| Abstract | TOMÉ, Lívia Gracielle Oliveira, D.Sc., Universidade Federal de Viçosa, july, 2009. Biometric analysis and mapping of QTLs for drought tolerance in maize. Advisor: Cosme Damião Cruz. Coadvisors: Cláudia Teixeira Guimarães and Pedro Crescêncio Souza Carneiro. 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, climate change on the agricultural scenario in the face of these changes and the contribution of genetic improvement in mitigating the problems arising from global warming. Drought is a major environmental stresses that limit plant growth and consequently crop yields. Plants respond to water deficit and adapt to drought conditions through a variety of physiological and biochemical changes, including phenological changes. However, the losses in grain production in maize are severe when the crop is under water stress condition, which is one of the main limiting factors. Maize is particularly sensitive to water stress during the reproductive phase. National and international maize breeding programs, have considered the simultaneous study of (i) biometric analysis of traits related to drought and their correlation with grain yield and (ii) the use of |
