1. 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

2. 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

3. Stomatal conductance of maize under water and nitrogen deficits
The objective of this work was to evaluate the effect of drought and nitrogen (N) stresses on stomatal conductance of three maize cultivars grown in the field. The stomatal conductance of Sol da Manhã variety (BRS 4157) and Pioneer 6875 hybrid, under drought and high N, was lower than under drought and low N, which indicates drought tolerance, since these c

4. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima
