Mediterranean clonal selections evaluated for modern hedgerow olive oil production in Spain

Abstract

Traditional olive oil production is limited by its high cost, mainly due to labor expenses for harvesting and pruning. A new olive planting system based on hedgerows and harvesting machines could decrease production costs while maintaining high quality. To improve the effi ciency of the continuous­straddle mechanical harvesters, vigor must be managed to limit tree size. However, few cultivars are adapted to this system. Selections from three cultivars are typically used in these super­highdensity orchards. We fi eld­tested ‘Arbequina i­18’, ‘Arbosana i­43’ and ‘Koroneiki i­38’ in an irrigated, super­high­density planting system in Catalonia (northeast Spain). We present a review of 6 years of horticultural data and summarize sensory characteristics and other properties of the resulting olive oils.
