1. Genetic variability and breeding potential of Flintisa Composite of maize in two levels of technology
Abstract The purpose this study was to verify the breeding potential of Flintisa Composite for low (LT) and high (HT) technology of cultivation, and the best selection strategy to be adopted. For this reason half-sib progenies were evaluated in the two technological levels. In HT, it was used basic fertilization, two top dressing and supplementary irrigation

2. Study of repeatability and phenotypical stabilization in kale using frequentist, Bayesian and bootstrap resampling approaches
ABSTRACT. The aim of this study was to obtain information for the genetic improvement of kale through repeatability and phenotypic stabilization studies and to compare methodologies that represent the reliability of the estimated parameters. Thirty-three half-sib progenies were evaluated in a randomized block design with three replicates and six plants per p

3. Recurrent selection of popcorn composites UEM-CO1 AND UEM-CO2 based on selection indices
ABSTRACT Selection indices were applied to data sets of 169 half-sib families of the popcorn composites UEM-Co1 and UEM-Co2 in four cycles of recurrent selection. From 2005 to 2008, the experiments were arranged in a 13 by 13 lattice square design, with two replications per cycle and composite. Genetic gains for popping expansion (PE) and grain yield (GY) we

4. Successful Identification of Duck Genome Region Determining Desirable Uniformity of Meat Performance Traits
ABSTRACT The objective of this study was to identify genome regions determining duck meat performance traits with possible small variation. In total, 368 crossbred ducks of F2 generation obtained from two parental lines: Pekin-type ducks of Polish origin (A55) and Pekin-type ducks of French origin (GL-30) were recorded. The following seven traits were analyz

5. Effect of recurrent selection on the variability of the UENF-14 popcorn population
Abstract This study aimed to evaluate the effect of recurrent selection on the genetic variability of UENF-14 population after six selections. Two hundred and ten half-sib families were evaluated in two environments in the state of Rio de Janeiro, using incomplete randomized blocks design with treatments arranged in replication within "Sets". There was signi

6. Genetic variability for carotenoid content of grains in a composite maize population
Local maize (Zea mays L.) varieties are cultivated by small-scale farmers in western Santa Catarina (SC) State, in southern Brazil. These small areas frequently present many problems related to biotic and non-biotic stresses, which have limited the economic output and income of the farmers. Production from local varieties for human consumption would be an al

7. Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced

8. Genetic diversity based on morphological data in Panicum maximum hybrids
The objective of this experiment was to evaluate the genetic divergence between hybrids obtained from 10 sexual genitors of the Panicum maximum breeding program at Embrapa Beef Cattle. For this, the following morphological descriptors were used: plant height, growth habit, leaf aspect, leaf waxiness, hair density on the sheath (DePB) and blade (DePL), degree

9. Heterogeneity of linalool chemotypes of Lippia alba (Mill.) N.E.Br., based on clonal half-sib progenies
Lippia alba (Mill.) N.E.Br. is an aromatic and medicinal shrub native to the American continent. Despite its potential as a source of essential oil for the pharmaceutical and cosmetics industries, few selection and genetic improvement studies have been carried out. The aim of this study was to provide genetic information on this species for breeding programs

10. Selection via simulated individual BLUP based on family genotypic effects in sugarcane.
The objective of this work was to propose a new selection strategy for the initial stages of sugarcane improvement, based on the methodology 'simulated individual BLUP (BLUPIS)', which promotes a dynamic allocation of individuals selected in each full-sib family, using BLUP as a base for both the genotypic effects of the referred families and plot effects.

11. Estimativas de parâmetros genéticos na população de milho CMS 35 no Estado de Sergipe.
O objetivo deste trabalho foi estimar parâmetros genéticos da população CMS 35 submetida a três ciclos de seleção entre e dentro de progênies de meios-irmãos, em diferentes municípios do Estado de Sergipe, no período de 1998 a 2000. Foram avaliadas 196 progênies de meios-irmãos em cada ciclo de seleção, em látice simples 14x14, em dois locais

12. Seleção em progênies de maracujazeiro-amarelo com base em índices multivariados.
O objetivo deste trabalho foi avaliar os ganhos genéticos, preditos por meio de diferentes índices de seleção, em seis caracteres relacionados ao fruto, em 16 progênies de meios-irmãos de maracujá-amarelo. Foram utilizados: o índice clássico de Smith & Hazel (IC) e a distância genótipo-ideótipo de Cruz (IDGI), ambos com três pesos econômicos; o
