Amplified fragment length polymorphism markers were used to assess genetic diversity in 10 male sterile wheat crop lines (hetero-cytoplasm with the same nucleus) in relation to a restorer wheat line. These male sterile lines were evaluated using 64 amplified fragment length polymorphism primer combinations, and 13 primers produced polymorphic bands, generating a total 682 fragments. Of ... more
This study was designed to compare the genetic effects of elevated carbon dioxide (CO2) and ozone (O3), alone or in combination, under irrigated and non-irrigated conditions on proteins and DNA of wheat (Triticum aestivum L.). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), isozymes, random amplified polymorphic DNA (RAPD), and comet ... more
The aim of this study was to analyze the effects of high temperatures on ear fertility, yield components and protein content of wheat cultivars. Therefore, 96 genotypes were subjected to two environments in a greenhouse: control and heat stress. Each environment had two replicates, totalling 192 plots. The evaluations were: number of ear per plant, number of ear per pot, ear weight, number of ... more
We evaluated correlations between yield, meteorological and bromatological characters in five genotypes of dual-purpose wheat submitted to different cutting management systems. The experiments were carried out in 2014 and 2015. The experimental design was a randomized block, organized in a factorial scheme, with five genotypes of dual purpose wheat (BRS Tarumã, BRS ... more
Dual purpose wheat could be a good alternative for helping overcome the need to import this cereal in Brazil. To achieve this, development of cultivars with high yield is necessary. The contribution of genetics in defining traits is very important for directing breeding programs for the development of cultivars that provide the desired agronomic ideotype. We ... more
The management of nitrogen in wheat based on biological and environmental indicators can ensure productivity with a reduction in environmental impact. The objective of the study was to develop a more sustainable management of nitrogen use in wheat, considering the dose as a fraction of the total supply based on an estimate of the maximum technical and economic ... more
Nitrogen management distinctly influences the expression and magnitude of relationships between wheat ear components and grain yield. We sought to determine the variables linked to wheat ear that are more responsive to changes in the dose and form of nitrogen supply and to determine the direct and indirect effects on grain yield by single and fractional nitrogen ... more
Wheat is considered a basic cereal for civilization with great economic importance for world agriculture. Currently, wheat is planted in the south, southeast and midwest regions of Brazil. Brazilian consumption of wheat will grow in the coming years due to population increase, which will require developing new cultivars for non-tradtional regions. We investigated ... more
