Genome-wide association study of residual feed intake in Hereford cattle.

The aim of this study was to detect genomic regions and putative candidate genes associated with RFI in Hereford cattle by single-step GWAS (ssGWAS).

El objetivo de este trabajo es el estudio del efecto de la incorporación de información genómica sobre las predicciones del mérito genético para RFI.
The objective of this work was to estimate national genetic parameters of DM to develop a more precise evaluation and therefore a greater potential genetic progress of the breed.
El objetivo de este trabajo fue identificar regiones genómicas asociadas a la resistencia a NGI en ovinos Corriedale a través del estudio de asociación genómica en un solo paso (ssGWAS) del recuento de huevos por gramo en heces (HPG) utilizando 2 paneles de baja densidad y un panel comercial de mediana densidad.
The management of native grasslands during winter could have effects on both quantity and characteristics of spring grown forage.

ABSTRACT. - Insect epicuticle hydrocarbons (CHC) are known to be important determinants in the susceptibility degree of insects to fungal entomopathogens.
Alternate bearing in citrus trees has been extensively studied as a key feature for citrus growers. Although the genetic and the biochemical process occurring during alternate bearing has been studied extensively, there is a lack of information identifying the presence of metabolic indicators during ?on? and ?off? years. In citrus plants, leaves play a central role in the metabolic pathway triggering the flowering induction process.
Blossom blight and brown rot caused by Monilinia fructicola is the most important peach disease in Brazil. Genetic resistance is a control strategy that is gaining importance in breeding programs worldwide. This study aimed to identify genotypes with higher levels of blossom blight resistance to estimate the heritability of this character; study the frequency distribution in populations; and test the possibility of maternal effect. Blossom blight susceptibility was tested in reciprocal hybridizations seedlings, as well as their parents.
