High concentrations of sacharose lead to metabolic changes that favor the formation of co-products in ethanolic fermentation by Zymomonas mobilis

Z. mobilis has attracted great biotechnology interest in recent decades due to its unique metabolism and the ability to produce bioethanol from simple sugars in an effectively and quickly way. Z. mobilis also produce other bioactive products as fructose, gluconic acid, sorbitol, levan, fructo-oligosaccharides. This study aimed to identify proteins differentially expressed by Z. mobilis ZAG-12 u.. Read More»

Path analysis and canonical correlations for indirect selection of Jatropha genotypes with higher oil yield

    L.A. Silva, L.A. Peixoto, P.E. Teodoro, E.V. Rodrigues, B.G. Laviola, L.L. Bhering

Jatropha is a species with great potential for biodiesel production, and the knowledge on how the main agronomic traits are correlated will contribute to its improvement. Therefore, the objectives of this study were to estimate the genetic parameters of the traits: plant height at 12 and 40 months, canopy projection on the row at 12 and 40 months, canopy projection ..

Multivariate diallel analysis allows multiple gains in segregating populations for agronomic traits in Jatropha.

    P.E. Teodoro, E.V. Rodrigues, L.A. Peixoto, L.A. Silva, B.G. Laviola, L.L. Bhering

Jatropha is research target worldwide aimed at large-scale oil production for biodiesel and bio-kerosene. Its production potential is among 1200 and 1500 kg/ha of oil after the 4th year. This study aimed to estimate combining ability of Jatropha genotypes by multivariate diallel analysis to select parents and crosses that allow gains in important agronomic traits. W.. Read More»

Diallelic analysis to obtain cowpea (Vigna unguiculata L. Walp.) populations tolerant to water deficit

    E.V. Rodrigues, K.J. Damasceno-Silva, M.M. Rocha and E.A. Bastos

The purpose of this study was to identify parents and obtain segregating populations of cowpea (Vigna unguiculata L. Walp.) with the potential for tolerance to water deficit. A full diallel was performed with six cowpea genotypes, and two experiments were conducted in Teresina, PI, Brazil in 2011 to evaluate 30 F2 populations and their parents, one under water defic..

Simultaneous selection for cowpea (Vigna unguiculata L.) genotypes with adaptability and yield stability using mixed models

    F.E. Torres, P.E. Teodoro, E.V. Rodrigues, A. Santos, A.M. Corrêa, G. Ceccon

The aim of this study was to select erect cowpea (Vigna unguiculata L.) genotypes simultaneously for high adaptability, stability, and yield grain in Mato Grosso do Sul, Brazil using mixed models. We conducted six trials of different cowpea genotypes in 2005 and 2006 in Aquidauana, Chapadão do Sul, Dourados, and Primavera do Leste. The experimental design was.. Read More»

Selecting elephant grass families and progenies to produce bioenergy through mixed models (REML/BLUP)

    E.V. Rodrigues, R.F. Daher, A. dos Santos, M. Vivas, J.C. Machado, G. do A. Gravina, Y.P. de Souza, A.K. Vidal, A. dos S. Rocha and R.S. Freitas

Brazil has great potential to produce bioenergy since it is located in a tropical region that receives high incidence of solar energy and presents favorable climatic conditions for such purpose. However, the use of bioenergy in the country is below its productivity potential. The aim of the current study was to select full-sib progenies and families of elephant gras.. Read More»

Selection of Jatropha full-sib families based on genotypic adaptability and stability via mixed models

The objectives of this study were to estimate the genetic parameters for Jatropha full-sib families and to select superior genotypes based on grain yield, adaptability, and stability simultaneously to be used for cloning and crossings. Grain yield was evaluated in thirteen full-sib families in a randomized block design for 5 years. The harmonic mean of the relative .. Read More»
