Phenotypic and predicted genetic approaches for genotype ranking of wheat seed yield in Brazil

This work was aimed at determining stability and adaptability through Additive Main Effects and Multiplicative Interaction (AMMI) and Genotype Main Effects and Genotype Environment Interaction (GGE) methodologies, as well as to estimate and predict Restricted Maximum Likelihood/Best Linear Unbiased Prediction (REML/BLUP) parameters and employ them in multivariate mo..

Genetic progress in oat associated with fungicide use in Rio Grande do Sul, Brazil

    D.N. Follmann, A. Cargnelutti Filho, A.D. Lúcio, V.Q. de Souza, M. Caraffa and C.A. Wartha

The State of Rio Grande do Sul (RS) is the largest producer of oat in Brazil with the aid of consolidated breeding programs, which are constantly releasing new cultivars. The main objectives of this study were to: 1) evaluate the annual genetic progress in grain yield and hectoliter weight of the oat cultivars in RS, with and without fungicide use on aerial parts of..

REML/BLUP and sequential path analysis in estimating genotypic values and interrelationships among simple maize grain yield-related traits

    T. Olivoto, M. Nardino, I.R. Carvalho3, D.N. Follmann4, M. Ferrari3, V.J. Szareski5, A.J. de Pelegrin3 and V.Q. de Souza6

Methodologies using restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) in combination with sequential path analysis in maize are still limited in the literature. Therefore, the aims of this study were: i) to use REML/BLUP-based procedures in order to estimate variance components, genetic parameters, and genotypic values of simple maize hybrids.. Read More»

Genetic progress in homogeneous regions of wheat cultivation in Rio Grande do Sul State, Brazil

    D.N. Follmann, A. Cargnelutti Filho, A.D. Lúcio, V.Q. de Souza, M. Caraffa, C.A. Wartha

The State of Rio Grande do Sul (RS) stands out as the largest wheat producer in Brazil. Wheat is the most emphasized winter cereal in RS, attracting public and private investments directed to wheat genetic breeding. The study of genetic progress should be performed routinely at breeding programs to study the behavior of cultivars developed for homogeneous regions of.. Read More»

Estimates of genetic parameters and genotypic values prediction in maize landrace populations by REML/BLUP procedure

Lung cancer is the leading cause of cancer death in men and the second leading cause of cancer death in women worldwide. Fascin-1 and laminin-5 were associated with the invasiveness and prognoses of several cancers. The expression and the serum levels of fascin-1 and laminin-5 in patients with non-small cell lung cancer (NSCLC) were analyzed in this study. The expre.. Read More»

Diallel and prediction (REML/BLUP) for yield components in intervarietal maize hybrids

Genetic improvement is essential to achieve increments in maize (Zea mays L.) grain yield components. It may be obtained through crosses, which enable to exploit the effects of intervarietal heterosis, allelic complementarity, as well as gene actions and effects. This study estimated the components of variance and genetic parameters (REML/BLUP) of an intervarietal d.. Read More»

Univariate, multivariate techniques and mixed models applied to the adaptability and stability of wheat in the Rio Grande do Sul State

The wheat crop presents sensitivity to the environmental conditions culminating in the genotype x environment interaction, being crucial the use of different methodologies to guide the positioning of genotypes to certain cultivation environments. The objective of this study was to estimate the adaptability and phenotypic stability of wheat genotypes grown in the Sta.. Read More»
