“…According to Yokomizo & Santos (2018), the height of the soybean plant, at the point of harvest, must be at least 0.50 m to allow an adequate mechanized harvest, with less losses; with an upper limit of 0.76 m. For Silva et al (2010), the ideal height of the soybean plant is 0.65 m. In the present study, at the DEC2 and DEC3 periods (December sowing and its environments), many of the genotypes showed main stem length lower than 0.50 m, which can be an aggravating factor in addition to adverse environmental conditions, resulting in even lower grain yield.…”

“…The procedures adopted to circumvent and minimize the magnitude of the interaction is the recommendation of cultivars with wide adaptability and high phenotypic stability (Barros et al, 2010). Therefore, studies on G × E interaction are of great importance, as they provide information about the behavior of each genotype in the face of environmental variations (Yokomizo & Santos, 2018;Barros, 2015).…”

“…These analyzes can help to identify genotypes with high yield potential, well adapted and stable, for the purpose of recommending cultivars, or group of cultivars, for multiple or specific environments (Cruz et al, 2012;Yokomizo & Santos, 2018).…”

For the plant breeding, developing a single soybean cultivar that is adapted and stable to multiple production environments has been a major challenge. Therefore, integrating the individual analysis of cultivars to their average response when gathered in groups of relative maturity can be a smart alternative to minimize risks and maximize soybean productivity. Nine soybean cultivars were grouped into four distinct groups as to their relative maturity (from 4.8 to 6.4), and tested in three sowing times (September, October and December) and three growing seasons (2016/17, 2017/18 and 2018/19) as to their yield performance, adaptability and stability in southwest Paraná, Brazil, latitude 25º41'52 "S, longitude 53º03'94" We, altitude of 509 meters. Performance was evaluated by grouping means, using Scott Knott. For the adaptability and stability analysis, AMMI (Additive Main effect and Multiplicative Interaction), GGE Biplot and Centroid methods were used. The NS 5909 IPRO® and NS 6909 IPRO® cultivars, both close to GMR 6.0, presented superior average performance in most of the evaluated production environments, and the earliest cultivars, with GMR less than 5.4, were the ones that produced less, in general, in different environments. Specific adaptations stood out from the general broad adaptation for the evaluated cultivars. The adaptability of the genotypes was not accompanied by high stability, which contributes to the reduction of the average productivity of the cultivars when exposed to different environments.
