Genetic parameters and selection of soybean lines based on selection indexes

Defining selection criteria is important to obtain promising genotypes in a breeding program. The objective of this study was to estimate genetic parameters for agronomic traits and to perform soybean line selection using selection indices. The experiment was conducted at an experimental area located at Capim Branco farm, belonging to the Federal University of Uberl.. Read More»

The soybean crop has a substantial importance for Brazil’s agribusiness and economy. Besides, breeding programs have contributed to the development of the crop in the country allowing grain yield increase and, at the same time, intensifying the production of new cultivars that show both yield predictability and wide adaptation. This study was aimed at evaluati.. Read More»

Phenotypic and genotypic correlations between soybean agronomic traits and path analysis

The goals of this research were to evaluate the phenotypic and genotypic correlations between agronomic traits, to perform path analysis, having as main character grain yield, and to identify indirect selection criteria for grain yield. The experiment was carried out in an experimental area located at Capim Branco farm, which belongs to Federal University of Uberl&a.. Read More»

Genotype x environment interaction and stability of soybean cultivars for vegetative-stage characters

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. This study was aimed at evaluating the .. Read More»
