Boosting predictive ability of tropical maize hybrids via genotype-by-environment interaction under multivariate GBLUP models. Repositório Alice
KRAUSE, M. D.; DIAS, K. O. das G.; SANTOS, J. P. R. dos; OLIVEIRA, A. A. de; GUIMARAES, L. J. M.; PASTINA, M. M.; MARGARIDO, G. R. A.; GARCIA, A. A. F..
Genomic selection has been implemented in several plant and animal breeding programs and it has proven to improve efficiency and maximize genetic gains. Phenotypic data of grain yield was measured in 147 maize (Zea mays L.) singlecross hybrids at 12 environments. Single-cross hybrids genotypes were inferred based on their parents (inbred lines) via single nucleotide polymorphism (SNP) markers obtained from genotyping-by-sequencing (GBS). Factor analytic multiplicative genomic best linear unbiased prediction (GBLUP) models, in the framework of multienvironment trials, were used to predict grain yield performance of unobserved tropical maize single-cross hybrids. Predictions were performed for two situations: untested hybrids (CV1), and hybrids evaluated in...

Genomic prediction applied to high-biomass sorghum for bioenergy production. Repositório Alice
OLIVEIRA, A. A. de; PASTINA, M. M.; SOUZA, V. F. de; PARRELLA, R. A. da C.; NODA, R. W.; SIMEONE, M. L. F.; SCHAFFERT, R. E.; MAGALHAES, J. V. de; DAMASCENO, C. M. B.; MARGARIDO, G. R. A..
The increasing cost of energy and finite oil and gas reserves have created a need to develop alternative fuels from renewable sources. Due to its abiotic stress tolerance and annual cultivation, high-biomass sorghum (Sorghum bicolor L. Moench) shows potential as a bioenergy crop. Genomic selection is a useful tool for accelerating genetic gains and could restructure plant breeding programs by enabling early selection and reducing breeding cycle duration. This work aimed at predicting breeding values via genomic selection models for 200 sorghum genotypes comprising landrace accessions and breeding lines from biomass and saccharine groups. These genotypes were divided into two sub-panels, according to breeding purpose. We evaluated the following phenotypic...

In eukaryotes, DNA is organized along with histones in nucleoprotein complexes known as chromatin, which has nucleosomes as their fundamental unit. Chromatin Downloaded from https://academic.oup.com/jas/article-abstract/96/suppl_3/233/5235047 by Macquarie University user on 13 February 2019 234 J. Anim. Sci Vol. 96, Suppl. S3 exists in two forms: euchromatin, corresponding to a lightly condensed structure and an easily transcribed region, and heterochromatin, a highly condensed and transcriptionally silent region.

Linkage disequilibrium and population structure in wild and cultivated populations of rubber tree (Hevea brasiliensis). Repositório Alice
SOUZA, L. M. de; SANTOS, L. H. B. dos; ROSA, J. R. B. F.; SILVA, C. C. da; MANTELLO, C. C.; CONSON, A. R. O.; SCALOPPI JUNIOR, E. J.; FIALHO, J. de F.; MORAES, M. L. T. de; GONÇALVES, P. de S.; MARGARIDO, G. R. A.; GARCIA, A. A. F.; LE GUEN, V.; SOUZA, A. P. de.
Abstract: Among rubber tree species, which belong to the Hevea genus of the Euphorbiaceae family, Hevea brasiliensis (Willd. ex Adr.de Juss.) Muell. Arg. is the main commercial source of natural rubber production worldwide. Knowledge of the population structure and linkage disequilibrium (LD) of this species is essential for the efficient organization and exploitation of genetic resources. Here, we obtained single-nucleotide polymorphisms (SNPs) using a genotyping-by-sequencing (GBS) approach and then employed the SNPs for the following objectives: (i) to identify the positions of SNPs on a genetic map of a segregating mapping population, (ii) to evaluate the population structure of a germplasm collection, and (iii) to detect patterns of LD decay among...

Single nucleotide polymorphism calling and imputation strategies for cost-effective genotyping in a tropical maize breeding program. Repositório Alice
OLIVEIRA, A. A. de; GUIMARAES, L. J. M.; GUIMARÃES, C. T.; GUIMARAES, P. E. de O.; PINTO, M. de O.; PASTINA, M. M.; MARGARIDO, G. R. A..
Genotyping-by-sequencing (GBS) datasets typically feature high rates of missingness and heterozygote undercalling, prompting the use of data imputation. We compared the accuracy of four imputation methods?NPUTE, Beagle, knearest neighbors imputation (KNNI), and fast inbreed line library imputation (FILLIN)?using GBS data of maize (Zea mays L.) inbred lines, genotyped using different multiplexing levels. Two strategies for SNP-calling and genotype imputation were evaluated. First, only lines genotyped through 96-plex were used for single nucleotide polymorphism (SNP) discovery, whereas both 96- and 384-plex were simultaneously used in the second strategy. In the first genotype imputation strategy, only the 96-plex lines were imputed, then the remaining...

Studying the genetic basis of drought tolerance in sorghum by managed stress trials and adjustments for phenological and plant height differences. Repositório Alice
SABADIN, P. K.; MALOSETTI, M.; BOER, M. P.; TARDIN, F. D.; SANTOS, F. G.; GUIMARAES, C. T.; GOMIDE, R. L.; ANDRADE, C. L. T.; ALBUQUERQUE, P. E. P.; CANIATO, F. F.; MOLLINARI, M.; MARGARIDO, G. R. A.; OLIVEIRA, B. F.; SCHAFFERT, R. E.; GARCIA, A. A. F.; EEUWIJK, F. A. van; MAGALHAES, J. V..
Managed environments in the form of well watered and water stressed trials were performed to study the genetic basis of grain yield and stay green in sorghum with the objective of validating previously detected QTL. As variations in phenology and plant height may influence QTL detection for the target traits, QTL for flowering time and plant height were introduced as cofactors in QTL analyses for yield and stay green. All but one of the flowering time QTL were detected near yield and stay green QTL. Similar co-localization was observed for two plant height QTL. QTL analysis for yield, using flowering time/plant height cofactors, led to yield QTL on chromosomes 2, 3, 6, 8 and 10. For stay green, QTL on chromosomes 3, 4, 8 and 10 were not related to...
