“…Sci., Bom Jesus, v.9, n.2, p.226-234, Apr./Jun. 2018 between genotype and environment (G x E), which makes the selection or recommendation of genotypes for cultivation in different environments difficult (Batista et al, 2015;Marques et al, 2011). Therefore, to enhance the ability to identify superior genotypes and study the G x E interaction, it is necessary to evaluate genotypes in different environments to minimize the effect of environment on the expression of the phenotype (Sousa et al, 2015;Malosetti et al, 2013;Meotti et al, 2012).…”

“…One of the alternatives to mitigate the influence of the G x E interaction is the recommendation of genotypes with wide adaptability and good stability (Barros et al, 2010). In this context, various methods can be used to evaluate the performance of soybean genotypes and their interaction with the environment aiming at direct selection of the most productive, adapted and stable genotypes for the cultivation in regions (Batista et al, 2015).…”

The objective of the present study was to evaluate the grain yield and the phenotypic adaptability and stability of soybean genotypes in different Cerrado environments of Piauí, Brazil, to provide indications for cultivation in the region. Therefore, we evaluated 23 soybean genotypes and three checks in three different site (Bom Jesus-PI, Monte Alegre-PI and Currais-PI) and environments (crop year 2010/11, 2011/12 and 2012/13). Experiments were carried out in a randomized complete block design with four replications. The behavior for the average grain yield of genotypes within and among environments was verified using the Scott Knott’s method of clustering of means (P <0.05). For the study of adaptability and stability, the methods of analysis of Eberhart and Russell and AMMI were used. Genotypes had the best performance of genetic potential in 2010/11 crop year. The best group in Bom Jesus-PI consisted of 16 genotypes and had an average grain yield higher than 3181.61 kg ha-1, what is well above the global average grain yield (2108.26 kg ha-1). G5 and G9 genotypes were the ones with greater adaptability and stability in the three environments with high average grain yield (2362.5 kg ha-1). Therefore, the identification of genotypes presenting such behavior is important for recommending cultivation in the studied environments or in similar areas. It was possible to identify genotypes that have high grain yield and that are stable and adapted for cultivation in the Cerrado at Piauí state.

“…Soybean breeding programs in Brazil aim at mainly increasing oil and protein content and grain yield in order to ensure competitiveness in the world market (Batista et al, 2015). This has been achieved through continuous genetic improvement which has contributed to the development of soybean cultivars with high yield and adapted to the different environments of Brazilian (Lima et al, 2008).…”

“…In the literature, some of the studies already carried out, comparing both, have demonstrated differences in agronomic performance (Fonseca et al, 2013;Lima et al, 2008;Lima et al, 2015). The soybean agronomic performance is greatly influenced by the interaction genotype x environment, which makes difficult the identification of adapted and stable genotypes for the different growing regions (Batista et al, 2015;Branquinho et al, 2014). So, to recommend new cultivars, regional studies aimed at minimizing the environmental effects of developing cultivars are always needed (Azevedo et al, 2015;Gomez et al, 2014).…”

The aim of this study was to compare the agronomic performance of RR soybean genotypes with conventional soybean genotypes derived from two-way crosses and evaluate through path analysis the influence of important traits for culture on the grain yield (GY) in the Northwestern of São Paulo, Brazil. It was used the randomized block design with three replications. Among the analyzed RR genotypes, three genotypes has high GY, with average values over 4575.5 kg ha-1 , while among the conventional, ten genotypes, and the check Conquista showed superiority for GY, with average values over 3511.4 Kg ha-1. In general, the most productive RR soybean genotypes showed higher values when compared with conventional genotypes with higher yield. However, conventional soybean showed a higher number of superior genotypes with similar behavior when compared to the RR soybean. For the group of RR soybean genotypes, all agronomic traits, except one hundred seed weight (HSW), correlated positively with GY. For the group of conventional soybean genotypes, there was no significant correlation between GY and all agronomic traits analyzed. The genotypic correlation and path analysis indicate the plant height at flowering (PHF) and plant height at maturity (PHM) as the most favorable and direct effect on GY.
