1. Water uptake of soybean pods and seeds with different lignin contents
ABSTRACT The identification of pod- and seed-related traits of soybean genotypes and their interaction with water uptake can be applied in breeding programs with a view to establishing cultivars developed for the production and maintenance of high-quality seeds. The objective was to evaluate the water uptake of pods and seeds of soybean cultivars with differ

2. Superiority index based on target traits reveals the evolution of Brazilian soybean cultivars over last half-century
ABSTRACT The objective of this work was to assess the breeding influences in different agronomic and physiological traits in Brazilian soybean cultivars, released between 1965 and 2011, to identify traits associated with modern cultivars. A total of 29 cultivars were evaluated in two locations in the 2016/17 crop season. Genotype selection based on agronomic

3. Adaptability and stability of soybean cultivars in the region of Chapadões
ABSTRACT Grain yield is a constant concern in soybean breeding programs for being highly influenced by the environment. This trait can be significantly affected by the sowing times. Thus, for the correct cultivar recommendation, methods of stability and adaptability analysis are used to verify the genotype x environment interaction at different sowing times.

4. Uni and multivariate approaches for diallel analysis in early generation trials for soybean tolerance to rust
ABSTRACT Due to the high impact of Asian soybean rust (SBR) in Brazilian croplands, several studies have been conducted in order to maintain or increase the grain yield gain over years in the presence of the pathogen. The aim of this study was to define a breeding strategy applying uni and multivariate approaches for diallel analyzes in early generation tria

5. Identification of core locations for soybean breeding in Southern Brazil
Resumo: O objetivo deste trabalho foi identificar locais-chave de teste em duas macrorregiões sojícolas no Brasil, para avaliação e seleção de linhagens de soja (Glycine max). Foram testadas 22 cultivares em 23 locais, nessas duas macrorregiões (MR1 e MR2), durante quatro anos, de 2012 a 2015. Os ensaios foram conduzidos em delineamento de blocos ao a

6. Physiological and N2-fixation-related traits for tolerance to drought in soybean progenies
Resumo: O objetivo deste trabalho foi avaliar seis genótipos de soja (Glycine max) quanto aos parâmetros fisiológicos e à fixação biológica de nitrogênio, em condições de restrição hídrica, e sua capacidade de recuperação após reidratação, com base em componentes de produção. Os genótipos avaliados em casa de vegetação foram os seguint

7. Caracterização de genótipos de soja com resistência parcial à ferrugem da soja
RESUMO A ferrugem asiática da soja (FAS), causada pelo fungo Phakopsora pachyrhizi, é uma das doenças mais severas na cultura. Dentre as estratégias para seu manejo propõe-se a utilização de genótipos com resistência horizontal ou parcial, ainda restritos no mercado, mas promissores pela durabilidade da resistência. O objetivo deste trabalho foi av

8. Evaluation of soybean breeding lineages to new sources of root-knot nematode resistance
RESUMO No Brasil, as perdas causadas pelos nematoides aumentaram nas áreas produtoras à medida que a cultura da soja se expande. Portanto, este trabalho teve como objetivo desenvolver uma nova cultivar de soja não geneticamente modificada que combinasse características como resistência a nematoides, maturação precoce, alta produtividade de grãos e al

9. Isoflavone, anthocyanin, and fatty acid contents of vegetable-type soybean grains at different maturity stages
Resumo: O objetivo deste trabalho foi determinar os teores de óleo, proteína, ácidos graxos, isoflavonas e antocianinas, em grãos de soja de diferentes linhagens e estádios de maturação. Foram feitas avaliações quantos aos perfis químicos das linhagens com tegumento preto (BRM09-50995) e amarelo (BRM11-51428 e BRM08-50643), colhidas nos estágios d

10. Agronomic performance and genetic dissimilarity of second-harvest soybean cultivars using REML/BLUP and Gower’s algorithm
ABSTRACT The cultivation of second-harvest with soybean crop after first-harvest with maize crop has become an alternative to aggregate income to farmers in the South region of Brazil. However, there is little information about this cropping system in this region. The aims of this study were to: (i) evaluate the agronomic performance of soybean (Glycine max

11. SNP markers associated with soybean partial resistance to Phytophthora sojae
Abstract Phytophthora root and stem rot is one of the most aggressive diseases in soybean crop. The use of resistant cultivars is the main strategy to reduce losses caused by the pathogen. This study aims to identify SNP markers associated with genes or QTLs that provide soybean with partial resistance to Phytophthora sojae. A total of 169 soybean cultivars

12. Statistical methods to study adaptability and stability in breeding lines of food-type soybeans
ABSTRACT The grains of food-type soybean cultivars, which are characterized by the absence of lipoxygenases and the presence of high levels of proteins and isoflavones, are regarded as functional foods with high acceptance by consumers. However, few cultivars of food-type soybeans are currently available in the Brazilian market. The aim of this work was to s
