Introduction
I am an agronomist and a young plant breeder with experience and interests in genetics, plant breeding, field experimentation, statistics, quantitative genetics, biometry, phenomics and genomics. My current research focus on the application of quantitative genetic approaches for the analysis of phenotypic and genotypic information derived from high-throughput phenotyping and genotyping platforms in breeding programs of economically important crops, such as maize and wheat.

Article
Full-text available
Estimating the combining ability in wheat (Triticum aestivum L.) parents is a crucial tool for selecting promising segregating populations with potential to generate genotypes adapted to the Brazilian tropical regions, supporting the wheat production expansion. This study aimed to estimate the general and specific combining abilities of wheat paren...
Article
Full-text available
The study of genotypic relationships between drought tolerance indices and agronomic traits of interest in wheat breeding is useful for designing selection strategies. The objective of this research was to investigate the cause-and-effect relationships between agronomic traits and drought tolerance indices through the analysis of canonical correlat...
Article
Full-text available
In many cases, traditional analysis of breeding trials based on analysis of variance (ANOVA) do not allow a suitable genetic evaluation. Alternatively, mixed model-based approaches create the possibility of dealing with unbalanced data and modeling spatial trends. The aims of this study were to compare the goodness-of-fit of the model and the genot...
Article
Full-text available
High-throughput phenotyping (HTP) approaches are potentially useful for designing indirect selection strategies, which consists in the selection of a primary target trait X based on secondary trait Y. Usually, the secondary trait Y is correlated to the target trait X and is easier, faster and cheaper to measure. In this context, the use of secondar...
Article
Full-text available
The selection of parents to originate promising base populations, as well as the knowledge of the gene effects controlling agronomic traits by means of diallel, are useful to drive genetic gains in Brazilian tropical wheat breeding programs. The goals of this study were to select tropical wheat parents with a high frequency of favorable alleles and...
Article
Full-text available
Recurrent selection is an effective breeding method for improving complex traits in wheat (Triticum aestivum L.) breeding. In this study, we propose a genitor selection strategy, employing a multi‐trait selection approach and genetic diversity analysis. To evaluate our proposed method, we conducted a lattice design trial during the winter seasons o...
Preprint
Full-text available
The selection of segregating populations is a key point in plant breeding programs. These should gather favorable phenotypes for multiple target characters, which makes it difficult to identify populations with high potential. Thus, this research aims to select potential wheat populations with precocity and grain yield by multivariate and multigene...
Preprint
High-throughput phenotyping (HTP) approaches are potentially useful for the accurate and efficient evaluation and selection of superior genotypes, leveraging high genetic gains. Vegetation indices are of particular interest because they allow indirect selection. Considering the lack of information regarding high-throughput phenotyping approaches in...
Article
Full-text available
The immediate need for the increase in wheat production to meet the future world demand, associated with the occurrence of drastic climatic events, such as drought, makes it necessary to develop drought-resilient genotypes. The aims of this work were to evaluate the use of drought-tolerance indices for the selection of wheat genotypes, to compare t...
Article
Full-text available
The early stages of wheat breeding programs often contain large number of plants in segregating populations that must be selected. Selecting the best populations and plants in those stages is not an easy task, making it necessary to use robust methodologies that facilitate the selection process. The goals of this work were to evaluate different met...
Article
Full-text available
The selection of segregating populations with the potential for derived lines is essential for breeding programs. The present work analyzes the potential of tropical F2 wheat (Triticum aestivum L.) populations originated from complete diallel cross combinations. For this purpose, eight tropical wheat cultivars were combined in a complete diallel de...
Article
Full-text available
Although Brazil is one of the main agricultural countries in the world, it is historically an importer of wheat. For this reason, strategies aimed at the expansion of wheat in the country, to areas that are not traditionally producing (warmer), are of paramount importance. In wheat breeding, phenotypic values are usually used in simultaneous select...
Article
Full-text available
Canonical correlation analysis based on genotypic correlations allows determining the associations between groups of traits and carrying out the direct or indirect selection of superior genotypes. This study investigated the existence of linear and multivariate relationships between high and low heritability traits via canonical correlation analysi...
Article
Full-text available
Genetic diversity studies and analysis of the selection gain of wheat (Triticum aestivum L.) genotypes released over the decades allow the planning of strategies and support decision‐making for crossing in wheat breeding. We investigated genetic diversity in tropical wheat germplasm, discussed the main trends in breeding programs and selected poten...
Article
Full-text available
The differential response of lines to the variation of environments makes it necessary to use robust biometric tools for efficient evaluation and selection of wheat lines in tropical regions of Brazil. The objective of this work was to select tropical wheat lines with high grain yield, adaptability, and stability for the Central region of Brazil us...
Article
Full-text available
The aims of this study are to verify the existence of canonical correlations between physiological and agronomic traits of 40 lines of tropical wheat using the REML/BLUP (restricted maximum likelihood/best linear unbiased prediction) method and select genotypes with the best performance using four selection indexes. For such, 40 tropical wheat geno...
Article
Selecting potential progenies in early inbred generations is an essential step towards the success of breeding programs. Given this, the use of top crosses assists breeders in selecting progenies to generate lines with the potential for hybrid yield. Thus, the purpose of this study was to assess the behavior of partially inbred progenies (S1) of ma...
Article
Full-text available
The purpose of this study was to select top cross hybrids of green maize for yield, derived from partially inbred S1 lines based on genetic values using the REML/Blup method, and to estimate important genetic parameters for green maize breeding programs. The experiment was conducted in an experimental area located between 17º53´ S and 52º43´ W, 680...
Article
Full-text available
The objective of this work was to define the most suitable selective strategy for the simultaneous increment of yield components of green maize, by comparing three selection indexes weighted by economic weights and by the REML/BLUP method, in the assessment of predicted genetic gains for traits of interest. An experiment with 75 topcross hybrids fr...
