Agronomic trait; Asian rust; Glycine max; Indirect selection

Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this study, we ... more

Glycine max; Molecular markers; NIR; SSR

The present study was undertaken to detect and map the quantitative trait loci (QTL) related to soybean oil content. We used 244 progenies derived from a bi-parental cross of the Lineage 69 (from Universidade Estadual Paulista “Júlio de Mesquita Filho”/Faculdade de Ciências Agrárias e Veterinárias - Breeding Program) and Tucunaré cultivar. A total of 358 simple sequence repeat (SSR; ... more

genetic breeding; Genetic diversity; Glycine max

This study aimed to evaluate the clustering pattern consistency of soybean (Glycine max) lines, using seven different clustering methods. Our aim was to evaluate the best method for the identification of promising genotypes to obtain segregating populations. We used 51 generations F5 and F6 soybean lines originating from different hybridizations and backcrosses obtained from the ... more

clustering method; Genetic divergence; Glycine max

The objectives of this study were to use mixed models to confirm the presence of genetic variability in 16 soybean genotypes, to compare clusters generated by artificial neural networks (ANNs) with those created by the Ward modified location model (MLM) technique, and to indicate parental combinations that hold promise for obtaining superior segregating populations of soybean. A field ... more

Germplasm; Glycine max; Multivariate analysis; Plant introduction

Owing to the narrow genetic basis of soybean (Glycine max), the incorporation of new sources of germplasm is indispensable when searching for alleles that contribute to a greater diversity of varieties. The alternative is plant introduction, which may increase genetic variability within breeding programs. Multivariate techniques are important tools to ... more

Generation Analysis; Genetic parameters; Glycine max
 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
greenhouse ... more

Biological control; Glycine max; Soybean Stalk Fly; Soybean Stem Fly

Soybean stem fly (SSF), Melanagromyza sojae is an important pest in soybean growing regions of the Old World, and recently has been confirmed in soybean areas in Brazil, Paraguay and Bolivia. In the regions where it is endemic, the management of M. sojae is performed by using resistant varieties, chemical insecticides and natural control carried ... more

Breeding; Damaged seeds; Euschistus heros; Glycine max

The soybean crop is undoubtedly important to not only Brazil but also for most parts of the globe, as economic and social dependency upon this crop becomes evident. However, the scenario of the soybean crop production has faced challenges with environmental changes, which have escalated the incidence of pests. Due to the abundance of stink bugs, especially ... more
