SOUZA, N. O. de; ALVES, R. S.; TEODORO, P. E.; SILVA, L. A. da; TARDIN, F. D.; BALDONI, A. B.; RESENDE, M. D. V. de; BHERING, L. L.To increase yield, breeding programs must search for innovative and efficient methodologies for the development and selection of superior genotypes. Therefore, this study aimed to compare the single- and multiple-trait best linear unbiased prediction (BLUP) in genetic selection of parents and hybrids of grain sorghum. For this, an experiment conducted in alpha-lattice design with two replications was used. Flow...
Adaptability and stability of cotton genotypes regarding fiber yield and qualit...
TEODORO, P. E.; FARIAS, F. J. C.; CARVALHO, L. P. de; RIBEIRO, L. P.; NASCIMENTO, M.; AZEVEDO, C. F.; CRUZ, C. D.; BHERING, L. L.The performance of textile processes and the quality of the products depends on the several cotton (Gossypium hirsutum L.) fiber quality traits, such as micronaire index, fiber length, and fiber strength. This research aims to recommend cotton genotypes for the Brazilian Cerrado based on fiber yield and fiber quality traits. Nineteen cotton cultivar variety trials were performed in the 2013?2014 and 2014?2015 c...
Environmental stratification in the brazilian Cerrado on the yield and fiber qu...
COTRIM, M. F.; FARIAS, F. J. C.; CARVALHO, L. P. de; TEODORO, L. P. R.; BHERING, L. L.; TEODORO, P. E.Environmental stratification studies are important for the plant breeding, since they allow to adequately plan the experimental network. The objective of this work was to identify similar environments for cotton cultivation in the Brazilian Cerrado regarding yield and fiber quality. Nineteen field studies were carried out in a randomized complete block design with twelve genotypes and four replicates. Agronomic...
Selection and genetic parameters for interpopulation hybrids between kouilou an...
CARVALHO, H. F.; SILVA, F. L. da; RESENDE, M. D. V. de; BHERING, L. L.Selection of hybrid coffee plants coming from crosses between divergent populations is particularly relevant for the success of breeding programs. This study aimed to outline the best selection strategy in a hybrid population of Coffea canephora var. kouilou and robusta by estimating intrapopulation genetic parameters. Twenty full-sib progenies obtained by North Caroline II were installed in a randomized comple...

Interrelations between agronomic and technological fiber traits in upland cotton.
TEODORO, P. E.; CARVALHO, L. P. de; RODRIGUES, J. I. S; FARIAS, F. J. C.; CARNEIRO, P. C. S.; BHERING, L. L.Fiber length stands out among technological traits as one that still needs to be improved in cotton. Thus, the objectives of this work were to quantify the interrelations between agronomic and technological fiber traits and to identify traits that could be used for the indirect selection of cotton genotypes with longer fiber lengths. Agronomic and technological traits were evaluated in 36 elite lines of cotton ...
Estimates of repeatability coefficients and the number of the optimum measure t...
SANCHÉZ, C. F. B.; ALVES, R. S.; GARCIA, A. d. P.; TEODORO, P. E.; PEIXOTO, L. A.; SILVA, L. A.; BHERING, L. L.; RESENDE, M. D. V. deThe aim of this study was to evaluate repeated measures over the years to estimate repeatability coefficient and the number of the optimum measure to select superior genotypes in Annona muricata L. The fruit production was evaluated over 16 years in 71 genotypes without an experimental design. The estimation of variance components and the prediction of the permanent phenotypic value were performed using REML/BL...
Genetic divergence of strawberry cultivars under different managements.
COSTA, A. F. da; RIBEIRO, L. P.; TEODORO, P. E.; BHERING, L. L.; TARDIN, F. D.; FORNAZIER, M. J.; COSTA, H.; MARTINS, D. dos S.; ZANUNCIO JUNIOR, J. S.Developing strawberry cultivars that can be grown on a large scale, it is necessary to gather desirable characteristics such as: tolerance to Tetranychus urticae, high fruit yield and wide adaptability to several cropping managements. Therefore, our objective was to study the genetic diversity among 13 strawberry cultivars under different managements and to recommend promising crosses to obtain segreganting pop...
Evaluation of genotype x environment interactions in cotton using the method pr...
ALVES, R. S.; TEODORO, P. E.; FARIAS, F. C.; FARIAS, F. J. C.; CARVALHO, L. P. de; RODRIGUES, J. I. S.; BHERING, L. L.; RESENDE, M. D. V. deCotton produces one of the most important textile fibers of the world and has great relevance in the world economy. It is an economically important crop in Brazil, which is the world?s fifth largest producer. However, studies evaluating the genotype x environment (G x E) interactions in cotton are scarce in this country. Therefore, the goal of this study was to evaluate the G x E interactions in two important t...
Molecular analysis of genetic diversity among vine accessions using DNA markers.
COSTA, A. F. da; TEODORO, P. E.; BHERING, L. L.; TARDIN, F. D.; DAHER, R. F.; CAMPOS, W. F.; VIANA, A. P.; PEREIRA, M. G.Viticulture presents a number of economic and social advantages, such as increasing employment levels and fixing the labor force in rural areas. With the aim of initiating a program of genetic improvement in grapevine from the State University of the state of Rio de Janeiro North Darcy Ribeiro, genetic diversity between 40 genotypes (varieties, rootstock, and species of different subgenera) was evaluated using ...
