RESUMEN.
El sistema de producción de frutilla en el litoral norte de Uruguay está basado en micro y macrotúneles, con el objetivo de producir fruta durante otoño, invierno y primavera. El objetivo del programa de mejoramiento de INIA es contar con variedades adaptadas a las condiciones ambientales, resistentes a enfermedades y plagas, de alta calidad, sabor y vida postcosecha. El objetivo del trabajo consistió en la evaluación de calidad de fruta de seis cultivares de frutilla (INIA Yvahé, INIA Guenoa, Yurí, Earlibrite, SGK50.4 y SGJ37.2) durante la estación productiva y la evaluación sensorial de los tres cultivares INIA disponibles en el mercado. Se trabajó con tres repeticiones por cultivar, evaluando calidad externa e interna en cosecha para cada fecha considerada (junio, setiembre y octubre). Se seleccionaron tres cultivares (INIA Yvahé, INIA Guenoa, Yurí) para su evaluación sensorial con consumidores en la cosecha de octubre. Yurí destacó por su calidad de fruta, siendo el cultivar más firme en todas las fechas de cosecha (20-55%). Respecto a la evaluación sensorial, los tres cultivares alcanzaron altos puntajes de aceptabilidad global. De acuerdo a la percepción de los consumidores, existieron claras diferencias en las características sensoriales de los cultivares, principalmente en su dulzor, acidez, tamaño, firmeza y forma. Yurí fue percibido por los consumidores como más dulce y firme que INIA Guenoa e INIA Yvahé. Es posible concluir que existen diferencias significativas en la calidad de fruta obtenida en función de la época de cosecha y que los cultivares evaluados tienen amplia aceptación por los consumidores uruguayos.
SUMMARY.
The strawberry production system in the north of Uruguay is primarily done under low and high tunnels with the objective of
obtaining fruit during autumn, winter and spring. The aim of INIA?s breeding program is to obtain varieties adapted to local
environmental conditions, resistant to pests and diseases, with high fruit quality, good flavour and extended postharvest life. The
aim of this work was to evaluate fruit quality of six strawberry cultivars (INIA Yvahé, INIA Guenoa, Yurí, Earlibrite, SGK50.4 and
SGJ37.2) throughout harvest season and the sensory evaluation of the three INIA cultivars available in the market. Three
replicates per cultivar were analyzed at harvest for external and internal quality for each date considered (June, September and
October). Three cultivars were selected (INIA Yvahé, INIA Guenoa, Yurí) for sensory evaluation with consumers in the
October harvest. Yurí showed the highest fruit quality, being the cultivar with the higher fruit firmness throughout harvest season
(20-55 % ). The three selected cultivars showed high consumer overall and flavour acceptability scores. According to
consumer?s perception, clear differences on sensory attributes existed between cultivars, mainly in sweetness, acidity, size,
firmness and shape. Yurí was perceived by consumers sweeter and firmer than INIA Guenoa and INIA Yvahé. It is possible to conclude that fruit quality is dependent on harvest date and that the cultivars considered were highly accepted by Uruguayan
consumers. MenosRESUMEN.

ABSTRACT.
Oxidative stress occurs when oxidant production exceeds the antioxidant capacity to detoxify the reactive intermediates or to repair the resulting damage. Feed efficiency has been associated with mitochondrial function due to its impact on cell energy metabolism. However, mitochondria are also recognized as a major source of oxidants. The aim of this study was to determine lipid and protein oxidative stress markers, and gene and protein expression as well as activity of antioxidant enzymes in the liver of steers of divergent residual feed intake (RFI) phenotypes. Hereford steers (n = 111) were evaluated in post-weaning 70 days standard test for RFI. Eighteen steers exhibiting the greatest (n = 9; high-RFI) and the lowest (n = 9; low-RFI) RFI values were selected for this study. After the test, steers were managed together under grazing conditions until slaughter when they reached the slaughter body weight. At slaughter, hepatic samples were obtained, were snap-frozen in liquid nitrogen and stored at −80°C until analyses. Hepatic thiobarbituric acid reactive species and protein carbonyls were greater (P = 0.05) and hepatic 4-hydroxynonenal protein adducts tended (P = 0.10) to be greater for high- than low-RFI steers. Hepatic gene expression glutathione peroxidase 4, glutamate?cysteine ligase catalytic subunit and peroxiredoxin 5 mRNA was greater (P ≤ 0.05) and glutathione peroxidase 3 mRNA tended (P = 0.10) to be greater in low- than high-RFI steers. Hepatic protein expression and enzyme activity of manganese superoxide dismutase and glutathione peroxidase enzyme activity tended (P ≤ 0.10) to be greater for low- than high-RFI steers. High-efficiency steers (low-RFI) probably had better hepatic oxidative status which was strongly associated with greater antioxidant ability near to the oxidant production site and, therefore, reduced oxidative stress of the liver. Decreased hepatic oxidative stress would reduce maintenance requirements due to a lower protein and lipid turnover and better efficiency in the use of energy.
