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»

Genetic divergence in the common bean (Phaseolus vulgaris L.) in the Cerrado-Pantanal ecotone

    F.A. da Silva, A.M. Corrêa, P.E. Teodoro, K.V. Lopes, C.C.G. Corrêa

Evaluating genetic diversity among genotypes is important for providing parameters for the identification of superior genotypes, because the choice of parents that form segregating populations is crucial. Our objectives were to i) evaluate agronomic performance; ii) compare clustering methods; iii) ascertain the relative contributions of the variables evaluated; and.. Read More»

Biplot analysis of strawberry genotypes recommended for the State of Espírito Santo

    A.F. Costa, P.E. Teodoro, L.L. Bhering, N.R. Leal, F.D. Tardin and R.F. Daher

Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, and helps provide specific recommendations..

Biplot analysis of phenotypic stability in upland cotton genotypes in Mato Grosso

    F.J.C. Farias, L.P. Carvalho, J.L. Silva Filho and P.E. Teodoro

Seed cotton yield is a trait governed by multiple genes that cause changes in the performance of genotypes depending on the cultivation environment. Breeding programs examine the genotype x environment interaction (GE) using precise statistical methods, such as AMMI (additive main effects and multiplicative interaction) and GGE biplot (genotype main effects + genoty..

Measurements of experimental precision for trials with cowpea (Vigna unguiculata L. Walp.) genotypes

    P.E. Teodoro, F.E. Torres, A.D. Santos, A.M. Corrêa, M. Nascimento, L.M.A. Barroso4 and G. Ceccon

The aim of this study was to evaluate the suitability of statistics as experimental precision degree measures for trials with cowpea (Vigna unguiculata L. Walp.) genotypes. Cowpea genotype yields were evaluated in 29 trials conducted in Brazil between 2005 and 2012. The genotypes were evaluated with a randomized block design with four replications. Ten statistics th..

Genetic diversity between and within half-sib families of Brazil nut tree (Bertholletia excelsa Bonpl.) originating from native forest of the Brazilian Amazon

Brazil nut tree is a species of economic importance for the Amazon region, known for the commercialization of its almonds. The objective of this work was to study the genetic diversity among half-sib progenies from different Brazil nut trees present in native forest in the municipality of Itaúba, MT, belonging to the Brazilian Amazon. In a native forest area .. 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 ..

Assessment of genetic divergence among coffee genotypes by Ward-MLM procedure in association with mixed models

    W.P. Rodrigues, H.D. Vieira, P.E. Teodoro F.L. Partelli and D.H.S.G. Barbosa

Mixed linear models have been used for the analysis of the genetic diversity and provided further accurate results in crops such as eucalyptus, castor, and sugarcane. However, to date, research that combined this analysis with Ward-MLM procedure has not been reported. Therefore, the aim of the present study was to identify divergent coffee genotypes by Ward-MLM proc.. Read More»

Adaptability and phenotypic stability of common bean genotypes through Bayesian inference

    A.M. Corrêa, P.E. Teodoro, M.C. Gonçalves, L.M.A. Barroso,M. Nascimento, A. Santos and F.E. Torres

This study used Bayesian inference to investigate the genotype x environment interaction in common bean grown in Mato Grosso do Sul State, and it 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 13 common bean genotypes was assessed. To represen.. Read More»
