Correlation among traits as criterion of cotton genotypes indirect selection
Authors: MC Reis, DBO Cardoso, EG Silva J�ºnior, BC Gomes, LTG Pereira, DA Gomes and LB Sousa.
The cotton crop has notable importance for Brazilian and worldwide economy. Relationships knowledge among characters allows developing alternatives that increase the genetic progress with simultaneous selection of several traits. The use of correlation estimates for use in indirect selection helps the breeder in the selection .. Read More»

Evolution of the genus Mimivirus based on translation protein homology and its implication in the tree of life
Authors: V.M. Marcelino, M.V.P.C. Espinola, V. Serrano-Solis and S.T. Farias
The natural history of mimiviruses (i.e., viruses that are members of the Mimivirus genus) is a challenge for modern biology. A new domain of life to include these organisms has been proposed from analysis of gene conservation. We analyzed the evolutionary relationship of proteins involved in the translation system, and our da.. Read More»

Minimum number of measurements for evaluating Bertholletia excelsa
Authors: A.B. Baldoni, H. Tonini, F.D. Tardin, S.C.C. Botelho and P.E. Teodoro
Repeatability studies on fruit species are of great importance to identify the minimum number of measurements necessary to accurately select superior genotypes. This study aimed to identify the most efficient method to estimate the repeatability coefficient (r) and predict the minimum number of measurements needed for a more a.. Read More»

Iron excess in rice: from phenotypic changes to functional genomics of WRKY transcription factors
Authors: V.E. Viana, N. Marini, T. Finatto, I. Ezquer, C. Busanello, R.S. dos Santos, C. Pegoraro, L. Colombo and A. Costa de Oliveira
Iron (Fe) is an essential microelement for all living organisms playing important roles in several metabolic reactions. Rice (Oryza sativa L.) is commonly cultivated in paddy fields, where Fe goes through a reduction reaction from Fe3+ to Fe2+. Since Fe2+ is more soluble, it can reach toxic levels inside plant cells, constitut.. Read More»

Diallel crosses for resistance to Macrophomina phaseolina and Thanatephorus cucumeris on cowpea
Authors: L.R.L. Lima, K.J. Damasceno-Silva, M.A. Noronha, D.A. Schurt and M.M. Rocha
This study aimed at identifying and selecting through partial diallel analysis, segregating populations of cowpea resistant to Macrophomina phaseolina and Thanatephorus cucumeris, based on the evaluation of general (GCA) and specific combining ability (SCA), involved in the genetic control of resistance. For this reason, 19 gr.. Read More»

Diversity among elephant grass genotypes using Bayesian multi-trait model
Authors: D.A. Rossi, R.F. Daher, T.C. Barb�©, R.S.N. Lima, A.F. Costa, L.P. Ribeiro, P.E. Teodoro and L.L. Bhering
Elephant grass is a perennial tropical grass with great potential for energy generation from biomass. The objective of this study was to estimate the genetic diversity among elephant grass accessions based on morpho-agronomic and biomass quality traits and to identify promising genotypes for obtaining hybrids with high energet..

Estimates of genetics and phenotypics parameters for the yield and quality of soybean seeds
Authors: E.V. Zambiazzi, A.T. Bruzi, S.R. Guilherme, D.R. Pereira, J.G. Lima, A.M. Zuffo, F. O. Ribeiro, A.E.S. Mendes, S.H.M. Godinho and M.L.M. Carvalho
Estimating genotype x environment (GxE) parameters for quality and yield in soybean seed grown in different environments in Minas Gerais State was the goal of this study, as well as to evaluate interaction effects of GxE for soybean seeds yield and quality. Seeds were produced in three locations in Minas Gerais State (Lavras, .. Read More»

Molecular identification of variety purity in a cotton hybrid with unknown parentage using DNA-SSR markers
Authors: X.Q. Fu, F.X. Yang, X.K. Lu, X.G. Wang, B.X. Yang, F.J. Liu, Y. Liu and J. Peng
Molecular identification of hybrid purity is difficult in regional trials of cotton varieties and hybrid trials. In particular, the molecular detection of hybrid purity has not yet been reported in the case of unknown parentage. In this study, we screened 5000 pairs of primers and chose 17 pairs of core simple sequence repeat .. Read More»

Cotton genotypes selection through artificial neural networks
Authors: E.G. Silva J�ºnior, D.B.O. Cardoso, M.C. Reis, A.F.O. Nascimento, D.I. Bortolin, M.R. Martins and L.B. Sousa
Breeding programs currently use statistical analysis to assist in the identification of superior genotypes at various stages of a cultivar’s development. Differently from these analyses, the computational intelligence approach has been little explored in genetic improvement of cotton. Thus, this study was carried out wit.. Read More»

In order to obtain the certificate of cultivar protection, it is necessary to prove its distinctiveness, homogeneity, and stability. Currently, there are 37 descriptors for differentiating soybeans cultivars. However, they are still not enough and, as a result, it is necessary to create, identify, and evaluate new descriptors...
