Recent studies have shown the need to identify new potential additional descriptors for the soybean culture to contribute to cultivars differentiation. Thus, the objective of this study was to estimate generic parameters and analyze characters in the soybean plants in phenotypical phase, during two evaluation periods. The study analyzed 28 genotypes under greenhouse conditions, during two evaluation periods (October and December, 2017), in two stages of development (V2 and V3), regarding hypocotyl and epicotyl length and plant height. Experimental units (an average of two plants) were displayed in randomized blocks with four replicates. An individual and joint analysis of variance were conducted, and coefficients of experimental variation and genotypic determination were estimated for each character analyzed as well as the ratio between the experimental and genetic variation coefficients. Next, mean tests and the analysis of the phenotypic and genotypic correlation were carried out. Results showed that the genotypes analyzed differed in regard to hypocotyl and epicotyl length and plant height, at the V2 and V3 stages of development. In addition, the estimated magnitude of the genetic parameters and genotypic correlations showed genetic influence on the phenotypic expression of the hypocotyl and epicotyl length and plant height at the V2 and V3 stages of development.
