Conteúdo: |
Um dos recursos de que hoje dispoe os lavradores de todo o mundo para aumentar e assegurar o rendimento de suas lavouras, quer do ponto de vista quantitativo como qualitativo, e o uso dos chamados defensivos agricolas ou pesticidas, sem duvida um aliado importantissimo na luta contra a ameaca de fome que assola o mundo. E claro, ha outros metodos de controle mais permanentes, mas, no geral, eles sao de implantacao deorada. E logico que eles sao benvindos, mas enquanto eles nao chrgam, as pragas e doencas continuam a devastar as plantacoes e estao a exigir providencias rapidas e seguras; e os pesticidas, uma vez usados com responsabilidade, de modo correto, sao, no momento, essas providencias rapidas e seguras, de emergencia. Esperamos que no futuro outros metodos de controle possam dar uma contribuicao mais efetiva no controle de pragas e doencas das plantas cultivadas. |

Genomic prediction integrates statistical, genomic, and computational tools to improve the estimation of breeding values and increase genetic gain. Due to the broad diversity in mating systems, breeding schemes, propagation methods, and unit of selection, no universal genomic prediction approach can be applied in all crops. In a genome-wide family prediction (GWFP) approach, the family is the basic unit of selection. We tested GWFP in two loblolly pine (Pinus taeda L.) datasets: a breeding population composed of 63 full-sib families (5?20 individuals per family), and a simulated population with the same pedigree structure. In both populations, phenotypic and genomic data was pooled at the family level in silico. Marker effects were estimated to compute genomic estimated breeding values (GEBV) at the individual and family (GWFP) levels. Less than six individuals per family produced inaccurate estimates of family phenotypic performance and allele frequency. Tested across different scenarios, GWFP predictive ability was higher than those for GEBV in both populations. Validation sets composed of families with similar phenotypic mean and variance as the training population yielded predictions consistently higher and more accurate than other validation sets. Results revealed potential for applying GWFP in breeding programs whose selection unit are family, and for systems where family can serve as training sets. The GWFP approach is well suited for crops that are routinely genotyped and phenotyped at the plot-level, but it can be extended to other breeding programs. Higher predictive ability obtained with GWFP would motivate the application of genomic prediction in these situations.
