Harvesting delay in physiological quality of soy seeds
Ferreira, Sílvia Barbosa; Hamawaki, Osvaldo Toshiyuki; Nogueira, Ana Paula Oliveira; Thesing, Larissa; Machado, Beliza Queiroz VieiraSoybeans are a grain-producing species of high international demand and occupy a prominent position in the Brazilian economy. The success of this crop in Brazil is due to public and private investments in production technologies and to breeding programs. It is through the seed that the genetic advances reach the producer. In this context, the success of a cultivar and high productivity depend on the quality of ...
Effect of sowing season on soybean performance
Mattos, Thúlio Pereira; Hamawaki, Osvaldo Toshiyuki; Nogueira, Ana Paula Oliveira; Luiz, Marlize Cristina Pinheiro; Teixeira, Fernanda GabrielaThe soybean presents great economic expression and high impact in the Brazilian agribusiness. The productive potential of a cultivar is expressed according to the genetic constitution and the environment. The sowing time exerts influence on the agronomic traits of the soybean, impacting the yield of grains. The objective of this study was to evaluate the influence of the sowing season on the productive potentia...

No. of bitstreams: 0 Previous issue date: 2020-01-01; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Soy is one of the main cultivated species in the world with great economic expression and high impact on Brazilian agribusiness. The productive potential is expressed due to the genetic constitution of the cultivar and the environment ...
Selection of lineages, genetic parameters, and correlations between soybean cha...
Vianna, Mariana Silva; Nogueira, Ana Paula Oliveira; Hamawaki, Osvaldo Toshiyuki; Sousa, Larissa Barbosa de; Gomes, Géssyca FerreiraSoybean has great economic importance in the world accordingly, this legume has been exploited in breeding programs aiming to provide cultivars with extensive grain yield, tolerant to pests and diseases, and adapted to different soil and climatic conditions. Therefore, the objectives of this work were to evaluate genetic parameters and correlations between soybean traits to select lineages to increase yield and...
Adaptability and productive stability of soybean genotypes under natural rust i...
Silva, Nathália Salgado; Nogueira, Ana Paula Oliveira; Hamawaki, Osvaldo Toshiyuki; Marques, Fábio Serafim; Medeiros, Luíza AmaralThe genetic breeding of soybean aims to obtain productive genotypes, so it is necessary that the genetic components, environment and the interaction between them be understood. The G x E interaction is the differential behavior of the genotypes against environmental. The objective was to study the G x E interaction and analyze the adaptability and stability of soybean genotypes under natural rust infection with...
New high-yielding conventional soybean adapted to the states of Goiás, Minas Ge...
Hamawaki, Raphael Lemes; Hamawaki, Osvaldo Toshiyuki; Nogueira, Ana Paula Oliveira; Juliatti, Fernando Cezar; Glasenapp, Jacqueline SiqueiraThis paper aims to present the features of the new soybean cultivar UFUS Milionária, which was developed by the Soybean Improvement Program of the Federal University of Uberlândia (UFU) through crossing between IAC-100 and Cristalina RCH cultivars, using the Single Seed Descent (SSD) method. UFUS Milionária is resistant to many diseases caused by the fungus, bacteria, and virus. In addition, it also has been pr...
Agronomic performance and genetic diversity among lines and soybean cultivars
Machado, Beliza Queiroz Vieira; Nogueira, Ana Paula Oliveira; Hamawaki, Osvaldo Toshiyuki; Jorge, Gabriel Lemes; Rezende, Gabriel FernandesKnowledge of genetic diversity is of great importance to the contribution of plant breeding, as it helps plant breeders to better selecting parents for establishment of segregating populations. This knowledge is especially important to crops that presents a narrow genetic base as soybean. The objective of this work was to assess agronomic performance and genetic diversity of lines and soybean cultivars, in orde...
Dissimilarity measures and hierarchical methods for the study of genetic divers...
Rodrigues, Bárbara; Gomes, Ana Paula Rodrigues; Gomes, Josiane Dias; Serafim, Fábio; Nogueira, Ana Paula Oliveira; Hamawaki, Cristiane Divina LemesIn analysis of the genetic diversity on soybean can be used agronomic, morphological and molecular traits, which are subjected to multivariate biometrical analysis. There are different multivariate methodologies available such as Euclidean distance, Mahalanobis distance and different hierarchical methods. However, studies that may assist in the choice of such methods are lacking. The aim of this paper was to ev...
Parametric and non-parametric analysis for determining the adaptability and sta...
Romanato, Fernanda Neves; Hamawaki, Osvaldo Toshiyuki; Sousa, Larissa Barbosa de; Nogueira, Ana Paula Oliveira; Carvalho Neto, Dão Pedro deThe use of different evaluation methods of adaptability and stability in a breeding program is essential to obtain more accurate results of the lines that have been studied. The purpose of this research is to study the adaptability and stability of 25 soybean lines derived from the soybean breeding program, and for that, it was used parametric and non-parametric analysis at the Federal University of Uberlandia....
Correlation between yield components in F6 soybean progenies derived from seven...
de Sousa, Larissa Barbosa; Santos Júnior, Célio Dias; Romanato, Fernanda Neves; Hamawaki, Osvaldo Toshiyuki; Nogueira, Ana Paula OliveiraBreeding programs strive to obtain cultivars with superior traits. The association between these characters, such as those estimated by correlation coeficients, are important to the breeding selection process. In this study we analyzed phenotypic and genotypic correlations between yield and other agronomic traits in soybean progenies derived from various crosses to support breeding line selection in the the soy...
