| dc.description | The success of breeding programs depends on the available genetic variability and the adequate selection of parents to produce seeds that generate added value to the developed cultivars that solve limiting problems of the crops. The determination of genetic gain is a powerful tool to advance the selection of outstanding progenitors that are subsequently used to obtain improved cultivars for traits of interest. With the main objective of calculating the genetic gain in different cycles, this research evaluated the yield, vegetative parameters, and oil production components in two oil palm populations identified as C0-Monterrey and C1-Vizcaina. The analysis was carried out using the analysis of variance. Genetic variation and heritability coefficients for all the evaluated traits were also calculated to obtain the components of phenotypic, genotypic, and environmental variation. Genetic gains (Δg) were more representative in the yield traits of fresh fruit bunches, with 19 %, for the number of bunches per plant, with a Δg of 18.7 %, and for the oil to bunch with a Δg of 6 %. Low environmental influences were observed in the phenotypic variation for the different traits evaluated. Finally, high heritability values were observed for genetic traits such as height increase, with 93 %, and average bunch weight, with 85 %. | en-US |
| dc.description | El éxito de los programas de mejoramiento genético depende de la variabilidad genética disponible y de la adecuada selección de los parentales para producir semillas que generen valor agregado a los cultivares desarrollados y que contribuyan a resolver problemas limitantes de los cultivos. La determinación de la ganancia genética es una herramienta fundamental para avanzar en la selección de progenitores sobresalientes que posteriormente se utilizan para obtener cultivares mejorados para los caracteres de interés. Con el objetivo principal de calcular la ganancia genética en diferentes ciclos, esta investigación evaluó el rendimiento, los parámetros vegetativos y los componentes de la producción de aceite en dos poblaciones de palma de aceite identificadas como C0-Monterrey y C1-Vizcaína. El análisis se llevó a cabo mediante análisis de varianza. También se calcularon los coeficientes de variación genética y heredabilidad para todos los caracteres evaluados, con el fin de estimar los componentes de la variación fenotípica, genotípica y ambiental. Las ganancias genéticas (Δg) fueron más representativas en los rasgos de rendimiento de los racimos de fruta fresca, con 19 %; en el número de racimos por planta, con una Δg de 18,7 %, y en la relación aceite/racimo, con una Δg de 6 %. Se observaron bajas influencias ambientales en la variación fenotípica de los diferentes caracteres evaluados. Por último, se registraron altos valores de heredabilidad para caracteres genéticos como el aumento de altura, con un 93 %, y el peso promedio del racimo, con un 85 %. | es-ES |
