1. Estimates of genetic parameters of pigments and agronomic traits in green and purple lettuce
RESUMO O entendimento da genética e das interações gênicas envolvidas na expressão de determinadas características se torna um fator determinante para a melhor exploração seu uso. Este desconhecimento das bases genéticas envolvidas impacta diretamente no desenvolvimento de programas de melhoramento que aliem uma ou mais características desejáveis

2. Epistasia para a produção de grãos e caracteres da planta em milho / Epistasis for yield and plant traits in maize
It is known that epistasis may have important effects in the populations dynamics and in the evolutionary process of the species, and that it is involved in manifestation of important biological phenomena, such as overdominance, inbreeding depression and heterosis. However, epistasis is considered one of the more complex aspects of quantitative genetics sinc

3. Efeito do gene CP4 EPSPS na produtividade de óleo em populações de soja / Effect of CP4 EPSPS gene on the oil yield of soybean populations
During the past few years, with the increase of the biodiesel international price and rising demand, there has been a larger interest in increasing the oil content of soybean cultivars. It is known that the high oil production is a function of yield. However, there are many factors that prevent cultivars from expressing their full yield potential, for exampl

4. Epistasia em testecrosses de milho / Epistasis in maize testcrosses
Epistasis has been known since the beginning of the genetics studies. However its contribution to genetic variance components and to plant breeding is not well understood. Most of the genetic models designed to study the inheritance of the quantitative traits consider the absence of epistasis although most of these analyses dont provide test for such assumpt

6. Diallel among soybean rust tolerant parents / Dialelo entre genitores de soja tolerantes à ferrugem asiática
This work started a cycle of selection throughout crosses among soybean lines with tolerance against soybean rust. The objectives were to increment the plant tolerance, to estimate useful genetic parameters for soybean breeding programs and to predict the most promising crosses to extract high yielding lines. A complete diallel, without reciprocal, among 10

7. Herança da produção de grãos e dos componentes de produção em soja / Inheritance of grain production and yield components in soybean
The knowledge of inheritance of traits is very important for breeding purposes. However, the inheritance is highly influenced by the environment and the genotypic composition of the population and thus, the accumulative information of estimates is very important for a better knowledge of the inheritance of quantitative traits. Most of the studies of inherita

8. Uma abordagem bayesiana para mapeamento de QTLs em populações experimentais / A Bayesian approach for mapping QTL in experimental populations
Many traits in plants and animals have quantitative nature, influenced by multiple genes. With the new molecular techniques, it has been possible to map the loci, which control the quantitative traits, called QTL (Quantitative Trait Loci). Mapping a QTL means to identify its position in the genome, as well as to estimate its genetics effects. The great diffi

9. Avaliação de genótipos de mamona (Ricinus communis L.) em cruzamentos dialélicos parciais / Evaluation of castor (Ricinus communis L.) genotypes in partial diallel crosses
Castor has been a very important crop in northeastern Brazil, and has been characterized as low input agriculture of small farmers. Nowadays it became a very important crop in other places of Brazil, due to the possibility of biodiesel production. Most of castor crop in Brazil is based in landraces and only a few cultivars were released by breeding programs.

10. Análise cariotípica em espécies dos gêneros Solanum, Lycianthes e Vassobia
The Solanum genus comprises about 1.400 species of shrubs, trees and wines, found preferentially in the tropical regions. Some of these with economic interests, as the potato. In relation to the cytogenetical features, this group is interesting by the fact of the karyotypes be sufficiently conserved in chromosome number and shape, with diversity in the repet

11. Características agronômicas e genéticas de Helicônias na Zona da Mata de Pernambuco. / Agronomic and genetics traits from Heliconia genotypes in the Pernambuco Forest Zone.
The genotypes of the Heliconia Germoplasm Collection of University Federal Rural of Pernambuco (UFRPE), implanted in December of 2003 in Camaragibe, were valued agronomic traits. In the first stage, information on number of shoots per clump (NPT) and the clump basal area (AOT) of 26 Heliconia spp. genotypes, cultivated at full sun and partial shade, accordin

12. Abordagem Bayesiana na análise genética de populações utilizando dados de marcadores moleculares. / Bayesian approach to the genetic analysis of populations using molecular markers data.
Among the various aspects generally considered in the genetic characterization of natural populations of plant species, the evaluation of the degree of genetic structure within and among individuals and the estimation of parameters related to the species mating system are of great importance. In general, considerable effort is focused on the estimation of th
