ABSTRACT.- The aim was to evaluate the association between growth, carcass and visual scores traits with precocious calving in Nellore cattle. Birth weight (BW), weight at 120, 210, 365 and 450 days of age, pre and post-weaning average daily gain, rib eye area, backfat thickness (BF), rump fat thickness and visual scores obtained at 18 months were used for the analysis. Records from 700 females born between 2009 and 2015, exposed to mating starting at 11 months of age were analyzed. Discriminant analyzes were performed with the software Statistica. BW and BF showed the highest (P>0.01) discrimination value for early heifer pregnancy (EP). Extreme intrauterine growth retardation can result in slower growth, which reflects in the worst reproductive performance, confirmed by the variation in BW between precocious and conventional heifers. The results also demonstrate that the level of body fat affects begin of puberty. Bone structure, musculature, depth, tail insertion and rump scores presented the highest discrimination value for EP. These traits can be used as selection tools to improve sexual precocity in female Nellore cattle. The results obtained in this study would support farmers to guide the heifer management and decisions in order to enhance the EP. |

ABSTRACT.
The strawberry fruit production in Uruguay is mainly dedicated to the internal fresh market but there are some experiences of exportation to regional and off shore countries. The crop is done in the annual hill system without the use of methyl bromide and the mean yield is about 40 t/ha. Main crop areas are located in the Northwest (Salto, 31°S) and in the South (San José, 34°S). The winter and early spring fruit production is obtained in the Northwest area with crops under low and high tunnels using short day cultivars like 'INIA Yvahé', 'INIA Arazá' and 'Earlibrite'. Transplants are locally produced in this area in greenhouse nurseries. The Southern area produces fruit in the spring with open field crops using short day cultivars like 'Camarosa' and 'Camino Real' and in the summer with day neutral cultivars like 'Aromas' and 'Seascape'. Frigo-transplants of the introduced cultivars are imported from Spain and USA. Problems of adaptation to the climatic and agronomic conditions of Uruguay have been observed in the introduced cultivars. This was translated to low yields, low fruit quality and susceptibility to diseases prevalent in the regions of production. For that reason the Strawberry Breeding Project of INIA Uruguay aims to obtain cultivars adapted to the different environments of the country. The products of this breeding project, initiated in 1992, are the cultivars 'INIA Arazá', released in 2002, with high early yield and resistance to anthracnose; 'INIA Yvahé', released in 2004, with early yield and excellent flavor, resistant to anthracnose; 'INIA Guenoa', released in 2007, with high yield, excellent fruit quality, better adapted to high tunnels and resistant to powdery mildew; 'INIA Yvapitá', to be released in 2008 for open field crop, recommended for organic production and processing, resistant to several soil, foliage and fruit diseases. New selections are in different stages of evaluation. A method of propagation was adjusted to ensure appropriated quality of the transplants. MenosABSTRACT.
