| description | Assimilate partitioning into reproductive structures is a relevant physiological feature in increasing peanut yield, and its analysis through the source-sink relationship is an important contribution to genetic improvement and crop management. The objective was to analyze the source-sink relationship of runner-type cultivars grown in Argentina. Two field experiments were performed, Exp1 consisted in the analysis of the cultivar Granoleico in three sowing dates during 2009-2010 and 2010-2011. In Exp2, six runner-type cultivars (Florunner, Florman, Manigran, Asem-485, Pepe-Asem and Granoleico) were sown during 2011-2012. The source-sink relationship was analyzed using two methodologies: total biomass assigned to each pod during pod filling period (g pod-1) in relation to its final weight, and analysis of the trade-off between pod number and pod weight at harvest. The lack of trade-off between pod number and weight showed that the peanut plant has conditions to fill a wide number of pods (20-57 pods plant-1) in the same way. Also, the average pod weight (1.05 g) was lower than the total plant biomass assigned to that pod during its formation (2.63 g). A marked limitation by sinks was determined, indicating the possibility of to increase the peanut yield by means of improvements in sinks size. |

La partición de asimilados a frutos es una característica fisiológica de relevancia para el aumento del rendimiento de maní y su análisis mediante la relación fuente-destino aporta al mejoramiento genético y manejo del cultivo. El objetivo fue analizar la relación fuente-destino en cultivares runner sembrados en Argentina. Se realizaron dos experimentos a campo, en el Exp1 el cultivar Granoleico fue sembrado en tres fechas durante 2009-2010 y 2010-2011. En el Exp2 fueron sembrados seis cultivares runner (Florunner, Florman, Manigran, Asem-485, Pepe-Asem y Granoleico) durante 2011-2012. La relación fuente-destino se analizó con dos metodologías: la biomasa total asignada a cada fruto durante su llenado con relación a su peso final, y el análisis de la relación entre peso y número de frutos a cosecha. La falta de compensación entre número y peso de frutos demostró que el maní podría llenar un amplio número de frutos (entre 20 y 57 frutos planta-1). Además, el peso medio de un fruto (1,05 g) fue menor al crecimiento total de la planta asignado a él durante su período de formación (2,63 g). Se determinó una limitación por destinos, indicando la posibilidad de aumentar el rendimiento a través del incremento del tamaño de los destinos.
