Genetic damage in Mexican and South American sweet corn varieties due to the use of herbicides (Nicosulfuron and Topramezone)
Authors: M.S. Reynoso, C.M. Alvarez, L.L. De la Cruz, J.F.G. Landeros, J.J.G. S�¡nchez, A.R.A. Villalobos
In order to encourage corn production, several herbicides such as nicosulfuron and topramezone are used. Though they offer great advantages, they may affect crop productivity and may even induce DNA damage. This study evaluated genotoxic activity at two nicosulfuron concentrations (40,000 and 80, 000 ppm) and at four topramezone concentrations (1480, 148,.. Read More»

Indices estimated using REML/BLUP and introduction of a super-trait for the selection of progenies in popcorn
Authors: C. Vittorazzi, A.T. Amaral Junior, A.G. Guimar�£es, A.P. Viana, F.H.L. Silva, G.F. Pena, R.F. Daher, I.F.S Gerhardt, G.H.F. Oliveira and M.G. Pereira
Selection indices commonly utilize economic weights, which become arbitrary genetic gains. In popcorn, this is even more evident due to the negative correlation between the main characteristics of economic importance - grain yield and popping expansion. As an option in the use of classical biometrics as a selection index, the .. Read More»

Diallel and prediction (REML/BLUP) for yield components in intervarietal maize hybrids
Authors: I.R. Carvalho, A.J. de Pelegrin, V.J. Szareski, M. Ferrari, T.C. da Rosa, T.S. Martins, N.L. dos Santos, M. Nardino, V.Q. de Souza, A.C. de Oliveira and L.C. da Maia
Genetic improvement is essential to achieve increments in maize (Zea mays L.) grain yield components. It may be obtained through crosses, which enable to exploit the effects of intervarietal heterosis, allelic complementarity, as well as gene actions and effects. This study estimated the components of variance and genetic para.. Read More»

Efficiency of selection per se and in single-cross hybrids for disease resistance in maize
Authors: R.B. Camargos, R.G. Von Pinho, M. Balestre, R.A.D.C. Ferreira, K.O.G. Dias, L.P.M. Pires and V.F. Souza
Plant breeding strategies are constantly refined to increase efficiency during the selection process. Consequently, the aims of this study were to examine genetic control and efficiency of selection based on the per se performance of maize lines and based on hybrid performance in reaction to white spot, common rust, and ear ro..

Lung cancer is the leading cause of cancer death in men and the second leading cause of cancer death in women worldwide. Fascin-1 and laminin-5 were associated with the invasiveness and prognoses of several cancers. The expression and the serum levels of fascin-1 and laminin-5 in patients with non-small cell lung cancer (NSCLC.. Read More»

Expressed sequence tags related to nitrogen metabolism in maize inoculated with Azospirillum brasilense
Authors: L. Pereira-Defilippi, E.M. Pereira, F.M. Silva and G.V. Moro
The relative quantitative real-time expression of two expressed sequence tags (ESTs) codifying for key enzymes in nitrogen metabolism in maize, nitrate reductase (ZmNR), and glutamine synthetase (ZmGln1-3) was performed for genotypes inoculated with Azospirillum brasilense. Two commercial single-cross hybrids (AG7098 and 2B707.. Read More»

Genetic divergence among sweet corn lines estimated by microsatellite markers
Authors: A.D. Lopes1, C.A. Scapim2, C.A. Mangolin3 and M.F.P.S. Machado3
The purpose of this study was to analyze the genetic diversity of 15 sugary-1 sweet corn lines by microsatellite markers. One hundred pairs of simple sequence repeat primers that were mapped for field corn were tested. Of these primers, 15% were polymorphic, and all were selected for the evaluation. These primers identified a total of 39 alleles among the.. Read More»

Relationship between genetic parameters in maize (Zea mays) with seedling growth parameters under 40-100% soil moisture conditions
Authors: R.W. Muhammad and A. Qayyum
We estimated the association of genetic parameters with production characters in 64 maize (Zea mays) genotypes in a green house in soil with 40-100% moisture levels (percent of soil moisture capacity). To identify the major parameters that account for variation among the genotypes, we used single linkage cluster analysis and principle component analysis. .. Read More»

QTLs for days to silking in a recombinant inbred line maize population subjected to high and low nitrogen regimes
Authors: Z.P. Zheng, X.H. Liu, Y.B. Huang, X. Wu, C. He and Z. Li
Days to silking (DTS) is one of the most important traits in maize (Zea mays). To investigate its genetic basis, a recombinant inbred line population was subjected to high and low nitrogen (N) regimes to detect quantitative trait loci (QTLs) associated with DTS. Three QTLs were identified under the high N regime; these explain.. Read More»
