At the present time, there are over 3000 cultivars, of which 60 are widely grown. Some cultivars have been known for a thousand years. Cultivars have been divided into soft and semi-dry, based on moisture content and an increasing proportion of sucrose, rather than glucose and fructose. Selection has altered fruit quality, storage, suckering, salt tolerance, and spininess. 2. Olive.
