Olive tree named ‘I-50’

Abstract

A new and distinct variety of olive tree, herein referred to by its cultivar name, ‘I-50’, is provided which forms a spreading growth habit. Fruit with a low weight and obtuse shape is produced. The fruit exhibit black coloration and the fruit nipple is either absent or weakly present. The stone of the fruit of the new variety is of very low to low weight, very elongated and possess a weakly rugose surface.

Claims
