Abstract
Genetic resistance to basal stem rot (BSR) of oil palm is an important component of an integrated disease control strategy. Early detection of susceptibility or resistance level is essential for a breeding program and for the sustainability of this crop, particularly in Southeast Asia. A screening test for oil palm progenies was developed and validated using planting material from two private companies in Indonesia, PT PP London Sumatra Indonesia (Lonsum) and PT Socfin Indonesia (Socfindo) -. The first symptoms of the disease appeared between 8 and 10 weeks after inoculation of germinated seeds. The analysis of the crosses tested showed a positive correlation between 16 and 28 weeks, indicating that early detection is realistic and that there is minimal interaction of the susceptibility to the disease over time. The main objective of this paper is to highlight the efficiency and reproducibility of this early pre-nursery inoculation test to detect approximately 100 progeny per month. La resistencia genética a la Pudrición basal del tallo PBT) de la palma de aceite es un componente importante de una estrategia de control integrado de la enfermedad. La detección temprana del nivel de resistencia o susceptibilidad es fundamental para un programa de mejoramiento y para la sostenibilidad de este cultivo, particularmente en el sureste asiático. Una prueba de detección para progenies de palma de aceite se ha desarrollado y validado utilizando material de siembra de dos compañías privadas de Indonesia PT PP London Sumatra Indonesia (Lonsum) y PT Socfin Indonesia (Socfindo). Los primeros síntomas de la enfermedad aparecieron entre 8 y 10 semanas después de la inoculación de las semillas germinadas. Los análisis para cada cruce probado mostraron correlación positiva entre 16 y 28 semanas, indicando que la detección temprana es realista y que existe una interacción mínima de la susceptibilidad a la enfermedad con el tiempo. El objetivo principal de este documento es resaltar la eficiencia y la reproducibilidad de esta prueba temprana de inoculación pre-vivero que permite detectar ahora aproximadamente 100 progenies por mes.
