Inheritance of Precocity and of Agronomic Characters in Soybean
Authors: F.G. Teixeira, O.T. Hamawaki, A.P.O. Nogueira, R.L. Hamawaki, C.L. Hamawaki, T.P. Mattos, I.C. Silveira and L.A. Medeiros
Precocious soybean cultivars enable crop rotation and low pressure to the biotic and abiotic factors. This study aimed to determinate the inheritance of characters related to precocity and agronomic characters in soybean segregating population, coming from contrasting genitors to cycle. The experiment was conducted at a gre.. Read More»

In order to obtain the certificate of cultivar protection, it is necessary to prove its distinctiveness, homogeneity, and stability. Currently, there are 37 descriptors for differentiating soybeans cultivars. However, they are still not enough and, as a result, it is necessary to create, identify, and evaluate new descriptors...

Identification of soybean genotypes with high stability for the Brazilian macro-region 402 via biplot analysis
Authors: E.U. Ramos Junior, R.L. Brogin, V.P.C. Godinho, F.J.E. Botelho, F.D. Tardin and P.E. Teodoro
Biplot analysis has often been used to recommend genotypes from different crops in the presence of the genotype x environment interaction (GxE). The objective of this study was to verify the association between the AMMI and GGE biplot methods and to select soybean genotypes that simultaneously meet high grain yield and stabili.. Read More»

Stability and adaptability of soybean cultivars in Minas Gerais
Authors: I.O. Soares, A.T. Bruzi, E.V. Zambiazzi, S.R. Guilherme, M.C. Bianchi, K.B. Silva, V. Fronza and C.M. Teixeira
Genotypes x environment (G x E) interaction consists of different behavior of genotypes cultivated in different environments. This interaction occurs due to the performance variation of each genotype in different environments. To reduce the effect of the interaction in soybean crops, some studies have been reported in the lite.. Read More»

Soybean genotype analysis for cyst nematode resistance
Authors: B.C.M. Juliatti, I.F. Beloti, L.C. Pena and F.C. Juliatti
Some species of soybean cultivars have the characteristic of resistance or alteration in survival skills, and perpetuation of nematodes (female index - FI), whose process is activated when the nematode parasitism starts and the development of new resistant cultivars is primordial to the preservation of plant productivity. The .. Read More»
