Its high resistance to the inclemency of the weather, its ability to adapt to different soils and its high-quality oil are all elements that determined Leccino’s success; however, it is quite sensitive to sooty mould. Medium-sized tree with spreading and quite dense foliage; branches have an upward tip. Good pollinator varieties for Leccino are Maremmano, Morchiaio, Piangente, Pendolino, Trillo, Maurino and Frantoio.
Inflorescences are quite short, with numerous, big-sized flowers. Abortion of the ovary rate is lower than 10%.
Ripening is early. Drupes often grow in bunches of 3-5, and they are not very resistant to detachment.
