This paper shows the results obtained in 2007 of a study carried out at the Sparacia experimental farm (Cammarata AG, 37 degrees 37'N, 13 degrees 42'E) aimed at identifying and evaluating 26 populations of "long-life tomato" collected from the Province of Palermo, Agrigento and Trapani. The farm, which belongs to the Sicilian Agricultural Development Agency (E.S.A), is located in a sub-arid area with average rainfall levels of approx. 500mm and average min/max temperatures of 9 and 21 degrees C. The soil is characterised by level land, deep soil with sandy clay texture and subalkaline soil pH classified as Eutric Vertisols, WRB (FAO-ISRIC-ISSS, 1998). The planting tomato crop was carried out according to traditional agricultural techniques using pocket sowing in paired rows with an inter-double row distance of 1 m and intra-row distance of 0.5 m, and a plant density of 4 plants m(-2). Analysis of the test data showed good yields, both regarding quality and quantity production, especially for certain populations, which could be of interest in research concerning genetic improvements. Good quality levels were observed for the populations '6', '14', '18' and '21', which were also the most productive.
