RESUMEN.
El portainjerto en frutales juega un papel importante en el control de vigor de la planta, en la precocidad de producción y en la adaptación a ciertas condiciones de suelo, entre otros. Desde 1999, el Programa de Investigación en Producción Frutícola de INIA en Uruguay, está evaluando diversas combinaciones portainjerto- variedad de peral, con el objetivo de seleccionar aquella que ofrezca mayor potencial agronómico, permitiendo mayores producciones de calidad comercial, en el ambiente templado-húmedo de la región. Hasta el momento, es posible observar comportamientos interesantes de algunas de las combinaciones evaluadas. Esto ofrecerá al sector frutícola, importante información de algunos portainjertos adaptados para el desarrollo de una de las especies con potencial de exportación en el país.

ABSTRACT.
Rootstocks in fruit trees play an important role in the plant vigor control, in production precociousness and plant adaptation to soil conditions; among others. Since 1999, INIA's Fruit Research Program of Uruguay is evaluating different pear variety-rootstock combinations, in order to select one with greater agronomic potential, achieving greater
productions of commercial quality; in the temperate and humid environment of the region. Up to date, it's possible to observe promising performances in sorne combinations evaluated. This will provide to the fruit industry, valuable information of adapted rootstocks for the development of one of the species with export potential for the country. MenosRESUMEN.

ABSTRACT: The aim of this study was to estimate genetic parameters and to identify genomic regions associated with the calving ease (CE) in precocious Nellore heifers. A total of 1,277 CE phenotypes were collected and scored into two categories: i- non assisted calving, categorized as success (1) and ii- assisted calving where heifers required any form of assistance or intervention to give birth, categorized as failure (2). A pedigree structure containing the identification of the animal's sire and dam was used, with the relationship matrix comprising a total of 6,511
animals. Genotypic data from 1,201 animals were obtained using low-density panel (Clarifide Nelore 3.1) encompassing over 29,001 single nucleotide polymorphisms (SNP) markers. A threshold sire-maternal grandsire model (S-MGS) was used to estimate the genetic parameters, which included sire, maternal grandsire and residual effects as random effects and the fixed effects of contemporary groups (farm and year of calving, sex) and birth weight of the calf as covariable (linear effect). Genomic breeding values were estimated using an animal model with the direct and maternal genetic variances which were previously obtained by means of a S-MGS threshold model. The direct and maternal heritability estimates for CE were obtained considering the covariance of direct and maternal effects fixed as zero. Regions that accounted for more than 0.5% of the additive genetic variance were used. The direct and maternal heritability estimates for CE were low (0.18) and moderate (0.39)
respectively, indicating that genetic progress for this trait is feasible, and so, it would respond favorably to direct selection. Genes identified within the significant windows, such as CA8, FAM110B, TOX, ARID1A, RBM15, HSF1 and PLAG1 were found to be related with maternal and direct effects on CE. Gene enrichment analysis revealed processes that might directly influence fetal processes involved in female pregnancy and stress response. These results should help to better understand the genetic and physiological mechanisms regulating placenta development and fetal development, and this information might be useful for future genomic studies in Nellore cattle.
