ABSTRACT.- Eucalyptus tereticornis exhibits adaptation to a wide range of soils and environments, making it suitable for various protective and productive purposes throughout the territory of Uruguay. Due to the absence of a locally improved seed source, INIA began a tree breeding program in 2007 using genetic material from two sources: the natural distribution area of the species and local plantations. The performance of the genetic pool was evaluated at different sites over a nine-year growth period. The objectives of this study were to estimate genetic parameters (heritability, genetic correlations, and genotype-by-environment interaction) for growth and stem form traits and to estimate the genetic gains achievable through selection at different ages, in order to guide the breeding strategy for E. tereticornis. The genotype-environment interaction for volume and survival exhibited moderate to low levels, with Type B genetic correlations ranging from 0.68 to 0.82. The combined analysis of the trials revealed that heritability increased with the age of measurement for all traits, with values ranging from low to moderate for growth variables (0.04 - 0.23) and stem form (stem straightness and forking) showing low values (0.05 - 0.12). Genetic correlations between growth traits at different ages and volume at 9 years were positive and high (0.32 - 0.99), while the correlations between stem form (stem straightness and forking) and volume were low to moderate (0.30 - 0.56). The results obtained suggest that it is possible establish a single breeding unit and that through early selection, genetic gains can be maximized, evaluation costs reduced, and improved seed obtained in a shorter timeframe. © 2023, Universidad Austral de Chile.

Dada la inexistencia de una fuente de semilla localmente mejorada, en 2007 el INIA inició un programa de mejoramiento a partir de dos fuentes genéticas: el área de distribución natural y las plantaciones locales. Se evaluó el desempeño genético en diferentes sitios hasta el noveno año de crecimiento. Los objetivos de este estudio fueron: estimar los parámetros genéticos para las variables de crecimiento y forma del fuste, y estimar las ganancias genéticas esperadas mediante selección a diferentes edades. La interacción genotipo por medio ambiente para volumen y supervivencia fue de moderada a baja (correlaciones Tipo B entre 0,68 a 0,82). El análisis conjunto de los ensayos mostró que la heredabilidad aumentó con la edad de medición para todas las características, con valores bajos a moderados para las variables de crecimiento (0,04 a 0,23) y valores bajos (0,05 a 0,12) para la forma del fuste (rectitud y bifurcación). Las correlaciones genéticas entre las características de crecimiento a diferentes edades y el volumen a los 9 años fueron positivas y altas (0,32 a 0,99) mientras que las correlaciones entre la forma del fuste (rectitud y bifurcación) y el volumen fueron bajas a moderadas (0,30 a 0,56). Los resultados obtenidos sugieren que es posible manejar una sola unidad de mejoramiento y a través de la selección temprana maximizar las ganancias genéticas, reducir costos de evaluación y obtener semilla mejorada en menor tiempo.

The aim of this study was to assess the growth performance, forage intake and methane (CH4) emissions by beef cattle grazing under different spatiotemporal integrated crop-livestock systems (ICLSs). The experiment was conducted for two years (2017-2018 and 2018-2019) in warm season perennial pastures and cool season annual pastures grazed by beef steers. Three pesticide-free ICLS treatments - livestock-forestry (LF); crop-livestock (CL), and crop-livestock-forestry (CLF) - plus, a livestock control pesticide-free system (L) were conducted in randomized complete block design, with three replicates per treatment. © 2023 Elsevier Ltd |
