Abstract: Objetivou-se estudar o comportamento de cultivares de soja na região Centro Norte Paulista, na safra 2016/17. O experimento foi instalado no Polo Centro Norte -APTA Regional, vinculado a Secretaria de Agricultura e Abastecimento. O delineamento experimental foi o de blocos casualizados, com três repetições, sendo testadas 30 cultivares de soja, 25 com tecnologia Intacta RR 2 PRO e 5 com tecnologia RR1. As parcelas úteis constituíram-se de 2 linhas de cinco metros de comprimento, com espaçamento entrelinhas de … Show more

The objective of this study was to evaluate the performance of soybean cultivars through their correlations and canonical variables in a tropical environment. The study was conducted in the municipality of Mineiros, GO, Brazil. The soil was classified as Quartzarenic Neosol (Entisol). The experimental design used was in randomized blocks consisting of 10 soybean cultivars (Bônus, Desafio, Flecha, Foco, ICS7019, M5917, M7110, Power, ST721 and ST797) in four replications. Before planting, pre-planting desiccation was performed. The fertilizer used was 450 kg ha-1 of fertilizer 05-25-15 applied in the furrow and in a single dose next to the seeding. During the conduct of the experiment, pest control was carried out respecting good practices and integrated management. At the end of the cycle of each cultivar, 10 plants were collected at random and then the agronomic attributes were taken. The data obtained were submitted to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Univariate and multivariate models were used. The analyzes were performed on the Rbio and R interface, in addition to the Software Genes. According to the summary of analysis of variance, it was observed that all cultivars differed for all characteristics. It was concluded that the soybean cultivars Flecha and M5917 presented the highest yields among the others in a tropical environment; the cultivars differed, showing a strong correlation between the number of grains per plant and yield, with the other variables analyzed; the univariate and multivariate tools were efficient and complementary in data analysis.

The soybean crop presents several cultivars available. The performance of each cultivar in the field is associated with its genetic characteristics and the interaction of these with environment. Specific recommendations according to environment are made soybean cultivars release based on adaptability and stability analyzes. This research evaluated twelve soybean cultivars in the northern region of Paraná State Brazil, in order to recommend the most suitable and stable cultivar. The experiment was designed in complete randomized blocks four sites: Maringá, Floresta, Cambé and Apucarana, with four replications, in 2017/2018 growing season. Totaling 48 experimental units per site, that is, a total of 192 in the experiment. The variables evaluated were: one thousand grain mass, productivity, hectoliter weight, number of pods per plant and number of grains per plant. The cultivars were evaluated for adaptability and stability by the methodologies proposed by Lin and Binns (1988) and a bi-segmented regression method according to Cruz et al. (1989). The results indicated that the selection was more reliable when the two methodologies were used, due to their correlation coefficients. Soybean cultivar 3 presented promising behavior in regions studied.
