Estimates of genetic trend for carcass traits in a commercial broiler line
Authors: J.L.B.M. Grosso J.C.C. Balieiro J.P. Eler J.B.S. Ferraz E.C. Mattos T. Michelan Filho A.M. Fel�?cio F.M. Rezende
Data from the slaughter of 24,001 chickens that were part of a selection program for the production of commercial broilers were used to estimate genetic trend for absolute carcass (CW), breast meat (BRW), and leg (LW) weights, and relative carcass (CY), breast meat (BRY), and leg (LY) weights. The components of (co)variance an.. Read More»

Changes in inflorescence protein during advanced stages of floret development in Buchloe dactyloides (Poaceae)
Authors: Y.-J. Zhou J.-G. Xue X.-G. Wang X.-Q. Zhang
Buffalograss, Buchloe dactyloides, is a dioecious species native to the Great Plains of North America. The florets at the early stages of development possess both gynoecium and androecium organ primordia but later become unisexual. Very little is known about the proteomic changes that occur when the florets change from hermaph.. Read More»

Genetic dissection of upland cotton (Gossypium hirsutum) cultivars developed in Hubei Province by mapped SSRs
Authors: J.L. Tu, M.J. Zhang, X.Q. Wang, X.L. Zhang and Z.X. Lin
The genetic diversity of 51 upland cotton cultivars with different parental origins and breeding periods that were developed in Hubei Province was studied on the basis of 237 mapped simple sequence repeat markers covering the cotton genome. A total of 108 polymorphic primer pairs amplified 196 loci; the polymorphism information content range was 0.04 to 0.83.. Read More»

Bayesian approach increases accuracy when selecting cowpea genotypes with high adaptability and phenotypic stability
Authors: L.M.A. Barroso1*, P.E. Teodoro2*, M. Nascimento1, F.E. Torres2, A. dos Santos3, A.M. Corr�?ªa2, E. Sagrilo4, C.C.G. Corr�?ªa2, F.A. Silva2 and G. Ceccon5
This study aimed to verify that a Bayesian approach could be used for the selection of upright cowpea genotypes with high adaptability and phenotypic stability, and the study also evaluated the efficiency of using informative and minimally informative a priori distributions. Six trials were conducted in randomized blocks, and the grain yield of 17 upright.. Read More»

Identification of QTLs of resistance to white mold in common bean from multiple markers by using Bayesian analysis
Authors: L.A.C. Lara, J.B. Santos, M. Balestre, I.A. Lima, A.K.A. Pamplona,J.S. Veloso and P.H. Silva
In this study, we identified simple sequence repeat, amplified fragment length polymorphism, and sequence-related amplified polymorphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and usi..

Development of cassava periclinal chimera may boost production
Authors: N. Bomfim and N.M.A. Nassar
Plant periclinal chimeras are genotypicmosaics arranged concentrically. Trials to produce them to combine different species have been done, but pratical results have not been achieved. We report for the second time the development of a very productive interspecific periclinal chimera in cassava. It has very large edible roots .. Read More»

Early diagnosis of a Mexican variant of Papaya meleira virus (PMeV-Mx) by RT-PCR
Authors: E. Zamudio-Moreno, J.H. Ramirez-Prado, O.A. Moreno-Valenzuela and L.A. Lopez-Ochoa
Papaya meleira disease was identified in Brazil in the 1980s. The disease is caused by a double-stranded RNA virus known as Papaya meleira virus (PMeV), which has also been recently reported in Mexico. However, previously reported PMeV primers failed to diagnose the Mexican form of the disease. A genomic approach was used to identify sequences of the Mexi.. Read More»

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

Lactic acid bacteria dynamics during spontaneous fermentation of cocoa beans verified by culture-independent denaturing gradient gel electrophoresis
Authors: T.F. Santos, L.K.A. Santana, A.C.F. Santos, G.S. Silva, C.C. Romano, J.C.T. Dias and R.P. Rezende
Cocoa is naturally fermented in the field before the cocoa seeds are removed for processing. We assessed the dynamics of lactic acid bacteria during cocoa fermentation in Bahia, Brazil. During five days of fermentation, temperature and pH were measured and beans were collected for genomic DNA extraction every 12 h. The DNA was.. Read More»

Genetic diversity in a germplasm bank of Oenocarpus mapora (Arecaceae)
Authors: E.F. Moura M.S.P. de Oliveira
Oenocarpus mapora is an Amazonian palm species commonly used by native populations for food and in folk medicine. We measured genetic variability, using RAPD markers, of material kept in a germplasm bank composed of accessions sampled from the Brazilian Amazon. These included 74 individuals from 23 accessions sampled from 9 localities in three States of t.. Read More»
