Selection of maize inbred lines and gene expression for resistance to ear rot

In recent years, there has been a large incidence of fungi causing “ear rot” in maize in Brazil, the main fungus being Fusarium verticillioides. The most efficient and competitive alternative for control of this disease consists of using maize hybrids resistant to this pathogen. Thus, the aims of this study were to analyze the genetic variability of maiz.. Read More»

A comparative framework of the Erythrina velutina tree species in reforested land and native populations

    E.M.S. Souza, G.S. Pereira, R. Silva-Mann, S.V. Álvares-Carvalho and R.A. Ferreira

Erythrina velutina Willd. (Fabaceae: Papillionoideae) is a pioneer species found in tropical and subtropical regions of the world that has medicinal properties and that is used in reforestation projects. This species is rare in some areas of northeastern Brazil. This study aimed to characterize and compare genetic structures of natural and restored populations of E... Read More»

Indirect selection for resistance to ear rot and leaf diseases in maize lines using biplots

    G.S. Pereira, R.B. Camargos, M. Balestre, R.G. Von Pinho and W.M. C. Melo

Leaf disease and ear rot have caused reductions in maize yield in Brazil and other producer countries. Therefore, the aims of this study were to analyze the association between husked ear yield and the severity of maize white spot, gray leaf spot, helminthosporium, and ear rot caused by Fusarium verticillioides and Diplodia maydis using biplots in a mixed-model approach. The responses of 238 li.. Read More»

Identification of earl millet cultivars using both microsatellites and enzymatic markers

    R.P. Mendonça Neto E.V.R. Von Pinho B.L. Carvalho G.S. Pereira

The increasing number of protected and registered cultivars and problems involving seed commercialization make distinction and identification of cultivars imperative. Millet (Pennisetum glaucum), a crop species with protected cultivars in Brazil, has been the target of seed piracy. Thus, with the objective of identifying different lots with regard to origin, we characterized six cultivars of comme.. Read More»
