The trial was carried out in two years (1992 and 1993) at two different locations in the centre of Italy (Pisa and Grosseto) and the main aim was to evaluate the influence of four different environmental conditions (Pisa, 1992; Grosseto, 1992; Pisa, 1993 and Grosseto, 1993) and the effects of two different water availabilities (without and with irrigation) on six sunflower hybrids: Ares, Cisa, Granada and Oleica, with high oleic acid content, and Gloriasol and Select, conventional hybrids (high linoleic), used as controls. The experimental scheme adopted was a split-block experimental design with five replications. The following characteristics were observed: duration of main phenological periods, plant height, leaf area index at flowering, aboveground biomass and seed yield per plant, harvest index, growing degree-days, water use and water use efficiency.
