Background: The advent of high-throughput genotyping technologies coupled to genomic prediction methods established a new paradigm to integrate genomics and breeding. We carried out whole-genome prediction and contrasted it to a genome-wide association study (GWAS) for growth traits in breeding populations of Eucalyptus benthamii (n =505) and Eucalyptus pellita (n =732). Both species are of increasing commercial interest for the development of germplasm adapted to environmental stresses. Results: Predictive ability reached 0.16 in E. benthamii and 0.44 in E. pellita for diameter growth. Predictive abilities using either Genomic BLUP or different Bayesian methods were similar, suggesting that growth adequately fits the infinitesimal model. Genomic prediction models using ~5000?10,000 SNPs provided predictive abilities equivalent to using all 13,787 and 19,506 SNPs genotyped in the E. benthamii and E. pellita populations, respectively. No difference was detected in predictive ability when different sets of SNPs were utilized, based on position (equidistantly genome-wide, inside genes, linkage disequilibrium pruned or on single chromosomes), as long as the total number of SNPs used was above ~5000. Predictive abilities obtained by removing relatedness between training and validation sets fell near zero for E. benthamii and were halved for E. pellita. These results corroborate the current view that relatedness is the main driver of genomic prediction, although some short-range historical linkage disequilibrium (LD) was likely captured for E. pellita. A GWAS identified only one significant association for volume growth in E. pellita, illustrating the fact that while genome-wide regression is able to account for large proportions of the heritability, very little or none of it is captured into significant associations using GWAS in breeding populations of the size evaluated in this study. Conclusions: This study provides further experimental data supporting positive prospects of using genome-wide data to capture large proportions of trait heritability and predict growth traits in trees with accuracies equal or better than those attainable by phenotypic selection. Additionally, our results document the superiority of the whole-genome regression approach in accounting for large proportions of the heritability of complex traits such as growth in contrast to the limited value of the local GWAS approach toward breeding applications in forest trees.

Plantas de soja das cultivares 'Santa Rosa', 'Hill', 'UFV-1' e 'Campos Gerais' foram inoculadas com tres estirpes do virus do mosaico comum da soja. Setenta dias apos a emergencia, procederam-se as avaliacoes de peso total, peso seco de nodulos e teor de clorofila nas folhas. Com excecao de 'Campos Gerais', que mostrou reducao do crescimento e do peso de nodulos com a estirpe MS-1, a qual e suscetivel, as demais cultivares sofreram a mesma influencia negativa de todas as estirpes usadas. Nao houve diferencas de efeitos das estirpes sobre a cultivar 'Santa Rosa'. Todas as plantas infectadas apresentaram reducao no teor de clorofila sendo as maiores reducoes induzidas pelas estirpes MS-1. Nas cultivares utilizadas, as correlacoes simples entre o peso seco de plantas e o teor de clorofila foram altamente significativas. |
