Abstract
El raps canola (Brassica napus L.) representa una alternativa para diversificar la producción adaptándose a las condiciones de suelo y clima de la zona centro sur del país. Se estableció un ensayo para evaluar el comportamiento de cinco genotipos de raps de primavera en dos tipos de suelos de la región de La Araucanía (Andisol y Ultisol). El modelo experimental correspondió a un factorial 5x2 que consistió en cinco genotipos y dos tipos de suelo. Las variables a evaluar en el estudio fueron rendimiento del grano y contenido de aceite de la semilla. Los resultados mostraron efectos significativos de la interacción genotipo x ambiente (suelo) para estos parámetros. El mayor rendimiento en el Ultisol correspondió a los genotipos ‘Ability’ y ‘Sonja’, mientras en el Andisol, correspondió a los genotipos ‘Gladiador’, ‘Salsa’ y ‘Hyola 618’. El mayor porcentaje de aceite en el grano correspondió a los genotipos ‘Ability’ y ‘Sonja’, en el Ultisol; y a ‘Gladiador’, ‘Salsa’ y ‘Hyola 618’, en el Andisol. Los resultados del análisis combinado de varianza para el rendimiento por planta de los cinco genotipos de raps y los dos ambientes (tipos de suelo) confirmaron la existencia de efecto de interacción genotipo x suelo.
The rapeseed (Brassica napus L.) represent an alternative to diversify the production adapting to the soil and climate conditions of the South Central zone of the country. The purpose this work was studied the effects of the interaction of five genotypes of spring rapeseed and two typical soils representative of La Araucanía Region, Andisol and Ultisol. The experimental model corresponded to 5x2 factorial design, which consisted in five genotypes and two types of soil. Variables to be evaluated in the study were: grain yield and oil content of the seed. The results showed genotype x environment (soil) significant interaction effects for grain yield and percentage of seed oil. The highest yield in Ultisol corresponded to the genotype ‘Ability’ and ‘Sonja’, while Andisol were achieved by ‘Gladiador’, ‘Salsa’ and ‘Hyola 618’ genotypes. The highest percentage of oil in the grain corresponded to ‘Ability’ and’ Sonja’, in the Ultisol and ‘Gladiador’, ‘Salsa’ and ‘Hyola 618’ genotypes in the Andisol. The results of the combined analysis of variance for yield per plant of five rapeseed genotypes and two environments (soil types), confirmed the existence of genotype x soil interaction effect.
