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...
Inbreeding depression and genetic variability in agricultural traits and resist...
Oliveira, Aurilene Santos; Reis, Edésio Fialho dos; Nogueira, Ana Paula Oliveira; Cezar Juliatti, FernandoThe effect known as depression by inbreeding refers to the reduction on the average value of quantitative traits, related to plant reproduction and physiology, due to the homozygosis of deleterious alleles. This study evaluated the inbreeding depression and the genetic variability of agricultural traits and of the resistance to phytopathogens in inbred families of two exotic maize populations. The e...

Adaptability and stability of soybean cultivars in four sowing seasons
Bicalho, Thaís Ferreira; Nogueira, Ana Paula Oliveira; Hamawaki, Oswaldo Toshiyuki; Costa, Solange Celestino; Morais Júnior, Ivair José deIn recent decades, the expansion of soybean production in Brazil has been observed. This advance was motivated by the search of environments with better cultivation conditions, as well as the development of genotypes with wide adaptation. The diversity of "environments" hinders the process of selection and recommendation of cultivars, since the productive potential of a cultivar is given as a function of the su...
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...
Genetic diversity in soybean genotypes with resistance to Heterodera glycines
Matsuo, Éder; Sediyama, Tuneo; Cruz, Cosme Damião; Oliveira, Rosângela D'Arc de Lima; Oliveira, Rita de Cássia Teixeira; Nogueira, Ana Paula OliveiraEste trabalho teve como objetivo analisar a diversidade genética entre genótipos de soja inoculados com Heterodera glycines, raça 3. Os experimentos foram conduzidos sob condições de casa de vegetação. Foram avaliados 27 genótipos de soja sob dois ensaios de análise do comportamento quanto às características morfoagronomicas e de resistência ao patógeno. Estimou- se o coeficiente de determinação genotípica, a p...
Reaction of brazilian cotton genotypes to white mold depends on pathogen aggres...
Pestana, Jeferson Rodrigo; Morais, Tâmara Prado de; Nogueira, Ana Paula Oliveira; Cezar Juliatti, FernandoThe expansion of cotton crop into irrigated and high lands of Brazilian Cerrado, despite the possibility of increasing fiber yield, led to the occurrence of diseases previously considered secondary, such as white mold [Sclerotinia sclerotiorum (Lib.) de Bary]. Host genetic resistance is of extreme importance in integrated strategies to manage this disease. Resistance of Brazilian cotton genotypes, challenged wi...
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...
