%) foram as que mais contribuíram para a dissimilaridade genética. Os cruzamentos mais promissores foram 5X6-3 X TMG 1180 RR; 4X5-2 X TMG 1180 RR e 5X6-1 X TMG 1180 RR.

“…Evaluation of stability by using the Annicchiarico method has been reported by several authors and in several species, such as maize (Schmildt et al 2011;Possatto Júnior et al 2017a;Silva et al 2017), canola (Lima et al 2017), and soybean (Barros et al 2012). Recommendation of phenotypes based on an analysis of stability by Annicchiarico is reliable and has results that are similar to those of other methods (Schmildt et al 2011;Barros et al 2012). On the other hand, the AMMI method has been used on onion (Oliveira et al 2016) and manioc (Morais et al 2017) populations.…”

We examined the agronomic performance and stability of strawberry cultivars in three environments, using the Annicchiarico and AMMI methods. Thirteen strawberry cultivars were evaluated (Aromas, Oso Grande, Dover, Sweet Charlie, Tudla, Festival, Camarosa, Monterey, Palomar, Portola, Camino Real, San Andreas and Albion), in the towns of Lavras-MG, Guarapuava-PR and Uberlândia-MG. The experimental design was blocks with randomly distributed treatments, with four replications and 18 plants per experimental unit. The total number of fruits (TNF) plant -1 , total mass of fruits (TMF) g plant -1 , number of commercial fruits (NCF) plant -1 and mass of commercial fruits (MCF) g plant -1 were evaluated. Variance analysis detected a significant effect for cultivar, environment, and cultivar x environment interaction for all the characteristics. The agronomic performance of the Dover cultivar stood out for TNF, TMF and NCF, while the Camarosa cultivar stood out for MCF. When we examined phenotypic stability in terms of yield in different cultivation environments, the Albion cultivar stood out for TMF, and Monterey and San Andreas for NFC.

“…The evaluation of stability by the Annicchiarico method has been used by many authors and in several species, such as soybean (Barros et al, 2012) and rice (Ramos et al, 2011). Schmildt & Cruz (2005) evaluated different methods of stability and concluded that the Annicchiarico method was the more reliable than Eberhart and Russell because of the ease of interpretation, the precision in the indication of cultivars for each type of environment and because of the fact that the method presents only one parameter of interpretation while Eberhart and Russell's method uses four parameters.…”

The expansion of wheat cultivation to new and promising regions has been an alternative to increase Brazilian production. For this purpose, the study of genotypes x environments interaction is essential for the recommendation of new cultivars. The objective of this research was to evaluate the adaptability and phenotypic stability of the grain yield of wheat genotypes grown in 10 environments in the states of São Paulo and Paraná, using Annicchiarico and AMMI methods. The experiments were composed of 20 lines and five commercial cultivars (checks), evaluated in ten environments, in randomized complete block design. The line G19 and the cultivar Ametista were stable in all environments. The G5 line showed specific adaptability to the Apucarana environment. The lines G7, G8, G18, G21 and G24 were adapted to Nova Fatima environments in the two evaluated years. Based on the results, the cultivars for a micro-region in the region of wheat can be recommended. It was verified that in the group of genotypes there is genetic variability, and that the most stability and adaptability, can be used as a source of favorable characteristics in future breeding cycles aimed at the region.
